Hello, I’m new to this forum and I was hoping someone can give me some advice on the issues with my car.

so I bought myself a Chrysler crossfire coupe a few days ago but the car has 3 issues which are the following:

1- The electric seats do not work

2- rear spoiler does not work( stuck open )

3- when I use the central locking to lock the car I get the indicators flashing with no alarm sound but when I lock the car manually using the key then it’s fine the indicators don’t flash

I’ve had a look at the fuses and the red 10amp and two 5amp fuses are blown I’ve changed them which made no difference and blew out again

the spoiler has no power in it at all so there’s no red light flashing on the manual spoiler button on the centre console I was thinking the spoiler motor has failed but if that was the case shouldn’t there still be power showing on the manual button as in the red light

any advice would be much appreciated

Thanks

 

Hi,
I will try to help.
1) Are you using your FOB to lock the doors?
2) Are the doors locking when you use the fob?
3) What fuses did you change that blew? This will help us determine issues. If the card is no longer present in your fuse box under the hood or dash there is a thread here that will lead you to the fuse numbers.
4) I would check under your seat and see if the floor is wet.
5) open your trunk and open the cover to your jack. Looking at the foam black pieces stick a piece of paper all the way down till you hit bottom down the far right side of the black foam pieces and if the paper comes back wet then we have a few more answers and can help with that issue as well.
There are people way batter at this than I am but this will get everyone started.

 

@Doc78

Thank you for your message

if I lock the car using the fob the car does lock but after half a minute the indicators start flashing (no alarm sound) but if I lock the car using key in door way then it also locks the car but this way the indicators don’t start flashing

the blown fuses are 2x 5amp fuses and 1x red 10amp fuse

im looking at other threads on here regarding the spoiler not working but everyone’s issue is the same where the spoiler doesn’t work and the manual spoiler button just flashes red but mine is completely dead there’s no lights at all when pressing the manual spoiler button 🤷‍♀️

as for the electric seats so the only option I have is to remove the seat? I did touch the floor under steering and behind the seat floor and it all seems dry and defiantly isn’t wet

Thanks

 

Your item #3 is correct in the way you describe, nothing wrong.
The cars did not come with a beeping alarm, the beeping alarm was added later when the original alarm failed or they just wanted to hear a beep.
The seat relay may be broken, it can be replaced or sometimes repaired. It could be a fuse or a bad wiring issue.
You later post adds more information that should have been here, nobody can give an answer if vital info is missing.

 

The well where the jack sits could be full of water and goldfish it would not have any affect on the locking system. The locking system pump is in the well behind the passenger, water in there leads to serious trouble and the cause of the leak should be found and fixed prior to putting another pump in the well.

 

Thanks for your your reply

to be honest I’m not to fussed about the alarm going off the main issues are the spoiler and electric seats where 3 fuses keep blowing which are most likely linked to the spoiler or seats apart from that all the other electrics work fine such as wing mirrors,stereo etc

 

To help more we need the actual fuse number I.E fuse #9. Which effects the alarm.
The relay for the power seat is located under the drivers side dash.
As onehundred 80 stated there is no chirp for these cars originally you can purchase a buzzer now that will chirp. Tread and PDF on buzzer removal is great here. I have mine off right now rebuilding it and purchasing the batteries to repair the old one if I'm lucky.
I have other things that you can try to tell us more.
1) lock the car with the windows down and reach in and open the car. Note alarm is loud and will sound so be mindful of others during this.
If the lights flash and no alarm fuse 9 or buzzer could be the issue.
2) Spoiler issue needs further information. Take the panel off from under the trunk lid. Id use panel tools or be very careful not to break them or stab yourself I have used a butter knife to do it before but be careful anyway. I would look at the connectors under there should be three if my memory serves me right. One going to the motor for the spoiler, one going right beside that for the position sensor for the spoiler. the last going behind the plate to the third headlight. Check for corrosion or them even being plugged in. A short at the motor could be causing the fuse to blow.
Without pictures or the fuse numbers( thread on here has all makes and models with fuse numbers) I can't help any further.
Hope I helped

 

Yes I'm sorry if I was unclear. I was talking about the area where the jack is located. The pump for the door locks and security module is located to the far right(passenger side) looking down at the trunk. I apologize again if I misled.

 

Thanks for reply and the information given

I’ve taken a picture of the fuses and put a arrow to the 3 which are blown

I’ve already removed the panel under the trunk lid and connections seem fine that’s as far as I’ve checked... if the issue is the pump which has died would the manual button on centre console still light up red when pressed?? Because if that’s the case and the button should still light up even though the pump has failed then it’ll mean the issue isn’t the pump itself and I have a problem somewhere else

 

CrossfireForum - The Chrysler Crossfire and SRT6 Resource >Technical >TSBs and How-To Articles
I listed the location of how to's and tsb above
I don't know what year your crossfire is so I cant help because the fuses do vary base on year model.(there should be a card on the top you removed that will tell you what the fuse controls).
I see that one of them is the fuse # 9 I mentioned above. The buzzer in these cars go bad and blow the #9 fuse. That is why I asked you to roll the windows down and then open the car from the inside. Note again if buzzer is good be prepared for loud alarm and have others be ready too.
If the lights flash and no sound(or sounds like a cricket on crack, you will know what i mean) buzzer is bad. There is a great thread here on how to replace/repair.
I will have to research what 6 and 7 do. Like I said there are really great people with way more knowledge than me on here.
I've had a bunch of this stuff happen to my own but I have a SRT so no wing issues for mine.( I have worked on my buddies wing) His was the position sensor went bad. Id still unplug the two that go to the spoiler and check for corrosion. If there is clean it with electrical cleaner and check for water in the trunk as mentioned above on the passengers side trunk area beside the molded black foam.
I've had the power seat issue. Mine just came unplugged under the drivers seat while moving something got stuck and popped off the connector but I learned quick where the relay was.
If it is quiet and you put your ear up to the driver side under dash and try to move the seat forward and back( don't hurt yourself) if you hear a click you know the relay is working and the problem is elsewhere.
I will try to help more when I find out what 6 and 7 fuse control.
Update
Fuse 7 could be your BCM. Here is a tread link to others that have had weird issues with it and where to maybe purchase a new one.
https://www.crossfireforum.org/forum...tml#post447032
Fuse 6 says it controls the mirror movement left and right on a coup I dont know if that goes through the BCM or not. Its located on the passengers side under the hood by the fuse box you took a picture of.
Again lots of good PDF and threads here to reference.
Hope I helped
Again not an expert here just put in quite some time on mine and my buddies convertible crossfires(mine SRT).

 

Thanks for reply and information

I’ve just tried what you said with the alarm so with the window down I locked the car using fob and then put my arm in and open the door using the door handle from inside and nothing happened apart from door and boot unlocking no buzzer or anything noise

my car is a 2004 coupe

as you can see from the picture I’ve attached above showing the blown fuses it’s the number 10 and 5 fuses

tomorrow I will undo the cover under steering wheel and check the sensor/relay if it makes a clicking noise when the seat button is pressed

As it’s 2 fuse numbers 5 and 10 I’m guessing one is for seat electrics and other for spoiler?

 

I got a picture that had three arrows pointing to fuses 6,7 and 9.
I will say now your buzzer is bad If fuse 9 is blown try replacing it (and do the same thing with the door) happens a lot and a great thread here to replace repair the buzzer.
If you replace fuse 9 and the siren works then you know but if it blows the fuse again Id disconnect the siren and see if fuse 9 blows again after you replace it.
fuse 5 is your radio and fuse 10 is your speed control.
I edited my last post to have more info on BCM issues.
Hope I helped

 

thanks for the info so basically fuse 9 is the buzzer.. I don’t understand how the fuse for radio is blown as the radio still works fine so that doesn’t make sense 🤷‍♀️

as you’ve said fuse 10 is speed control I’m guessing that’s the spoiler? Can you clear one thing for me if the spoiler motor is blown does the manual spoiler button in centre console still flash red when pressed? As mine does nothing when I press the manual button no light

 

Be sure you have the correct fuse diagram for your car. Not all fuse locations are the same on all crossfires. Was there a fuse diagram inside the fuse box?

 

yes completely understand but I have no fuse diagram in the fuse box... my car is a 2004 coupe with manual gearbox

 

The 2004 Owners Manual has the diagram of the fuse layout. You can download the Manual on this forum. Look for the Documentation thread, it is a sticky.
You should also get a copy of the 2004 Service Manual downloaded to your computer for help as well, it is in the Documentation thread as well.

 

I downloaded your manual and let’s see if I can clarify my comments here.
I think you are mistaken on the fuse numbers you have the arrows by on your picture.
when I look at the picture I see fuse 6,7and 9 with arrows beside it.
by your manual 6 controls your mirrors, 7 is bcm and a few other items.and 9 is buzzer and dome light and a few other things.
that’s why I would start by pulling the BCM and opening it up and check for corrosion and the solder connections. If it looks bad please refer to the link I sent earlier to get it repaired.
Id also pull the buzzer replace fuse 9 and see if it blows again if so we have a short somewhere else.
again just trying to help.

 

We do not call it a buzzer, it is an alarm or a siren. People added buzzers from Radio Shack etc. before the chirping alarm was introduced to the members here.
The BCM should not be damaged my moisture it is high under the hood and well covered.

 

Thanks for the information
so fuse 6 is mirrors
fuse 7 is BCM
Fuse 9 Is buzzer

someone else on here said fuse 9 was speed control but anyway you said fuse 6 is mirrors but both of my mirrors are working fine? 🤷‍♀️

either way first things first I need to remove the BCM and have a look at that from inside

 

NO NO NO The first thing you need to do is take the windshield wipers off, remove the plastic cowl that runs under the windshield and you will see the SIREN ( STOP calling it a BUZZER) and disconnect the damn siren!. Insert a new fuse nine and start your car. You can run around forever without the siren connected. Many of us do just that. It will not effect anything else, but it does eliminate some problems. you just won't have a security siren/alarm.

While you have the cowl off, clean out the four drains which allow water to run down and out the bottom of the car!
