#85 of 459 2007 Chevy Tahoe-Electrical/Possible Security Systems Failure
Jun 06, 2010 (5:37 pm)
2007 Tahoe LTZ has an issue of not starting. Battery has been checked and is good. Will hear clicking noises in the door and have been told that this is a security system failure. Sometimes after waiting for 10 or more minutes it will start back up. At other times jumper cables have to be used to get it started. Grounding has been checked and is find. When the issue happens the remote won't work and none of the lights will work.

I also have a 97 tahoe that has electrical problems. My fuel pump relay sometimes doesn't make contact because the contacts in the relay block are bent from someone sticking a volt meter probe in them when my fuel pump went out. Check the bottom of the relay out for melted plastic to see if it's been arcing out. I put a 1/4 thick scotch bright pad between the top of the relay and the cover to help it make a better connection.
Hope this helps if you haven't figured it out yet.
#89 of 459 2004 Z71 Tahoe

I have a 2004 Chevy Tahoe Z71 that has 106,000 miles on it and it runs great. For about a week the volts reading on the instrument cluster has been erratic, and now doesn't seem to be working at all. It started out fluctuating between 9-14 volts and then it went to 19. So I stopped at a local parts store and had them check the battery and it checked okay. Yesterday when I drove to work the gauges was pointed full right deflection down to the picture of the battery on the gauge, and it hasn't moved. So, what could it be?

FIrst thing to do, is to verify that the gauge is correctly reading the voltage on the battery. Buy yourself a voltmeter, can be as cheap as a couple bucks to maybe 10 or 15. Tool supply stores, auto parts chains, Radio Shack, many places sell them. Measure the voltage on the battery posts, as well as the voltage on the wire terminals, and compare to what the internal dashboard gauge says.
I would first suspect a bad battery or corrosion on the battery terminal connection, or a bad/loose ground. But you could have a failing voltage gauge.

Are you aware of a cluster problem with 04 Tahoe's?
I own a 04 Tahoe and the gauges became erratic. Over time all my gauges were effected and I had to have the cluster replaced. That is when I learned of the wide spread problem.
I had it replaced about a year ago, and at that time, there was a "discount" for the cluster depending on the miles on the vehicle.

#92 of 459 Heated Seats heating me up!!!
Jul 12, 2010 (12:22 pm)
I have a 2005 Tahoe LT with the power heated seats. Well they just started coming on all by themselves. Its only the divers side and it comes on full blast and then cycles down to off and back on again.
It seems that the computer or relay thinks the switch is being activated- the switch on the door panel does not appear to be stuck in or anything.... Any/all help is much appreciated!!!

#94 of 459 Tahoe Gauge problems
Jul 14, 2010 (9:42 pm)
I have a 2003 Tahoe with some gauge problems that seem to be intermittant. First it started with the speedometer. It would be fine, then freeze in position. If you turn the car off and then restart, it would start returning to zero. Of course that's if you start the car a couple of times to get the needle to "bounce" back to zero. Most of the time it's just the speedometer. Just today, I noticed the engine oscillating in RPM and the A/C fan doing the same. Doesn't do it all the time. Now the oil temp gauge is acting up. On a drive home, the temp went all the way to 80. Of course I stopped and checked the oil. Everything was fine. The water temp was in the normal range so I wasn't too concerned. Once I got home, I checked the voltage across the battery with the car running. The voltage reading was 12.9...well below 13.2 to 14.6 that its supposed to read. Figured the charging system was due for a check up. Checked the battery with the car off...voltage was 12.9. That's actually okay. Then restarted the car and found the battery voltage was reading 13.8. About normal for a charging system. (Scratching my head...) The speedometer thing has been going on for quite a while. Thank God I use a GPS so I know what my correct speed is. Now that other things are starting to crop up, I may have to take it somewhere to get it looked at. I am very disappointed in this vehicle. I spent over 40K on this thing. To have these electrical problems does not look good for GM!
