    AC Compressor clutch?

    Hi all, I think the clutch on my AC compressor has gone. It was slowly rotating, producing some cold air, then would blow the #30 fuse under the hood. Each time I replaced the fuse, it would blow. Thinking the clutch is gone. Has anyone had success in replacing the clutch only? Recommended...

    To V8 or not to V8? That is the question

    Hi all, I realize it has been ages since being on the forum, but that is because our 6cyl Envoy has been remarkably good to us.

    Hi All, My Envoy has a pretty nasty dent in the front passenger door. I have an opportunity to purchase one, exact same colour in excellent condition for far less than the cost of fixing the dent and repainting.

    Fuel Leak, top of tank?

    Hi All, Started noticing a smell of gas over the past few days. Peeked under the truck and found the bottom of the fuel tank to be wet, dripping infrequently. So I have read there could be some recall coverage out there, but I fear my 2003 SLT 7pass. with 235,000km might be out of luck? Is there...
