I have replaced the compressor and checked the 134a and I just can't seem to get it to work. Except for once.... It was blowing out ice cold air and worked fine until I switched it to defrost. after that the compressor wouldn't come on and all I get is heat. Clearly I don't know what I am doing??? could someone enlighten me? do I need a dash control unit?
Thanks
