so alright charging the ac didn't turn on the cooling fan here's the deal I've gone thru everything fan works relays good clutch on compressors good here's my point there are four commands coming from the pcm and not one is working so I'm getting a list of people that have had problems in general I'm ready to order my new computer next week .its crazy I've been working on this thing for about 3 days i even went thru and ohmed the switch perfect no issues help oh I've put a full can of 134 in it so good pressures.

 

When the A/C engages, is it sending a signal to a relay?

Are you getting a signal from your high pressure switch?

Do you have a wiring diagram for your Jeep?

 

no power to the relay because i have nothing coming from 4 outputs from the ecm i figured it out last night yes belive it or not ive got the entire 00 manuel on my computer 1528 pages of it which i love any how ya im a tech also ... im ordering a computer tomorrow yes no relay excitement because nothing from the computer.... thank god i only payed 500 for this thing but ive got about 2700 in it now but its money well spent the value of these rigs is headed up....
