#70 of 459 2000 Chevy Tahoe Electrical problem?
Mar 21, 2010 (6:24 am)
I have a 2000 Chevy Tahoe that has been giving me major problems recently. The first time it happened I was sitting in the car with it idled and the interior lights on. Suddenly the lights started flashing on and off, the radio kept going in and out, all the indicator lights started flashing and it started making a weird clicking sound. I turned the car off and tried to restart it and it wouldn't turn over but the lights and radio, GPS, and locks kept going crazy. I swear it was like the car was possesed! Finally the battery just died and I had to get a jump and it started right up. I took it to my mechanic who said there were no problems he could find. The battery, alternator, and wiring all looked good. His only suggestion was that the after market upgrades we added could be going bad and interfearing with the system. (GPS, satellite radio) Since that time the car has run with absoluely no problem until this morning when the car wouldn't turn over. It just kept clicking and all the electrical components of the car including the alarm started going crazy. UGH! I'm at my wits end. Any suggestions?
#71 of 459 04 Tahoe Electric Problems
Mar 28, 2010 (3:05 pm)
I drive an 04 Z71 Tahoe and have many electrical problems that come and go on their own. Currently I am experiencing problems with the AC and Heat. By Itself, it toggles between heat and cold. If the fan it turned up the heat will go off, but again, at times the heat will stay on.
The 4 wheel drive will show SERVICE 4WD, which I have. The 4 wheel drive will engage on its own, in low, I need to turn the vehicle off and on and eventually it will kick back into 2 wheel drive.
The heated seat on the drivers side will kick the heated seat off on the passenger side off.
I am some what frustrated as I have brought my vehicle in for repair and after spending money on diagnostic testing I still have the problems.
Any thoughts I could share with my local dealership before dumping more money trying to figure out the problem?

Hang a test wire off the main power buss at the fuss box, and monitor the voltage on the buss, to see what is happening when you have any failing conditions See if you have a main power buss voltage problem (voltage dropping too low), or it is good.
If buss bad, check battery, alternator, main cables and connectors, grounds.
If buss good, check BCM.
The service manual should have a whole series of things the dealer should check.

Did you ever figure out what was wrong? My Tahoe passenger door lost all power, windows, locks and heated seats. The key fob stopped working at the same time. Also - when the truck is running and the door is open, it doesn't register on the dash. You can't open the window from the drivers side either. Basically - this door no longer exists. Thanks in advance!
#74 of 459 Cruise control disengages when turn signal is used
Apr 22, 2010 (6:39 am)
I have an 2009 Tahoe and when I use my turn signals or use the front window controls, the cruise control disengages. Does anyone know why this may occur? Also the "Service Stabiltrack" indicator light has come on a couple of times and when I use the window controls, the indicator light goes away...Thanks

#78 of 459 1997 Tahoe dies while driving
Apr 27, 2010 (9:13 am)
I have a 1997 Tahoe with 4WD and Vortek engine. The problem I am having is that my truck dies while I am driving it. I have to pull over, put in neutral and try to restart on the fly. No joy. I am out of ideas on what to fix. Sometimes it starts right away, sometimes I have to get a jump, sometimes I have to turn truck off and then it starts, sometimes I am dead to the world like the battery is completely dead. I wiggle the battery cables and I am ok.
1. Changed out battery. No change.
2. Changed out negative cable on battery. No change.
3. Fixed ground straps on engine compartment. No change.
4. Altenator 45 amps at 14.1. Looks ok?
I recently had my fuel pump stop working because of a broken ground strap in the engine compartment. That is why I am focusing on electrical issues.
Also when I turn on blower, rear defrost my voltage drops and my lights dim momentarily.
I am out of ideas on what do work on. It is super frustrating not being able to trust vehicle to go to work.

Used to have a 97 Sub, but don't remember all the specs.
45Amp out of the alternator seems low, I would have expected 100+ amps. Call a auto parts store and have them look up the alternator specs. Most will check your alternator and battery with a load tester free of charge. They put them under full electrical load, and check whether the alternator can put out full voltage and amperage, then also check the battery can hold it's charge and delivery rated output.
