I just got a 2008 chevy silverado crew cab and I am having the same. I was wondering if you ever found out what the problem was and what the solution is. I would really appreciate your help.
Thank you for your time,

Our issue was the window switch that went out. We had to replace 2 switches and the cruise control relay switch. Total out of pocket was much less than we thought since it was only the switches that needed to replaced vs window motors.

I have an "08 GMC Sierra 3500 and my ghost turned out to be a loose ground on the frame under the driver's seat. There are several grounds attached to the frame. If your truck spends any time in the cold climate, I am sure that you have noticed rust on the frame. GM's solution for corrosion control was to have the frames dipped in some sort of wax instead of painting them like the rest of the world. As soon as a single drop of water gets behind this wax it is all over and the wax starts to literally peel off. When GM installed the grounds to the frame they never cleaned the connection point off and the grounds were screwed on top of the wax. This works for a little while but once water gets behind that little 10mm bolt and freezes a couple of times, the wax and the bolt are loosened and the grounding point is compromised. You would think that they would have a service bulletin on this by now. You would also think that GM would have gotten away from those waxed frames by I just took a look at a 2012 and yep, wax frame that was already rusting. Reminds me of the early 70's. Check all of your ground points. Loose grounds drive the ECM's bonkers.
#744 of 768 Shift indicator messed up

I have had this happen 2 times now. After driving my 2008 GMC 4x4 the indicator for the shifter keeps loosing P,R,N 1,2,3 and all the lines under them ------- it starts off with one disappearing then one by one they disappear. until they are all gone. Then all of a sudden they are all back just like nothing happened

#748 of 768 Re: 2001 not starting after rebuild [smxtuner]
Nov 21, 2012 (7:16 pm)
I rebuilt a 2002 and it fired right up...no ignition timing needed, but im no mechanic...that same truck is forgetting the key occasionally and I have to train the key to the truck for ten minutes before it knows it not being stolen and will allow it to run. After u attempt to start the truck leave the key in the on position and if the diagnostic screen on the dash flashes the security light at u then back to the battery light leave it on for ten minutes until the security light is no longer flashing then turn off and retry...sometimes it has taken two to three times of doing that then all the sudden it will fire right up and no problems untill that sob forgets again...have no idea what keeps cusing this to mine... good luck maybe this will help u
#749 of 768 Fix for Silverado Electrical "Gremlin"
Feb 08, 2013 (9:58 am)
Has anyone resolved the electrical "Gremlin" as described in post #556? I have experienced this and it is quite frightening while driving. Called my local dealership and he said he had never heard of anything like that happening. Don't want to waste a bunch of money there if they have no idea what is going on. Seriously considering a trip to my local Ford dealership for a trade. What a shame, I really like my Silverado.

There was a guy on here that documented similar problems on youtube and it was scary. He apparently got some deal from GM and the youtube video was erased. MY GM truck lost brakes early in life due to brake lines that rotted out in less than 4 years. Endless warranty issues and I was nearly always greeted with the "deer in the headlights" look at my dealer, but at least they fixed at 1-3 warranty items at nearly every oil change ( several repeats in 3 years) . I know of many accounts of the early failing brakes, and in fact it was investigated by NHTSA, only to see the case suddenly closed. GM Customer Service kindly contacted me on this board, only to tell me, 'sorry, we know nothing about those brake line that burst early in life' (many accounts on the internet though). After 35 years, I bought a Ford. You will be glad you did. Had a warranty issue, no deer in the headlights look, they just fixed it.
