#51 of 63 99 tahoe dying by grandbayoulabs Dec 03, 2008 (12:22 pm)
My daughters 99 tahoe/350 2 door dies sometimes while driving down the road. It will always restart and go on. I have heard that corrosion on an electrical harness or a sensor on the timing assy could cause this. Where is this harness and what would you try 1st? Andy

Replying to: ksmith5 (Aug 08, 2006 6:40 pm) To any Tahoe/Suburban/Sierra owners who are experiencing undiagnosed or intermittent electrical problems involving the ABS light/Parking brake light /door locks/ message center/ 4wh drive buttons/ chimes/ etc etc I will identify the simple fix. This fix was suggested to me by a Tahoe owner who was experiencing the "Dashboard Disco" as I was on my 2003 Suburban Z71.   The fix seems too simple to be valid but it has solved the issues on my truck so far.   There is a black/yellow wire that is grounded to the top rear of the engine block on the passenger side of the engine. This ground connection evidently gets compromised by corrosion or oils over time, or it becomes loose. I cleaned the surfaces on my truck and reinstalled the ground. I have not had any electrical issues since doing this.   Regardless of whether you believe this could fix the problems you may experiencing it is certainly worth a try.

Replying to: not2l84u2 (Oct 24, 2008 10:24 pm) Don't know if you solved this or not; I just started here. But on my 2001 Tahoe you have to hit the dome overide 4 times not 3 as someone else suggested. Its also how my manual explained it.

Two more payments and it is ours and I had a knot in my stomach about this until I read this message and am hopeful it is my issue too.   It is definitely worth a try as it is dead-in-the-water. If I cannot do the work myself I will take this suggestion to my mechanic.   Thanks for posting a possible remedy.
#57 of 63 2002 TAHOE DASH GOES NUTS by boobesmootcher Apr 05, 2009 (8:07 pm)
i have a 2002 tahoe z-71. car runs fine and starts great. while going down the road, the dash goes nuts. the message center flashes battery,security,low fuel. the gas gage and temp gages go up and down. the airbag, abs,seat belt light flicker on and off. oilpressure gage and volt gage are not affected. voltage reads 14.5 all the time this is going on. the other day i tried to get a look at the ignition switch. i took 2 screws off the bottom panel, but couldnt figure out how to get the big lower panel off. so, i got the 2 pieces off around the key and got a look at part of the switch. i just tried to move things, and in the process the car would only run in the start position. as soon as you let go of the key, the car died. then it started and worked ok untill the dash went nuts again. it has done this intermitently for the last 30k miles.i think i want to replace the ignition switch, but dont want to make a $164 mistake. any help would be appriciated.

Replying to: ahp (Nov 08, 2008 2:53 pm) I have a 2007 with the same problem. Check codes and 22 came up. Told dealer keep it and drive it because Battery dies. They have had the thing for 2 weeks now and It been fine. They are waiting to see what pops up in codes again. The Biggest thing is the Dome lights come on and the door locks go crazy. You know the battery will be dead when you try and start it!

I Have a 2003 Chevy Tahoe z 71. the problem is that while driving the battery light will turn on and and all the gauges will go down and power right back up. The car will not turn off just seems like battery is trying to die. I replaced my battery after car once dying. But now it is a brand new battery and i still get my battery light to turn on and off. Another issue is my reader states i need it engine oil and i have 4qts still inside. Please Help. Replies to this message: kiawah (Nov 10, 2009 6:58 am) tahoee09 (Nov 10, 2009 9:33 pm)
