#44 of 100 Re: 2003 Tahoe a/c thumping noise when accelerating [jmillet] by jaymoore74 Sep 10, 2007 (10:01 am)
Replying to: jmillet (Sep 06, 2007 7:18 am) I just took my 2003 Tahoe (55,000 miles) in for the same thing. The mechanic found a bulletin from Chevrolet that discusses the problem and the solution. He printed it out for me. I am trying to find it online right now...but haven't yet. Basically, the 2002-2004 Tahoes/Suburbans have faulty air conditioning compressors. And they seize up. I thought it was just the A/C belt, and I replaced that, but I kept hearing the noise when I accelerated. So I eventually took it to a mechanic, they replaced the compressor and dryer ($900 when all done), and everything works great.

#46 of 100 Help...my blower won't shut off. by hockeydaddyo Dec 03, 2007 (9:11 pm)
Replying to: jaymoore74 (Sep 10, 2007 10:01 am) Hi, I have a 05 Suburban LT and just recently the blower motor for the front heater keeps running after the ignition is off. I opened the hood and pulled the fuse which temporarily fixed the problem, but now every second or third time I run the heater it happens again. I don't understand how it is getting direct power after the ignition is off and the keys are in my pocket. Anyone with a suggestion...please reply. Thanks from ice cold Ontario Canada.

Replying to: hockeydaddyo (Dec 03, 2007 9:11 pm) As I was registering for this forum to comment, my dealer called and told me that I definitly had a short in the resistor control module causing the "mind of it's own" . They replaced it and fixed a leak in my front axe. Both under warrantee, thank God I bought the extended warrantee at the time of purchase last Feb. Good luck with yours.

Replying to: mickgz28 (Feb 09, 2007 7:43 am) I have the same problem with my 2001 Tahoe as well, thanks for the information. Did you install the flapper valve yourself and if you did how much work was involved? Replies to this message: boersen (Dec 18, 2007 5:49 am)
#50 of 100 95 suburban defroster will not work by boersen Dec 18, 2007 (5:49 am)
Replying to: alaska7 (Dec 06, 2007 4:54 pm) I have a 95 suburban. All the settings on the heating control work accept for the defroster. I can turn the dial to that setting but nothing happens, and in Michigan, that is not a good thing. Any ideas as to what is wrong and how to fix it?
#51 of 100 2003 AC switches only at 90 degrees by punkieys17 Dec 18, 2007 (10:19 am)
In my 1500LT the fully automatic air con switches from blowing cold to hot or hot to cold only when the temperature selection is turned up above 90 degrees (or to 89 degrees or lower). On fully automatic the system will keep blowing hot (90 degrees or above indicated) or cold (89 degrees or below) AND NOT STOP.....   Can anyone suggest where I start trying to cure this.   I was thinking either of the aspirator (cabin temperature sensor in the roof lining) or the thermistor sensor in the footwell) - but which should I try first.   As a related question can anyone suggest a decent scanner to connect to the vehicles electronic systems - and would they show the sensor readings?   Any help greatfully received as I am over in England and there is just 1 authorised dealer for these vehicles.   cheers and ta-ta from Julian
#52 of 100 2004 Tahoe Rear Climate Control Issue by wyrman332 Jan 21, 2008 (3:26 pm)
The background of the problem is that I had absolutely NO control of my rear climate control. The blower motor always stayed on. even ran the battery dead. I replaced the ballast resistor and the fan ceased to run 24/7. I then had no control of which vent the air was coming out. I replaced the rear temperature sensor (little speaker looking device), and now I can control the transfer between the floor vents and the celing vents.   Now the problem is I cannot get ANY heat. Is there something I'm missing?
#53 of 100 no heat drivers side 04' Suburban by matgilbert Feb 06, 2008 (9:20 pm)
I have a 04' AC works fine on drivers and pass' side drivers side blows cold no matter where the temp control is set. I can change it from floor to dash to defrost but it is always cold air. the passengers side get nice and toasty. Does this sound like an actuator?
