Weighted Shifter Knob is Great!

NWGACarGuy — Wed, 20 May 2026 13:46:41 GMT

As the final step (I hope) in reducing the slop in my '04 Coupe LTD 6 speed shifter mechanism I swapped the OEM **** with a weighted stainless steel ****. I had to shorten the shaft in order to create a thick enough diameter to adapt the shifter ****, but that actually helped create a short shifter set-up and (I think) improved ther aesthetics considerably. The result is that the remaining wobble and slop in the mechanism have been largely tamed, the weight aids in moving more easily into the proper gear position, and the feel of the whole mechanism and process of shifting is much more substantial and smooth. If anyone is interested, I can post the sources of the parts I used and describe the process a little more specifically, Pics show the look, which fits quite nicely with the OEM cockpit and console.

Another random no start [Not RCM]

ahartig — Sun, 17 May 2026 20:35:47 GMT

I'm trying to diagnose another one of those random no start issues.

I recently got my 2004 coupe from my parents, who were not driving it due to their age. Car has 75k miles. Brand new battery.

Driving it back from their place in OR in March of this year, there was one instance of the car not starting, but otherwise it was fine. Since then, the no start issue has become a more frequent problem, sometimes happening 2-3 times before it would start -- but sometimes it would not be a problem for days. Recently I had an instance of a 10 minute period where I could not start the engine.

So far I have:

re-soldered the suggested RCM points,
replaced the RCM (when the re-solder did not resolve the issue),
and now tried the relay in the Pulse Control Module to further diagnose, as was suggested in this thread.

At first, pressing the PCM relay would just yield a click and no other activity from the starter. Then I tried the key just for kicks, and the starter activated and the engine DID start. Tried the key again several times after that, and there was a series of the starter activating but the engine NOT starting. I let it rest for an hour, and I was able to get the car to start using the PCM relay and via the key. All of the above were tried both with and without headlights -- there was minimal dimming.

Based on what I've read on the forum, am I correct in thinking now that the issue is with the starter or starter solenoid?

Thanks in advance for your help. This forum is amazing, and I've already learned so much reading through the many threads and posts.

Can't turn down heater

AlaskanArt — Sat, 16 May 2026 03:23:45 GMT

The heater control wheels don't seem to have any impact on the temperature. It is hot even when turned to the maximum green setting using the wheel controls. Has anybody figured out how to fix this? I also have a 1980 450 SL and this same problem occurred and was fixed with an after market control unit that replaced the original heater control valve in the engine compartment. Living in Alaska you need the heat in the winter, but not in the spring and summer.

The dreaded "no crank"

safossil — Fri, 15 May 2026 20:43:12 GMT

Hi
All,
We have a 2006 Limited convertible with an automatic trans. A while back it developed the "won't crank won't start" syndrome. After checking the battery (12.75v) I came to this forum & also YouTube to start chasing the problem. The consensus was that it was the RCM needing some solder reflowed. Took it out & upon examination found that the culprit terminals needed exactly that. Resoldered the unit. No help. So I bit the bullet & bought a new RCM. No help, plus I couldn't get the shifter out of Park. Whaaat???

Just for laughs I swapped the old RCM back in, figuring that with it I at least could get the car in Neutral. The damn thing fired right up. Whaaat??? Worked fine for a while. Then, no crank.

Swapped the new RCM back in. No crank, but the spoiler deployed. Plus, I couldn't get it out of Park (again). Put the spoiler back down & it fired right up. Whaaaat??? Shut it of & re-started it several times. No problem. Drove it around for a little bit. No problem. Shut it off & re-started it several times. No problem. Spoiler worked fine, except I didn't go fast enough for the auto-deploy to engage.

I'm really stumped here. I 'm glad it starts & runs, but I'm leery of taking it anywhere for fear of it taking a dump on me again.

The only thing I can guess is that there may be a loose wire somewhere in the harness or something else stupid.

Any thoughts/input/advice? TIA

limp mode nightmare

davidf30 — Thu, 14 May 2026 15:50:01 GMT

Please help. I am in Kerrville Texas. My 05 SRT6 is in limp mode. I just paid a guy $1300 to change the transmission conductor plate. He is telling me he has the mercedes software to clear the code and reset. The problem is not fixed. I asked him is it possible the new conductor plate he put in is no good? he said it would cost me another $1300 to find out. He is saying changing the conductor plate has not fixed the problem but reading these threads makes me wonder if maybe the problem is fixed but the software to reset is not working. Any advice would be much appreciated.

Long term storage control module issues

MrMoPar — Mon, 11 May 2026 18:45:34 GMT

I have a 2004 Crossfire that has been stored inside on a lift for 7 years with no power to the electronics. I will be retrieving it later this year. Should I expect issues with the control modules once powered up again? Any advice/suggestions appreciated. I am already planning on purging fuel system, replacing fuel pump, filter, and injectors and fogging cylinders before attempting to start it.

Coolant line broke off

nickwe21 — Fri, 08 May 2026 21:44:06 GMT

Hi everyone!

Have an issue. The coolant line to the reservoir popped off when I cleaned the engine. What is the best way to fix this so I can drive the car on Monday?

Is there an easy fix/temporary fix and what part do I need?

Thanks so much for your help!

911: Windshield fluid receptable: Discontinued :(

StephCrossfire — Fri, 01 May 2026 22:20:37 GMT

Hi:

1) I've just spent an hour trying to find part 5096729AAMopar...It's shown in bunches of store sites, BUT no one has it. I called the manufacturer, Mopar: And that was just weird.
They sell roadside assistance, etc...and I spoke to phone bank in Asia.

My receptacle is cracked from top to bottom. I drive this car every day and have for 16 years, not kidding. It's in great shape. Any ideas? No on eBay, also.

2) and while I have you. This is laughable, but not. My seat "sometimes" cannot be adjusted (motor-powered...) Yesterday, after a car wash, I couldn't move it. I drove home pulling myself forward and trying to SHIFT manual gears. It was awful. Like, I was a wreck when I got home, and then...it started working. Anyone have this issue?

I realize I am in no man's land now with the car. It's gorgeous and it's my friend. I was told this would start happening and IT is here.

Thanks for any help. I'm in OC, CA.

2004 Crossfire No crank/no start

jrwnjr88 — Fri, 01 May 2026 22:08:36 GMT

Hope someone can help. I have a 2004 Chrysler Crossfire I bought for my Wife from the dealership in 2004, so one owner with about 50k miles. My Wife no longer drives it and the car has been in the garage for several years now. I have always maintained it changed oil, had it inspected, charged battery, started it and drove it around the neighborhood occasionally. I have had RCM issues and have had to re-soldered twice, both times it fixed the problem; apparently only temporarily. Now I am in a no crank/no start status again after about a year in the garage. I do get the high speed fan after about 30 seconds, but nothing happens. My question is how can I get the RCM fixed permanently or do I just need to purchase a new one? I also installed a battery cut off switch to disconnect the battery during prolonged storage; is this possibly a problem?

Thanks,

I�m having trouble with my crossfire, I need guidance.

Clovis — Fri, 01 May 2026 18:02:33 GMT

Hello, I purchased my 2006 Chrysler Crossfire Limited Coupe back in November and it�s been a lot. But the issue i�m having and needing assistance with is after a large rainstorm. My vehicle will turn perfectly fine, nothing out of the normal. But when i start driving and getting to 40mph, I feel that my car isn�t shifting gears automatically. The engine revs louder than normal and the RPM will continue to rise without the gear shift. It is an automatic. I�ve looked to troubleshoot the car and used an OBD2 Scanner and got 3 codes. P0301(Cylinder 1 Misfire) P0600 (Serial Communication Link) and P0128(Coolant Thermostat below regulating temp). While driving for no more than 10 minutes, a clear smoke started coming out of the hood of the car. I couldn�t determine the smell but it looked like steam. I opened the hood and also couldn�t tell where it was coming from. I let the car sit for a few days before checking again thinking it was possibly water. But i had the same issue with the smoke coming from the engine bay and will not go over 40 without that high RPM issue. Ive been looking all over the place, and I am hoping that I can get guidance as to where to start looking to resolve the problem, and/or maybe find someone in the SATX area that works with these vehicles. Any and all information is extremely useful.

It�s an odd thing.

Crossfiredennis — Mon, 27 Apr 2026 20:56:33 GMT

I have an issue with my 2004 Chrysler crossfire. When I go to start it it just turns over. Nothing I then shut it off and try again, this time nothing no crank nothing. Then when I shut it off and turn it back on it cranks right over. Driving it has no issues no lag in power just rides perfectly. Anyone else have this issue. Also a garage had it for a year didn�t fix it. They did how ever parts change the **** out of it. Any thoughts. Love my car.

Won't Start and Speedometer says Oil High Light.

Tre'Louis — Fri, 24 Apr 2026 05:16:34 GMT

Hey Y'all, I haven't been on here in a min. I was driving my crossfire and in the speedometer. It will beep with the oil sign, and it says high. The thing is I have oil in the engine, and I have coolant in the car, unfortunately. I have to send the skreem, ecu mods back in as well to get reset. Because ruby won't start. Did anyone else have this problem? What do I do?

Supercharger shim size and harsh engagement

nickwe21 — Fri, 24 Apr 2026 04:32:05 GMT

So I recently replaced the bearing on my aftermarket 65mm pulley.
Could be coincidence but ever since, I hear a "metal" sound when the Supercharger engages. Could be a chirp but sounds more like a rattle.

At the same time, it just seems like it's a harsher engagement. So I checked the pulley gap. If memory serves me correctly it's supposed to be between 0.25mm-0.35mm.
It's closed at the moment but it's not rubbing on the magnetic plate.

1) What is the correct gap?
2) I never needed a shim before and I cannot find the shims that came with the OEM pulley. What is the thickness and size (diameter) of the OEM shims? I want to have some made just in case. My machine shop will make them for free
3) Is the harsh, jerky engagement a problem? Some people think as long as the backing plate is not rubbing against the magnet,life is good?

Should the measurement be taken when components are hot or cold?

Do you guys take sandpaper to the backing plate to smooth it out?

For some reason I feel like power is gone. But maybe I'm just imagining that.

Thanks for all your tips.

Central Vacuum Pump Placement

mistykup — Wed, 22 Apr 2026 13:55:57 GMT

Does anyone know if it matters how the pump is bundled back into the guts of the trunk?

When I got it last fall, it was a mouse nest heaven and everything came out for washing/ gutting and I forgot to take a picture of how this was stored.

The sound deadening foam was saturated and tossed in a frenzy of disgust. Now I can't find any dimensions to remake and I don't remember how it was secured.

This was the only item I could find on ebay that had a picture, but i don't need to buy the pump.
