Yukon Air Conditioner problem
Posted 27 June 2002 - 07:40 AM
I've had it to both a GM dealer and a local private shop. Both of those just let the truck idle out in the lot and it performed flawlessly. Then I took it to a third garage. They claim that the head control unit (the dash control module, where you turn on and control the heat & air) needs replacing and that its a very common problem on these trucks. Also they want to replace a clutch relay. In all about $375.
Has anyone replaced their dash control unit for this kind of problem? I'm just a little skeptical about their diagnostics. If this control unit is a big problem why didn't the other 2 places suggest it?

Make a note of how it sounds when the clutch engages. When driving do you hear the same engagement/disengagement of the clutch? If not or intermittent, along car's line of thought, it could be a short or bad connection to the compressor.
