Hey guys. Two months ago I bought a 2005 GMC Envoy XL (not SLT/no security system), 4.2 Liter, In-line 5. A couple weeks ago the Passlock light on the instrument cluster came on. A day later, all of the lights on the instrument cluster started going on and off at random (just really going crazy), and all the gauges stopped working. This kept happening intermittently over the next couple days. I'd go a half the day with no problem, and then non-stop problems the rest of the day. Just totally random. We took it to our mechanic who replaced the ignition switch and sent us home. It started happening again just a couple hours later. We called our mechanic, and he told us it had to be the Body Control Module. In the meantime, we had started having problems with the power shutting down completely on the vehicle while driving it. Usually when slowing down or accelerating rapidly. This seems to happen right at the same time all instrument cluster starts going nuts. We took the Envoy to a GMC dealer service center, replaced the Body Control Module, and had them program it. I took it off the lot, and the power shut down halfway down the road to the freeway. I took it straight back. They said they found a wire that was not properly grounded near the body control module. They said they fixed it, and sent me home again. That evening, I left to go to the store and the exact same thing happended as before...Passlock code, crazy instrument cluster lights, engine died. We took it back to the GM service center. They say they can't figure out what the problem is. The power actually shut down as we pulled into the garage. We showed them when we got it to start back up all the lights going on and off (flickering). They've had it all day now, and they say they can't get it to act up again to test it. Does anyone have any idea what might be causing this? We've now had our car in and out of shops for almost 2 weeks, and we've spent close to $1,000 fixing and replacing things that haven't solved the problem at all. We're just about out of money, and this is our only car. I would really appreciate any suggestions. I've looked around online, and seen plenty of people complaining about the same problem, not just with Envoys either. But I can't find many that have any suggestions. The only ones I've seen with any regularity are: Ignition Switch (which we tried), Body Control Module (which we tried), and Cam Positioning Sensor (which the GMC mechanic says he doesn't think it is). Help!!!!! Thank you, Mooncet By the way, the only other thing we've noticed is that moving the middle row seat (which happens to be right above the Body Control Module) seems to make it worse. It happens even when no ones touching it, but it happens more when someone is. I pointed this out to the GMC mechanic, and he tested it out when we first brought it back this morning. He folded it forward, and wiggled it back and forth, and it caused the instrument cluster lights to fluctuate. I'm sure that this has to be part of the problem. |

I have a 2002 Envoy, the back lights stay on, even when you cut the car off. What should I do to fix this? It drains the battery really quick! Please I need help to fix this problem, I am unemployed and have to fix it myself. Thank you for your help in advance! Kathy |

My daughter has an '02 Envoy that has the MIL on. This code reflects low operating temperature. My scanner shows an operating temperature of between 174-178 degrees. My question is, is this considered low? If so, this would be a thermostat problem. If not, it could be a sensor problem. Has anyone else had this experience? |
