My A/C compressor won't start. All fuses are good. I have switched all relays around hoping to move problem. No luck. I don't get any voltage at the compressor connector. Not sure if I may have a bad wire or connection. Need either wire diagram or tech. help. Also need to know which relay turns this on. Owner manual doesn't give any info on which relay is for what. Any help would be great!!! I have 170000 kms on car so warr. is long gone. Thank-you
