I know this is the mustang forums but i thought you guys might have an Idea. After about 100 miles travel time in my dads truck 2002 dodge ram the a/c would stop blowing cold? I thought maybe his fan clutch but it appears to be working, the condenser has an electric fan but it is also working. Could the problem be the belt? The truck has 60000mi on it and is the 4.7litre if that makes a difference.
 
There is a known problem for the condensor fans crapping out on that model year ram- but if that is definetly operative- then your out of luck here. Check the condition of the condenser to see if the fins are blocking air flow. Good Luck with that
 
ac

im a technician... First off weather it be ford,dodge, chevy, whatever doesnt matter ac is ac

If you have a set of ac gauges connect them to the high and low side of the ac system... Start the vehicle and turn the ac system on max... make sure your ac compressor kicks on... At that time get your gauge readings... the high side on a hot humid day shouldnt go much over 200 but should stay around 180 190... and the low side should be somewhere around 25 to 40 no higher

if the psi arent within these then you most likely have a leak... And then i suggest bringing it to a dealer or local shop... they will have to reclaim the system add ac dye and then check to see where the leak is coming from ...

i hope some of all of this helps
