I recently bought a 96 XJ 2wd 4.0L to replace another xj I have thats been giving me too many problems. The prior owner of the "new" xj replaced the AC compressor when it failed with an idler pulley and looped the supply and discharge hoses together. I replaced the ac compressor, filter drier, expansion block, had the suction hose to the comp rebuilt, flushed the system and added 7.75 oz of PAG 100.
I took it to a shop to have the ac system vac and charged. The shop was unable to get the ac comp to engage on its on and was only able to charge the system by jumping the compressor wire to the battery. The compressor clutch engaged when they did so, and it blew out cold air. Also, during this time the electric fan never turned on.
Once home I replaced the relays for both the AC clutch and the aux fan as well as the 15 amp mini fuse that the owners manual describes as "a/c compressor clutch relay, radiator fan relay (4.0L eng.) EVAP/purge solenoid, low washer fluid level switch, park neutral position switch (auto trans.), backup light switch (manual trans.). The 30 amp maxi fuses for the radiator fan relay and the ac clutch relay both look good. The above is all in the PDC.
Now for the puzzling part- If I remove the relay for either the fan or the comp clutch then slightly reinsert it just right with the engine running and the ac on, then the component will turn on. Is this a wiring and or connector issue inside the PDC?
I know a lot of people say they need to get whatever fixed in a hurry, but I truly do- it was 113* here in Phoenix yesterday and my girlfriend is due to go into labor any day now and this Jeep is a lot easier for her to get into to go to the hospital in than my lifted XJ on 35s. So for mamma and baby I need to get it fixed.
Thanks in advance
