Hi Guys,

I have an 2007 Silverado classic , 1500 WT, about 18 000 miles. I have never noticed a stale smell (or any unusual smell) coming from the air conditioner.The inside of the truck is very clean and everything is fine. The moment you turn the fan or A/C on it stinks badly...for real.

The truck is still under warranty but I don't trust local dealerships, I would prefer to fix it myself....

Thank you in advance!

JC

See if you can locate the cabin filter as it probably needs changing. I'm not sure where it is on your truck, but a lot of them are under the hood on the firewall somewhere. Hopefully someone else will chime in as to the location.

Thank you!

Thank you Gary,:great: that makes a lot of sense...I need to figure it out where is it, as you said. If anyone knows how to get to the filter will be greatly appreciated.

The drain for your evaporator may be plugged and leaving moisture in and on your a/c evaperator core causing it to mold and smell. Best bet is to check your drain and spray a disinfectant/mold and mildue remover into your air intake @ your cowl.

Thank you!:great:,
I'm not afraid to do anything mechanical, but I have no idea of how to find the evaporator. I do apologize for being so mechanically ignorant. I used to have the dealer repair manual of the car I owned before, but I'm clueless about A/C.
Thanks again,
JC

GM ditched the cabin air filter awhile. I really wish they hadn't though...

But I'd just take it to the dealer man. It's under warranty, let them waste their time and money on it. If you have issues with the dealer, just work directly with the service manager. Tell him the issues so he can make sure it's done right.

Thank you :great:!, I think I'll do that, even though I live in Miami and my dealership experiences here are awful....

Cab Odor

I had this same problem with my 2000 chevy 2500 series pickup. GM installed a odor kit on truck about 2 months after I bought the truck.

The kit turns the A/C fan motor on high for about 10-15 sec each hr. The fan blows across the A/C condensor and drys the moistrue off the condensor.

Unit runs 24/7, but it stopped the odor, odor was so bad my wife would not ride in truck. Smelled like wet clothes left in basket and not dried. (Bad)

Dealer said they had installed about 10 of the units, most people have never heard of "Odor Kit" but it does exist and it works.

Thank you Wellmax, :great:
that sounds like a solution, did you ever noticed if that kit had any effect on your battery? It sounds like eventually it will drain it out if you are parked for too long? That description of yours match exactly the description of what happens with my truck. I noticed it mainly the moment you start the A/C, it doesn't smell bad if I run the heater.

Thanks again,

JC

never had a problem with battery in winter as long as I drove truck to work each day, now that I am retired and do not drive truck each day I had one instance this winter when the battery was low.

must keep a good battery on vehicle and charged up, but nothing compared to the odor.

hope you get your problem solved with out some type odor kit.

Good luck.
