    When I bought this Jeep I was told that the AC clutch or compressor doesn't work. I was told I would have to replace the AC lines and was given ac lines to replace the old ones. I noticed there are some missing pieces and broken/burnt connectors. Can you guys take a look at these pictures and tell me what I'm missing and tell me what kind of problems it can cause ?PHOTO_20191026_141926.jpg PHOTO_20191026_141949.jpg PHOTO_20191026_142108.jpg PHOTO_20191026_142028.jpg

    With these pieces missing, can it affect performance?

    A/C system with unknown history can be problematic for DIY repair. For example A/C lines missing for an extended period of time will require total system flushing. A/C compressor failure for various reasons usually call for condensor, dryer, etc replacement to be done right.

    Had success with DIY a/c repair this summer with two important tools: a/c manifold gauges and vacuum pump from HF. Figure on about $120 for both. Picked up the compressor, drier, condensor etc from autozone/advance with 20-25% coupons.

    You got a vacuum pump AND gauges both for 120$ not 120$ each !! - the pump worked pulled into the high 20's?

    HF vacuum pump worked great and held the vacuum past the 20s overnight. Got to use them 20% coupons.

    Should I reroute my engine belt without using the AC? If my AC isn't working wouldn't that cause problems to have the belt running running it ?

    If the a/c clutch is not engaged and the pulley is not making noises I don't see any immediate issue.
