well my A/C doesnt work, the compressor at first didnt do anything, so i bought the recharge kit and followed the instructions, the compressor cycles and i have pressure in the system, but no cold air? should i drain the old refrigerant out? i dont have a clue how A/C systems work, any help would be appreciated

 

no air is blowing or its just not cold?

 

its blowing hot air

 

does it have enough freon in it

 

how do i check that?

 

with gauges ,also do the conrols seem to be operating proprely when changinhg from hot to cold setting

 

this might help narrow down the issuehttp://www.jeep4x4center.com/knowled...ex.htm#service

 

well all the controls are digital, and it says its on LO and my A/C is on, when i plugged in the recharge thing it had a gauge on it and i said i was at the correct pressure without even letting any refrigerant in

 

ac should be on max blower and the lowest temp setting if compressure is staying on and not cycling sounds like a door maybe is no opening allowing the switch from hot to cold

 

thats what im being told from some experts, now is it normal for the compressor to come on and off about every 5 seconds because i looked at my buddyes car and his stays on the whole time, and everytime the compressor kicks on the pressure in the system drops to almost nothing then starts to build back up when the compressor kicks off

 

You dont have enough in it. Your measuring from the lowside and adding from the lowside right? Psi amount varies with outside temp.

 

compressoer should not be kicking off and on either you dont have enough in it sounds like to me

 

Actually it will when it gets to the set temp. All cars do it.

 

well everytime i try to add some in, the pressure skyrockets

this is what i bought ...http://contentinfo.autozone.com/znet...p/345/image/2/
