Anytime I press the A/C switch it blows the 10 amp gauge fuse which protects that circuit along with several other circuits. As long as I do not engage the A/C switch the fuse does not blow.
Initially thought it was the compressor clutch drawing too many amps. Replaced the clutch but the fuse still blows. Then decided to replace the compressor with another used but working compressor and the same result. Replace it with a third compressor thinking the second one was bad as well and the same result occurred as well. Fuse blows every time the A/C switch is pressed.
What am I missing here? Is it the compressor still bad (doubtful at this point)? Is it the A/C switch itself? Is there an A/C cooling fan relay causing this? Or is it the A/C amplifier. I do not think the cooling fan relay for the condenser is on the same circuit as the 10 amp gauge and compressor are though but I could be wrong.
any help would be great. This has been plaguing me for months without a solution. Again the fuse only blows if I press the A/C switch. Does not blow otherwise. Has to be related to something in the HVAC.
have the same problem?
