I have an issue with my a/c, it will only work at first start up. If I start the truck with the air on it will work, if i turn the a/c off manually with the switch and then turn it back on it will not engage the compressor. I replaced the compressor, drier, and orifice tube, also tried using a jumper on the low side switch. So long story short the only way it will come on with out turning truck off and on is if I jump pins 87 and 30 on the a/c compressor relay. What could be causing this issue?
Thanks for your help.
