If this still fails to turn on the fan i suggest you turn off the engine for now and consider troubleshooting other aspects of the cooling fan electrical system including the low speed fan relay.

Bmw e36 auxiliary fan not working.

You might look into. I just tried my a c for the first time today and my auxiliary fan is not working so i guess i ll be checking mine out next week i know soon as i turned the a c on the 318 the fan would start right up. If so retry the test jumpering from terminal 30 to 87a. If the fan is not working yes if you idle for a long time it will get hotter.

Auxiliary fan not coming on. Bmw e36 m3 evolution. If you know for sure the fan is not working start there. Trace the harness and fix it or bypass it.

Replace the high speed relay. The fan should come on at high speed. If the fan does not run check for 12 volts at terminal 30 in the relay socket. You could also apply 12v to the fan itself to make sure it works.

You should be careful as the current draw is substantial. Go to my website and bmw forum. If the fan does not run on high speed check to see if your application is using a 5 pin relay. Go to my website and bmw forum.

If it does the fan motor is ok. Could be the fan could be the sensor. If the fan itself is the issue the part can be costly but the replacement is relatively straightforward so long as you re careful not to damage the delicate radiator fans. 04 20 2008 01 29 pm 14.
