    Glad to help guys.
    A few weeks ago I might not have known what it was but I had one that I spent a while tracking it down on.

    If I know it, I'll be more than happy to pass it on.

    Re: That fa*ting noise again

    I asked my dealer to fix this problem. She laughed when I described it and wrote up the service order using my colorful words, but said she'd never heard of such a problem. Picked up the car and the service order said can't duplicate. I'll have to print this and bring along it next time. I'll also take the service manager for a ride to show her how embarrassing it can be.

    The A/C also goes into recirc mode now whenever the car stops moving or slows to a crawl. Then back to normal when the car starts moving. I don't think it did this before. Has anyone ever seen that? It's as if the fart alerts me to the fact that the Navigation display is locking or unlocking.

    Re: That fa*ting noise again

    I complained to dealer about noise under the seat. The dealer located TSB 03-08-50-010. This bulletin covers noise from under the left front seat cushion. The corrective action is to install rubber hose on adjuster rail, whatever that is. Will let you know if this solves the problem.

    This other noise for the HVAC recirculation door has a TSB with updated parts now.
    It is indeed a clearance issue, the kit has new parts in it with a special lubricant to repair this issue.
    Just tell your dealers to look at this:

    Re: Farting or groaning noise from climate control system

    I just printed the bulletin and I'm going to take my car in too. This is a very embarassing noise. I always have to give the disclaimers every time someone new gets into my car. It can be a funny ice breaker when I have a new girl in my car!

    Re: Farting or groaning noise from climate control system

    I have installed 3 or 4 of these kits with great success.
    It is actually not very hard to do either.
    The bulletin calls for removal of one of the ducts but I find it very difficult to get the duct out and back in. I can be lowered in the dash for access to the retaining screws.
    If you don't want to hear it, you have to manually override the recirculation door position. Just put it on recirc and it won't do it.
    Otherwise whenever the computer automatically switches to inside and back to outside air it will make the noise.
    If you want to entertain your kids you can press the recirculation button over and over, they might think it is funny.

    I took the bulletin number #06-01-39-009 into my dealer and the farting noise is no more! It was fun for a while, but gets old fast. Works like a charm now.

    Re: Farting or groaning noise from climate control system

    Just took mine in today for an oil change along with the bulletin number that I printed from here. They ordered the part which should be here in a few days. Kids do think it's hilarious but I hate when adults give you that look like, "Are you trying to sneak that one by?"

Can't defrost the pass. side window, get heat on that side, etc. Just trying to find out how much this will cost me.

    Re: Farting or groaning noise from climate control system

    It sounds like an air control 'door'. You'll likely find someone with the same experience on the Seville STS forum for those cars before model year 2005.

    Re: Farting or groaning noise from climate control system

    I agree. I have seen several with "sticky valves." An easy fix that has worked for me is to adjust the temperature control from full heat (90 degrees) to full cold (60 degrees). Set it to "90" and wait about 20 seconds and then go to "60" and do the same thing. Do this about 5 or 6 times and a lot of times, this will "unstick" the door and then it will work properly. Otherwise, you will have to remove the glove box module & then check the link for the air mix door.

    Cool Re: Farting or groaning noise from climate control system

    If anyone had the inclination to "DO IT YOURSELF", I have 2 posts, about this,
    asking exact locations,Procedures, etc, then the second one, where I have
    completed it, and the results, and the procedures I followed.
    Have Fun !
