I have a 99 Tahoe, which i then replaced a burnt up ac compressor 3 times due from staying running the whole time the truck is running whether the controls was off or on, so after the second time i pulled the controls out the dash to see a burnt diode, so i got another control cluster and bam ac is working on/off by controls a day later compressor running all the time again, remove the controls again and the same diode is burn again what is going on
