A/C Fuse Blowing


Recommended Posts

Hi everyone im new to the forum.

The fuse for the air conditioning blows when the car is driven hard but is ok when driven easily and is the only fuse affected. Does anyone have any ideas to the cause please

I would check the wiring (1 wire) from the compressor to the car body to start with, he probably rubs against the car body or something when accelerating hard by the (too much?) tilting movement of the engine. If you can not find anything there, then check the wiring's, connectors and switches between engine and car body.

Is it the fuse for the blower fan? Inspect the blower motor for play in the rotor shaft. They can wear the bushings and under higher cornering load cause the load to increase in the motor and blow the fuse.

I agree about the blower motor problem,I have been replacing alot of those lately. Do you hear any squeeking noises with a/c operating?? Bushings get dry , dirty& worn. only permenant fix is replace the evap blower.
