My uncle just bought a 96 cherokee and the a/c isn't working. I went to check the freon pressure and noticed that the compressor clutch cycle on and off for about 5 seconds. I bypass the signal wire with constant 12v and it stays on but the A/C wont blow cold air?? Any ideas on what it could be? Thanks

Sounds like the classic no pressure in system. AC systems have a low and a high pressure switches, low for freon leaks, high for overcharge/airbound systems. I'm not one for telling someone to go to a shop for work(more often they mess my XJ up not fix), but in this case you need the evac/recycle machine. Have it system evac, and recharged to correct weight, with some dye in for insurance. That way if there is a leak, you have a better shot of finding it.
