What owners wrote
I have a 2002 trailblazer with a air condition problem the truck has been to the dealership twice. The dealership has told us to spray the trailblazer with lysol in the air condition vents in oder to keep the meldow smell from coming back into the truck ,they are refusing to replace the air condition.
When I first bought my 2002 trailblazer, the fan clutch would occasionally be fully engaged when I started the truck in the morning. It usually resumed normal function within a mile or so. As of yesterday, it will not disengage and the check engine light came on. It sounds like the labor to replace this clutch is very high. I'm not sure if I dare tackle this myself, but the thought of paying $700 to replace something that shouldn't fail at 47,000 miles is disgusting.
