I had help doing the 4.0 swap on my 89 about 2 years ago. Last summer was super hot so I bought brand new AC parts to install. Once they were installed I pulled a vacuum and tried to charge the AC system but the compressor clutch would not engage. At first I thought that it could be the low or high pressure switches, but then I remembered that my cigarette lighter does not work either. I'm an idiot when it comes to wiring, so I'm asking if anyone has run into this problem or if anyone could point me in the right direction. Thank you.
