My old Jeep AC was working fine then just stopped blowing cold air. I figured it probably needed a shot of freon like in years past, so I bought some then noticed the AC's electric clutch does not engage so the compressor does not turn. I have a GM truck with a 'low pressure' cut out switch but I am told this Jeep does not since I can not find it. It does have relays everywhere--, most I have no clue what they are for. Is there a relay somewhere that could be bad or something simple I can check myself?
