Ac not working in grand cherokee
It finally got warm enough for me to turn on my ac recently, just to find out that it is not blowing out cool air. I checked the fuse and relay, both good. I got a cheap gauge and refill bottle of r134 from the store. The initial reading on the low pressure side was nothing so I verified that the gauge was working on another car, and it worked fine. So I figured the system was low and preceded to put the r134 in. after the whole can, pressure still read nothing and compressor was not kicking on. Anyone have any ideas that I can try next? I know the compressor will turn on because it comes on for a second then turns back off when I push the ac button. If you need more details, just ask. Thanks for the help. Its a 02 with straight 6 if that helps.
