Does anyone know if it is required to remove the negative battery cable before replacing the Cabin Air Filter. I have read the thread on how to do it and there is no mention of it there. It's hard to find anything in the Service Manual about the CAF, although there is mention that before you tackle anything in the instrument panel you should disconnect the negative cable. I just got the charcoal filter from Advanced Auto and there is a generic warning about disconnecting the negative cable. Anyone know for sure. Don't want to disconnect if I don't have to. Not sure what all has to be reset after disconnect.

 

You shouldn't need to disconnect the battery at all when replacing the filter. There are two screws underneath the glove box. You will need to be a contortionist.

 

There is no need to remove the battery power for this installation. Regardless, if you ever do need to remove the battery, it might be a good idea to pick up a $5 plug in power adapter for the cigarette lighter, just to maintain all of the vehicle's memory settings. I don't think the job is onerous or difficult, even for a guy my size! I would suggest though, that you put an old towel or similar on the floor before you pull out the filter. There may be a "gush" of cr*p that comes out and it is best to catch it before it gets on the carpets. https://www.crossfireforum.org/forum...er-change.html

I did a post on this about a year ago, with photos. The biggest surprise was the difference in the weight of the old vs the new filter. Testimony to the amount of stuff that the filter caught!

 

no need to disconnect battery, its a 3 minute job, remove 2 scrws under dash, old filter comes out, make note of its orientation on the way out so you can put the new filter in the same way.

 

+1 on that. It is a very tight fit in the pocket so be warned.

 

Thanks for all the replies. I'll get after it. What a great site. Nice to know that whatever the problem, someone has been through it and has an answer. Thanks again.

 

It's really not that bad. A few minutes on your back in the passenger footwell and you're all set. I didn't find the new filter all that hard to slide back into place. BTW, I went with the carbon filter but I don't really know if it helps with odors. I can still smell stuff like diesel fumes, skunks, etc. while driving.

Contrast the Crossfire experience with my wife's Infiniti G35x where the cabin air filter is a dealer serviced item and the Mercedes design doesn't look so bad. Infiniti made the filter all but inaccessible for the average person.

 

I do my best work on my back...wait, what?

 

I've already changed my filter (without disconnecting the battery) but am about to put in a new battery in. The idea of keeping power to the car while I change out the batter is intriguing. What are you referring to when you say a $5 power adapter?

 

just change your battery, nothing to worry about.

 

I just did mine over the weekend thanks to this post. It's amazing what a dealer won't do. Clean fresh air now! Thanks.

 

I agree with Doc... just change the battery and don't worry about it. Other than the trouble codes, I don't think that Crossfire has any volatile memory.

However, if you have several vehicles it might be handy to have one of these simple devices on hand.

They maintain your engine trouble codes(if any), radio settings, things like that.

I've read that it's a good idea to keep power to the ECU but since it is flashed to memory, I don't really think it needs power to have it maintained. Radio settings, seat settings, mirror settings, Climate Control settings in my Avalanche though ... you either use one of these or re-programme it every time you disconnect the battery. For $5 it is a good idea if you have vehicles other than a Crossfire.

Perhaps a forum member can help determine if there is any volatile memory on the Crossfire that would benefit from one of these.

 

The ESP light comes on if you disconnect the battery, but that is an easy fix.
The radio may lose its settings, I've forgotten if it does or not frankly. I remember someone said it does not but I cannot remember if it happened to me. I'm thinking my memory is getting more volatile as I get older.

 

I got a charge out of your last comment, Dave! That cue sparked an idea I heard about from a friend of mine ... I'd say that you're feeling that way (volatile memory), simply based on current thinking! You should Keep positive and try not to get wired about all the negative stuff - it's polarizing!

What did the Dalai Lama (and I guess too, the Moody Blues) say? "Ohmm .."

Okay ... I'll stop!

 

Had my heater core replaced a while back and the service guy took out the original cabin air filter during the service. Couldn't find anything of value in the service manual about where it was located so I really appreciate you guys letting me know where to put the new one in at. Thanks to all posters! Vern

 

It's been a couple of years since I saw a thread on replacing the cabin filter and I vowed to replace the filter in my cars.

Still haven't done it! Maybe this weekend!?

 

Try this on for size.

Not just for SRT's

 

+1 on this, especially the hint to put towels down on the floor to catch all of the crap falling out. I was able to do it w/out any issues, and I'm 6'1", 265#, and had a cast on my right leg at the time.
One question I never thought to ask is "Why is there a large piece of styrofoam under the passenger floormat?"

The large styrofoam piece is to cover the amp and other electronics down there......


Disconnecting the batter will NOT cause loss of radio programing.... or anything else that I have found..... I disconnect mine frequently and haven't had to re-do anything..... (I dont use my NAV so I will exclude that from my comment).....

 

Many thanks for the concise explanation on the link.
