So my 04 WJ since I got has a few problems, the a/c compressor doesn't come on the compressor activates and the lines freeze but nothing comes out the front. The overhead console doesn't work I already checked #8 and #20 fuse and wiring it's good. And the courtesy lights don't come on when I open the doors all fuses and bulbs good.. And to my understanding all this is tied into the bcm I already replaced the pcm with a new one. Any opinions?
