How did you hook up the inline fuse to compressor and ground to compress ? Ground what ? Right at the clutch coil ? You have to be hooking it up wrong . The compressor can't cause the clutch coil to short or blow the fuse , even if the compressor were seized up . An before that would have the serpentine belt would burn up , squealing noise. applying B+ voltage in the relay socket ,pin 30 to pin 87 will engage the compressor clutch . If the fuse blows the wiring from the relay to the compressor clutch is shorted to ground . Look for rubbed through wiring harness .
If the fuse blows, unplug the compressor wire to the clutch and replace the fuse and try again. If the fuse doesn't blow, the compressor is the problem. If the fuse blows suspect a direct short in the wiring from the relay to the compressor
Possible direct short in compressor clutch. Disconnect wiring harness from compressor and then turn AC on> If fuse doesn't blow, then problem is in compressor/clutch. Suspect it to be seized. If fuse blows while compressor disconnected then problem in wiring.
Most likely the clutch on your ac compressor has stopped working or the entire compressor has seized. The blower will still work, but without the clutch working correctly int won't cool like it should. While possible to replace just the clutch on a compressor, it's generally better to replace the entire assembly.
Let's break this down.
1 Does the fuse blow when the heater is on, or just the AC?
Yes- Fan motor problem likely need new blower motor.
2 Disconnect the AC compressor clutch wire. Remove the blown AC fuse, connect a multimeter across the sockets for the fuse, measure DC voltage across the two sockets with the AC switch, and Ignition switch ON. Is Battery voltage present?
Yes- The wiring harness has a short between the output of the AC switch and ground, likely a pinched harness.
No- The AC compressor clutch is shorted. Replace either the whole compressor or the clutch.
CHECK AC COMPRESSOR CLUTCH COIL WIRE CONNECTOR HOOK UP.IF AC COMPRESSOR CLUTCH COIL WIRE CONNECTOR HOOK UP WRONG OR WIRE HAS A SHORT IT WILL BLOW THE ECM FUSE AND AC COMPRESSOR FUSE.CHECK FUSES AND AC COMPRESSOR WIRES.
Unplug the a/c compressor, there will be a plug near the pulley. Install a new fuse. Start the vehicle and turn the a/c on. Wait about the same amount of time it took for the fuse to blow in the past. Did the cues blow?
If no replace the a/c compressor, the clutch has gone bad.
If yes, than the wiring between the fuse and the relay or the relay to the comps sore is grounded. A careful inspection of the wiring should reveal the problem.
