Have Jeep Questions? Ask a Jeep Repair Expert for Answers
Good afternoon and welcome to JustAnswer!!My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help.
I work part-time here on JustAnswer to help you and other repair their own vehicles, and I get credited by your ratings.. So before leaving the site make sure and leave me a rating. You can still reply to me as many times as needed, even after the rating.. I will need for you to be my hands and eyes since I'm not there, and to be honest with today's electronics a scantool may very well be needed to retrieve the codes or to monitor data to see what's going on...
Is it full or freon? WHen did this start? Do you have any codes in the HVAC system? What is your VIN number?
Do you keep having to add freon? Did you add a/c dye to locate the leak?
Does the compressor have 12v and ground when it won't come on?
If it has 12v and ground then your clutch is bad and it will need to be replaced..
If you don't have voltage then remove the a/c clutch relay and tell me if pins 30 and 86 have 12v, then see if pin 85 has a ground.. To test the compressor you can jump pins 30 and 87 which will send 12v directly to the compressor..
What did you find?
Remove the a/c clutch relay and tell me if pins 30 and 86 have 12v, then see if pin 85 has a ground..
The relay needs a ground on pin 85 from the PCM, it needs 12v on pin 86 and when it has these two it will connect pins 30 and 87. Pin 30 comes from fuse 21 and 87 goes to the compressor.. If it's cutting on and off you will need to see if your loosing the ground on pin 85 or the 12v on pin 86, once you know this then you will know what to test next. Test at the compressor to make sure it's loosing voltage then test the relay. You will need to find what your loosing in order to find the issue..
