but when i'm going down the road it's fine; bad switch maybe, vacuum leak somewhere? really not familiar with this motor, 03 1500, 4.7.

 

Assume you have the recycle air on?

 

i don't even have that on mine.

 

Check the fan on the condenser (looks like a small radiator next the the radiator)...it should be on the whole time the a/c is on. If it's not on or is very weak then that's your prob. At idle you don't have air going through the condenser without the fan which causes the a/c temp to go up.

 

It's the biggest issue for me regarding these trucks. The AC just sucks at idle. The radiator design is brilliant; giving the condenser its own separate location & electic fan is ideal. Why it doesn't translate into cold air at idle in a real mystery.

I converted my 92 Chevy to efans and had ice cold air at idle. Maybe it's the refrigerant change (or level) but I don't think it's unreasonable to ask my 11-year-newer truck to have AC at least as good as my old one.

 

our clutch fan on our rads seems a lil small to me, so you gotta wonder when at idle where all the heat from the other rads are going? Dont forget the evaporator gets no air.... And the number one reason, aren't our compressors belt driven??????? Ding ding ding.

Ive always said I would pay 2 grand extra on a veh for an upgraded ac system, like having 8 vents, 4 in the dash, two in the ceiling and 2 in the rear. My mercedes had rear air but no ceiling vents. I can't imaging how ****ty its got to be in the back of a black mega cab.

 

Did not know that did notexist in 3rd Gens. Mine is just another vent option, roatated all the way to the left on the Hemi and a button on the SRT.

 

I had the exact same problem and discovered it was the compressor fan thanks to this forum.Bought one from ebay for like 60 dollars,replaced it like in 30 minutes and its as good as new.

 

Hmm - so how can I tell if my fan is going slower than it's supposed to? It looks ok but I don't have another Ram to compare it to.

 

simple stick your left index finger in its path and them stick your right index finger in someone elses, if the cut is smooth on both then its fine but if you have half a finger hanging on your left hand then its not runnig as fast.
