[QUOTE="red95r, post: 570299, member: 11491"] This a 95 V6 Mustang 3.8ltr, approx 131k :::::::::::::::::::::::::::::::::::::::::::::::::: :::::::::::::::::::::::::::::::::::: Prior to my problem I replaced my a/c system minus the condenser and the evaporator. I put in a new compressor, accumulator, liquid line (with orifice tube). Everything was working fine, even got it to go to 40deg in the afternoon drive. I had the shop do a vacuum and a flush. :::::::::::::::::::::::::::::::::::::::::::::::::: :::::::::::::::::::::::::::::::::::: Alright so the compressor decides not to kick on after I turned the switch, but it was working fine hours before. I have checked all the fuses relay's etc. Now, I found a forum were someone said to bypass the low pressure switch and see if it turns on the compressor, well I did this and it worked. So it must be the low side pressure switch right? OK so today I get up go get a new switch and put it on. As I take the old one off I here freon leaking, so I unscrew it faster until it comes off. Now I get the new one and put a new seal on and screw this one in all the way. 'Start the car and the compressor doesn't kick on. Now the freon reading is in the "need to charge zone". We tried the bypass the low pressure switch again and it didn't work this time. I believe I need to check all the fuses again, just to be sure since the bypass did not work. Also I did a check of the power cable to the compressor, and it reads .0514v when the the A/c is on. The fan does not come on either when I put it on max A/c .The new compressor has the connector on the side facing the fender wall so its a little hard to get to. I have put 8hrs of work time into this and countless time studying the a/c system for repairs. It safe to say I'm frustrated. Thanks for any help someone can give. [/QUOTE]
