Question about 2000 Jeep Grand Cherokee
About two years ago I had everything related to the A/C system under the hood replaced. It worked great for a few months but this year, even though it is fully charged, it is only blowing slightly cool air. I suspect it is the orifice/expansion tube and want to know if I can change it out myself or reair it.
Rather then guessing an just replacing parts , have a qualified repair shop hook up A/C manifold gauges an check the system . Can tell you what's wrong in just min.
(it is only blowing slightly cool air. I suspect it is the orifice/expansion tube and want to know if I can change it out myself or reair it.)
Don't suspect , that's guessing . test don't guess . Are the A/C pipes going in through the fire wall cold ,have ice on them when A/C is on ?

There is a compressor relay "fuse" under the hood (in the fuse compartment). It is black and has a "diode" symbol on it. I replaced mine and all was well. Good luck.

It could be your low pressure cycle switch is going bad. Check the connection to the switch and it's is located on the A/C Accumulator. The other thing to check is the A/C relay and that is located in the glove box. There is a panel in the glove box that say's relay, there is three relays in there and one of the out side relay's out of the three is the A/C. can not remember which one it is. The middle relay is the fuel pump and the other one is the third break light. Switch the two out side relays and see if your A/C get's better. the other thing too is if the R134a is just a little low, and needs to be topped off. Good luck and hope this helps. if your going to try to recharge the A/C system your self, keep in mind not to over charge.

sounds like the clutch field on or bearing on the front of the compressor went bad take a closer look at the pulley on the comp. and see if there is any debris or melted plastic coming out behind the pulley,if so the clutch,field and bearing should be replaced,hope this helps
