04 Tahoe:I had the same problem with my 04 Tahoe. It started
months ago, the heater kicked on with the a/c on high, it would only blow hot air.
Couldn't figure out what was going on, sort of an uncomfortable ride home, lucky it was short. Problem cleared after it sat and re stared it, and only did it one time more.
Then a couple weeks ago the battery was dead in the morning. Had to jump it.
I purchased the Tahoe used 1 year ago, and the battery was about 4 years old so I put a new battery in. Then I had a dead battery again after a couple days of not running the vehicle, I had to jump a couple of times the next week. I checked the battery and alternator free at the auto parts store, both checked good.
Took to trusted shop and cleared all codes then found one that would not clear or reset, the mode accuator for the hvac system was bad.
Part was $199 , total bill 391.00. Will post later if this did not fix the battery drain and weird heat a/c problem.

After reading forums, realize lots of us have similar problems. We got our car in 2006 and the first day bringing it home it wouldn't start. The dealership said it was probably because it had been sitting on the lot for a while... so we had it jumped. It is now 2010 and we have just put our fourth battery in, this time not getting the battery at the dealership but using a Sears Diehard because the guy who keeps coming out to jump it said the one that Chevy uses isn't strong enough, he gets these calls frequently (and from us, constantly). The day after the new battery we got stranded after just shutting the car off after a day trip in Tahoe, we stopped to get coffee and when we returned to the vehicle - stone dead. Anytime we leave the doors open, tailgate down, to vacumn the car (approx 20-30 minutes) the car won't start and needs to be jumped. Sometimes it is just putting the tailgate down. If we let the car sit for more than a few days without driving it, it won't start. The battery is always stone cold dead - nothing in the car will light up and usually having someone try to jump it with their car will not work, requires the tow truck driver's equipment. The other issue that has now come up is the door trim is discoloring, like rust - we've heard that they are recalling the 2008+ models to replace, but we haven't been included. We also lost our transmission at just under 50K miles - though the dealership repaired it under warranty. We love our Tahoe - WHEN IT RUNS! Hasn't anyone been able to get to the root of this eletrical problem? Does it require a class action lawsuit to get satisfaction? Has the GM gal, Mariah been able to give anyone the answers to these problems?

Were you able to get anything resolved with your electrical problems. I am experiencing some same issues. We have come out to a dead battery at least 4 times and we have only had the vehicle for 3 weeks with a whole week in the shop. If we leave the key on to listen to the radio it is dead in less then 5 minutes. They have already replaced a fuse block that was causing the rear lights to stay on after exiting the vehicle.

After a $350 bill at the dealership, their conclusion was that it was a bad negative cable to the battery. Huh? It's been replaced, and so far we haven't been stranded, but then again, we are really careful to not do anything to use the battery when the car is parked. I don't know if this is really the cause or not...they were talking about corroded battery posts, etc... but again, it died the first day we brought it home (brand new) and it's been nonstop since then - so I'm not buying it...I guess it's a pretty cheap fix to replace the battery cable yourselves and give it a try - $350 was pretty darn steep in my book!

my 2006 tahoe z71 has been perfect until the last 2-3 years when i started having one electrical issue after another..same thing over and over...in and out of the dealership over and over..sometimes for days. first the dvd wouldnt work..took like 10 visits for that to finally resolve. then i had the battery issue others have mentioned. heard if you leave ANYTHING on..phone charger, etc..it will zap it. greattt. just got stranded in the mtns after 20 min of shopping and needed a new battery. now i just dont trust it. its still making screeching noises from the radio when i turn the car off. its getting old. the car doesnt even have 55k mi on it yet. thank goodness its still under warranty (extended) and my dealership has been great...but its the hassle and now the lack of trust. we need to upgade to a suburban but now im hesitant to get another chevy..

I just got another mssg from someone else - the dealership ended up replacing the battery cables..... after four batteries and being jumped once a month, we have gone 1 month without calling our tow truck driver. We also replaced the last battery with a Sears Die Hard - but before the cables were replaced the battery discharged like all the others . . . was still new enough that it could be revived.... We are keeping our fingers crossed but we still carry jumper cables with us - ridiculous for a car that cost us over $55,000 and is a 2007.
