My 09 Tahoe was in specialty auto electric shop for a couple of months. Picked it up last week and have about 500 miles with no problems whatsoever. They found several modules that were the wrong part number - onstar (VCIM), radio, rear seat radio/module and the instrument panel cluster. They updated all the other modules in the GMLAN system. They took the time to methodically go thru every module and associated component - the Chevy dealer just threw up their hands to say "I dunno". The dealer techs are inexperienced and are on a pay schedule that isn't compatible with repairs like this that require experience and willingness to troubleshoot. However, I still think the main problem is the GMLAN system's inabiltity to troubleshoot itself. It's poorly engineered, period. Although I like my 07 Tahoe that's never had a problem, the fact that the dealer could never solve my electrical problems with my 09 Tahoe is enough for me to say that I'll never buy another GM vehicle. Never buy a GM vehicle. Never buy a GM vehicle, get it?

Talk about wanting to rip my hair out. I have an 07 Tahoe that just quit starting. I replaced the battery and it still just gives you one click when you turn the key. Everything works lights, seats, windows, horn, etc. But when you turn the key you hear one click and thats it. Funny thing is it has done this before and jumpstart worked. Now....Nothing works!!

Good morning scuba_steveo,
I realize that this post was from a while back and I apologize that it was missed. Have you had any success in moving towards resolving this?

No Sarah. No luck yet. It was dead from last Wednesday to yesterday (Tuesday). I tried jumping it a few times over the weekend with no luck. Again the only thing that happened was a clicking in the doors. Everything else is dead. No lights or gage movement or anything. Yesterday I had it towed to a mechanic that I have been to who does good work. If you email me at stevenkfwengineers.com I will give you their contact info. They were able to get it started but cannot find the problem. They told me to leave it with them for a while and they will keep looking. This is very upsetting to say the least.
#243 of 456 2005 Tahoe Electric Seat Fuse Blowing
Jan 23, 2012 (6:55 am)
Have recently been having the electric seat motor & heater fuse blowing, but only when the emergency pedal is depressed. No issues when emergency brake is off, but if you engage emergency brake, the 50A fuse under the hood is blowing right away.
Saw another posting which implied this was a known issue, but no info on how to correct it.
Any tips appreciated.
#244 of 456 07 Tahoe electrical problems??
Jan 26, 2012 (6:12 am)
Ok so I have a 07 Tahoe LTZ. The truck runs fine most of the time. But I am having a problem with the wipers turning on and spraying fluid all by themselves. I swear I have to turn the truck off and take the key out for it to stop. I thought the first time I hit the button but I KNOW that it is not me. It happens especially when it rains but has happened on sunny days as well. All of the sudden I will be driving and bam the wipers come on an spray fluid all over.. Also my wipers although the stick has like 5 different speeds it only has 2 speeds which are slow and fast.. there is no in between. Is anyone else having this problem? And what the heck can I do to make it stop!!

I'm sorry to not have responded earlier! Sometimes the search tool we use doesn’t catch everything, and when I have time to do so, I go through the forums manually.

There may be a short circuit - would you please email us the last 8 digits of your VIN (as well as your name) so we can check to see if there are any open recalls on your vehicle?

Well it is now January and my Tahoe is still in the shop....it has been in the shop for 47 days since November! They cannot fix...won't come right out and say that but I was asked why i won't just trade it in. Easy for them to say when they don't have to take a loss on a verhicle. I am so frustrated..why won't GM fess up and fix the problem or is it so much easier to just pay off law suit by law suit? Our Tahoe ended up in the shop this past week (On Jan 18 and I still do not have it back yet) because as I was driving once again the car started cycling through and in the past the brakes would pulsate..this time they grabbed really hard and the Tahoe came to an abrupt stop and then sped off again (oh...because my foot was on the gas, i never even touched the brakes!) poor lady behind me...no brake lights because I didn't hit the brakes--thankfully she didn't hit me. And that wasn't my first tight situation...driving down the freeway and the car starts cycling again-car won't shift-and then it stalls...on the freeway at 70 miles an hour...I steer to the side of the road and then it comes on again--i over correct and almost hit the person in the lane next to me.... I was told by the dealership that they have heard of this happening and are sure they can fix it...nope stalled again once we got it back...oh yeah the cycling, transmission problems, not shifting is all in a service bulletin that GM put out so they are well aware of the situation they just don't care if someone gets injured because of their vehicle. This is so frustrating to me. I hate putting my kids in this vehicle, I have to alter my driving route to work because I am afraid to get on the freeway with it...I just don't understand with all these problems reported over and over and over again they just won't fess up to it and find a fix or buy our cars back! I don't understand how they can get away with it.
