Desert Driver Posted November 16 Report Share Posted November 16 Beyond baffling on my '84. With the key in the IGN position (engine not running), the evaporator blower and radiator fan run when I turn on the AC. However, once the engine is started the 30a fuse blows after approx 4-5 seconds. All electrical connections to the Delphi compressor have been pulled. I've gone thru at least eight new fuses trying to figure out what's going on. Any suggestions? (the thermostatically controlled electric radiator fan is fused separately and functions properly) Link to comment Share on other sites More sharing options...
ronmanfredi Posted November 16 Report Share Posted November 16 Is there a pressure switch at the receiver dryer or in one of the refrigerant lines somewhere? If so, disconnect it and see if that stops the problem. If the carburetor has an idle control solenoid to raise the idle when the compressor is on, then disconnect it and check also.

Desert Driver Posted November 16 Author Report Share Posted November 16 Worth a shot, so I'll try both suggestions. However I wouldn't think a pressure switch and idle solenoid would cause the fuse to blow. 🙃 Thx Link to comment Share on other sites More sharing options...
