Question about 2006 Jeep Liberty
Last summer, I had the a/c compressor replaced in my 06 Liberty. It's not blowing cold again, so I took it in. The compressor & clutch are fine, so they replaced the PCM and checked the tranducer & pressure switch. All seemed good, and they're able to hot wire the compressor to get it to engage, and it blows cold. They're telling me it's electrical (something between the PCM and the compressor) and it'll cost me ANOTHER $325 to take apart my engine and just check the wiring. That doesn't even cover any further repairs, just the diagnosis. He also mentioned it may be the junction box? Any ideas or suggestions on something I can try myself before I unload a ton more money? And if it is something that I have to have repaired at the shop, what should be a reasonable cost? I live in AZ, and it's going to be hot VERY SOON. Thanks for your help!!
Well u can do it your self I'll walk you through it.. I tske it by pcm u mean the ecu or cars computer... Ok firstly start at the compressor.. I recommend u get a camera and take detailed shots of this cause u will need it... Remove plug from it and work your way back along the harness removing all the pieces of it until u get it out.. Now u have 2 choices.. The first is to remove the loom of the harness and replace any broken wires.. Or the second is 2 replace it.. With that done wire back up the harness as you took it out.. Now check the ac and compressor fuse and relay in the fuse box.. What they call the junction box.. If everythin is fine and it stil will not work.. Then run a positive wire from your battery to the compressor and a negative wire to the same.. Now the compressor will trip if its electronic if not forget that.. Check your dryer bottle , control unit, and the ac gas.. Can't see anything else causing this since that's the whole ac unit..
