Replying to: airtindi (Oct 29, 2008 8:23 pm) For sure you have an electrical short, start out by checking all your fuses, your manual will show where the fuse boxes are. bb   The back of the insteerment cluster has a main power supply plug that supplies power to the inst. cluster as I recall the power to 4wd is independent from the inst.cluster power supply. This makes me think it could be a main ground short.   There are a number of ground straps from the engine to the frame all tying back to the battery ground.   You need a volt meter The cluster is easily removed 1. Trim bezel 2. Cluster screws   Sorry if that sound like a lot of unknowns to follow-up on, the fact is that there is not a simple answer with out checking a number of possibilities.
#121 of 236 2004 GMC sierra 1500 4x4 transfer-case problem by joker762 Nov 13, 2008 (5:17 am)
I've got an 04' Sierra 4x4. Here's my problem. Sometimes upon starting the truck the lights on the dash for the push button 4-wheel drive will say it's in 4-low. It's not. It also won't switch out of the faulty light by pushing the other 2-hi or 4-hi buttons. Sometimes when it says it's in 4-lo, it will actually drive in the 4-lo gear range but it won't be in 4-wheel drive. On the days when you start it and it says it's in 2-hi, you can push the buttons and it will switch to either 4-hi or 4-lo with no problems. Also sometimes the red light is on in the panel between the buttons. Do i have a bad actuator or bad dash switch or something else?? HELP!!!

#124 of 236 2005 GMC Sierra stuck in 4 wheel low by nardi1 Nov 12, 2008 (5:57 pm)
My GMC is shifting itself into 4 wheel low and wont shift out. Its push button 4wd. If I shut the truck off for 10 minutes and restart it, it goes back into 2wd by itself. I talked to a local mechanic and he had no ideas other than to pull the fuse so it wont shift. This has been fine for the summer but winter is coming and I'd like to get this fixed. Any ideas?
#125 of 236 LT245 tire pressure by tafid Nov 26, 2008 (5:54 pm)
I have a Silverado 1500 4X2. There are LT245 70R 17 tire on it. Max pressure is 60 psi. The message board says check tire pressure. Question is can you run at recommended pressure (about 35 psi) under normal running (no load), but inflate to higher pressure when loading heavy cargo?     Replies to this message: obyone (Nov 27, 2008 1:38 am) tafid (Nov 30, 2008 11:45 am) obyone (Nov 30, 2008 1:37 pm)

Replying to: tafid (Nov 26, 2008 5:54 pm) that is exactly what you should be doing. Replies to this message: tafid (Nov 30, 2008 11:45 am) obyone (Nov 30, 2008 1:37 pm)
