Скачать или смотреть Toyota Corolla E 111. Hidden Aircon compressor Relay and Fuse Box, Shorted AC clutch magnet

Cabin fan blower , radiator fan
and AC condenser fan and AC Compressor electro-magnet clutch,.
have individual Fuses and Relays. And one of these 3 fuse boxes is hidden !

At first I got confused because my cabin fan is working, but the Aircon Compressor is not engaging.

first step was to check Refrigerant pressure. it's ok, then next step check visible Fuses and relays, all good. then test voltage at feed wire to AC compressor - NONE !

isolate defect by running a direct feed wire + to the compressor; clutch engages and wire heats up. Compressor Electro-magnet clutch -. should be good ?

not sooo fast !!!!!!


Then research to find that there is another "hidden". Fuse Box with relay dedicated only to the AC compressor and Condenser fan ! Its located and hidden behind the kick panel of front passenger !
( beneath and side of glove box. )

I Changed 15 Amp fuse. I thought all was well, but the 15 Amp fuse blew again !

I disconnected the AC feed wire and ran the AC compressor switch to turn on.
This time the fuse did not burn !

So I returned to the AC compressor clutch as main suspect for blowing fuses.

Then I removed the AC Compressor Clutch and Electro- Magnet. It was burned and shorted.

note: the continuity of the elecro-magnet is tpresent, - whether burned or good. in my case, I could not find the difference, they are shorted, whether good or bad, in my case.

AC repair is challenging !

this is my lesson with Corolla Aircon compressor problems. I hope this helps you.
