my jeeps air conditioning is not blowing cold at all in hot weather. The cluch fan im not sure what its called though it is not engaging much like it used too it does not make a click noise when air conditioning is on when vehicle is running.

 

check the charge in it. if i remeber right if it's to low it will not come on

 

or a low press switch

 

I have the same issue, my evap core is leaking. I want to attempt to run some leak sealer through it to get it to work at all. I know the odds aren't great, but I don't want to get into the replacement of the core just yet, if at all lol. I've heard of running a jumper wire to the compressor, but I'm not sure of the recommended procedure. Is a 12 gauge wire from the + side of the battery to the compressor right, or do you just make a "U" out of it and plug each end into the compressor somewhere?

 

well you could spend 20$ for 134a or 200 or more for a new compressor up to you

 

After checking the forum, which I know I should have done first BTW, I jumpered the low pressure switch, and it kicked on. Now for part two of the program, dumping stuff in the system.
