I have a 2004 Tahoe that the rear heat and A/C is giving me fits. I was getting no heat in the rear(front was fine) so I checked the heater hoses to the rear of the vehicle and they get hot. So I replaced the blend door acturator in the rear. That seemed to work for a little while but now it is 50/50 whether you will get heat in the rear.
View 6 Replies2004 Tahoe that started with no heat in rear. Checked all hoses and they get hot all the way to back. Replaced rear blend door actuator and worked for a little while. Tonight, took a 90 minute trip and it blew ice cold until suddenly it started blowing heat 45 minutes into trip but then went back to cold after about 10 minutes. Actuator is electric not vacuum. Could it be in the controls where you adjust the temp?

View 3 RepliesMy 2007 Tahoe is leaking a bluish or greenish fluid from the rear driver's side. I have not looked to see exactly where the leak is coming from, but was wondering what this could be?

View 1 RepliesI have a 99 Chevy Tahoe that the transmission keeps going out in. I've replaced the torque converter, cooler lines, computer. I've even added an additional cooler on the truck and it keeps burning three the transmissions.
View 3 RepliesMy brother's truck is a 1997 , 5.7 L gas engine, fuel injected. 100k+ miles.
New plugs, wires, new rotor, coolant temp sensor & air filter & recent battery.
Started a few times after the new air filter & some dry gas & fuel injector cleaner & that was the last time it started.
Turns over but will not run! He needs this truck to tow a trailer to R/C boat shows (he makes parts for R/C racing boats).
I have a 2001 Chevy Tahoe. My ABS/Brake lights have been on for awhile now...they go off intermittently, but I think my ABS module is bad. This is a very expensive part.
View 2 RepliesI have a 97 Tahoe that I love! The problem is that, every once in awhile, it simply won't start. Won't start, won't crank, won't do anything. I turn the key and nothing happens, similar to having the truck in gear and trying to start it. The REALLY frustrating thing is, when I take it to the mechanic, they can never recreate the problem. This last time, the mechanic had it for a couple of weeks, couldn't ever get it to not start. I had it for a week, and it stranded me an hour and a half from home.
View 4 RepliesMy wife has a 2004 Chevrolet Tahoe with abut 100K. She did something and doesn't know what but now the car beeps anytime you put it in reverse. No big deal, it's just annoying. I've checked the book and can't find out to disable. How to disable this on a tahoe or know what to look for in the owner's manual.

View 8 Replies98 Tahoe ac giving me warm air once again. 5 weeks ago had it in the garage. they found a leaking schrader valve and re-charged and added dye. checked it and didn't see anymore leaks. they said keep an eye on it and if it stops cooling bring it back. well.........it's going back! it's blowing warm air even though I hear the compressor kick on. what else could be giving me problems? of course i'll take it back but i'm just wondering if a switch failed this time or what the heck is happening. I was surprised to hear the compressor running with warm air.
View 14 RepliesI have a 2004 Chevrolet Tahoe 2WD with the 5.3L V8. Tahoe has 134K. At about 125K miles, I replaced air filter with a K&N, new OEM spark plugs and spark plug wires. The Tahoe has been running great and was getting normal mpg until recently. 15mpg in town and 17mpg on the road is what I normally get. The last 3 fill ups my mpg has been below 13.5mpg. Car still runs great but at 13mpg it's starting to hurt a little financially. Weather here in NC has been normal, my driving conditions or habits have not changed, etc. What could be causing my mpg to drop by so much while the suv still rides smooth and straight?
View 4 RepliesMy 2002 Tahoe cranks over fine (new battery), but, will not start. I have checked the fuel pump relay and have control power to energize the relay, but. no switched power from ECM to change relay state. Jumped rely 30/87 and pump runs. No DTC's. Gauge on instrument panel reads no fuel. Scanner shows 56% level. Tried to use my Snapon MT2500 to switch relay state and received error message "generic device control limit exceeded" ECM?
View 3 RepliesMy 95 Tahoe smokes bad on startup (coolant) and a little (oil) on accelerating from zero. There is also a large internal coolant leak. I just replaced the intake manifold gasket as it was the easier fix; didn't do anything. Does this mean it is definitely a head gasket? Anything I can do in the meantime until I have time to pull the heads?
View 1 RepliesI have a 98 chevy tahoe and the truck seems to make a strange noise sometimes when applying the brakes. I can feel (sorta) the noise in the brake pedal. Is this something that needs a scan to find out where it's coming from?
View 11 RepliesIt happened as I was stopped at a traffic light. without warning it just revved up as though I punched the gas pedal, which I didn't. had my foot on the brakes but it still wanted to fly! I dumped it into park and it really howled! I shut off the engine, started it back up and everything was fine! what the heck caused this and what needs fixed?
View 7 RepliesI have a 1996 Chevy Tahoe (5.7L, 185k miles) that I think is misfiring. What typically happens is a shuddering at about 50-55mph while in 4th gear (though to a lesser degree, it will shudder at speeds above that too) and lightly accelerating or keeping speed on a small incline (~5-10% grade). During this time, there is no change on the tach. My check engine light is not on. Spark plugs and wires are new. The problem occurs while using 93 octane fuel. The shuddering is never noticeable in gears 1, 2 or 3, and is not noticeable at full throttle. I replaced the fuel pump about 6 years ago.
I brought it to the transmission shop, but was told that isn't where the problem lies. Second, I took it to a mechanic. He told me that he couldn't pin-point the cylinder, as there were no codes to unveil the problem.
My question is what are the causes I should look for, and how can I address them short of an engine overhaul? I recently read for the first time about Seafoam, and I'm intrigued.
What fuse controls the engine compartment Light?
View 7 RepliesChevrolet Tahoe 2007
This service light came on 2 weeks ago. The next day, the car seemed to be trying to switch from 2 wheel to 4 wheel drive. Took it to the dealer who found nothing. We drove the car for 2 days without any service lights coming on. Then the switching ( 2 to 4 WD) started again, but this time the transmission would not go above 1st gear. Pulled over and turned off the engine, then tried to restart it. Nothing. Dead. A few minutes later, we go it back home. Had CAA tow it back to the dealer. It's been a week and they found nothing. They are looking for engine codes that would explain the problem.
Is this an electrical problem or a sensor issue?
I have a 2004 Chevy Tahoe , the doors keep locking and unlocking. The abs and brake lights come on and stay on. When the doors act up the engine light comes on . The best is it'll stall out. Doesn't happen every time , but 99%
