It has been a long time since I have posted here. I have a 2004 Jeep Liberty that I'm thinking the compressor or clutch may be bad. When I hooked up my manifold gauges, both low and high side show about 90psi. The system still has refrigerant in it. I tried to add refrigerant, but the compressor would never engage to allow refrigerant to go in. I did, however, find a blown fuse in the Power Distribution Center under the hood. I replaced it and was able to get voltage. The instant I connected it to the compressor/clutch, it blew the fuse.
Anyway, since I am reading 100psi on both high and low side gauges, could I be looking at a faulty compressor?
That gets to another problem. I bought my gauges from this site about 10 years ago to do readings and I think they were faulty out of the box. I was offered a new set, but never really got around to getting them back to the sales department for a replacement set
If it is the clutch that is bad, would it be worth it to go ahead and replace the whole compressor, accumulator, orfice tube, and o-rings/seals? Rock Auto sells a kit for about $180 that has everything I would need. The only thing I am missing is a good gauge set, vacuum pump, pag oil, and refrigerant.
