99 XJ AC issue.
Well I changed out my AC compressor and clutch late last year and it worked great after putting in the recommended oil and R134a. As the temperature got hotter this year I have ran my AC only a few days. Yesterday I was running the AC and it was running just fine when I had to hit the brakes a little harder than normal and I noticed the air coming out was warmer. It never got better. I went to the AutoZone and checked the pressure of the low side to see if I was missing Freon but the pressure was off the scale. The lines coming from compressor was hot as usual but the line going in was warm along with the lines going from and to the evaporator. Normally these lines are colder. I have heard many stories as to what to replace but I am not made of money and wanted to see if someone has had this problem before.

Here is a great writeup on how to re-charge the system.
http://www.supramania.com/forums/sho...system-at-home. The only way to know if you have the right amount of r134 in the system is to completely empty it and re-fill it. Do not just add some thinking you are leaking some... I blew a system in a honda doing that... if you do have a leak you should fix it sooner rather than later so that any damage that is done by moister in the system will be minimized. I know that doesn't really help you, sorry Nathan |
