'88 Eldorado - Blowing 15a A/c Fuse

I've A Brand New Harrison Compressor, New Fan Control Module, All Relays Test Good.

Help????

No Runs Fine

Is the fuse blowing since compressor and module replacement? What have you done to find the short. What other items are powered by this fuse?

Well, I have a 1977 Dodge van, and this sort of thing used to happen to me until I replaced the connectors in the power line to the A/C fan and the compressor.

You might try to feel the connections, especially in the fuse box to see if they're hot. I finally had to go to a junk yard and buy a handfull of the metal holders for the fuses themselves and had them replated. It works fine now. But for awhile I was trying to sand the tips of the wires at the holders and so on.

I have the same problem. '93 Sixty Special. I could more help on how to go about looking for the short. According to the manual only the AC is powered by this fuse.

A lot of different vehicles have a diode molded into the A/C clutch connector. If that diode fails shorted, it will blow the fuse in microseconds.

Simple test for a failed diode is remove clutch connector at compressor, install correct fuse, select A/C ON. If the fuse blows, it is most likely a failed diode.
