04 EB 4.6 Having issue with my AC. When I am at idle, in traffic at very slow speeds under 10 mph the AC is not blowing cold air. When the vehicle is moving the air is blowing cold. Would this mean the clutch fan is bad? How hard is this of a job to do by myself?

We're having something similar with my '05 Expedition, but I assumed it was just because it was SO hot. I don't know the answer, but will be watching for someone who does.

Hi, my 94 dodge does the same thing. I believe it's supposed to work that way. takes the load off the engine at low power situations with the smaller lower power engines we run . been that way since new with mine.

Really, the only way to know for sure is to have a trustworthy tech check it's performance.
