Electric fan

[BmWwHiPPin]

does anyone know if you are able to buy just the electric fan sensor or do you have to buy the whole new fan.....i think that is what the fan is called it is the fan behind the radiator... thanks!

make sure its not the dual temp switch on the passenger side of the radiator. mine didn't work for the longest time and that was the reason.

are you talking about the sensor that turns the fan on and off?? you can replace just that because mine was dead and the fan was always on.

i replaced the radiator, thermostat, hoses, gaskets, etc. and still the car is overheating...i noticed the fan wasnt turning on..so i checked the fuses and they were ok. I removed the fan once again. I checked the fan motor and i saw a pipe like part where the cables from the fan motor go into and it seemed it had sand inside. i dont know the function of this part, so if someone can enlight me on this. After reading this post i am wondering if my problem is the sensor you have mentioned.

are there any tricks i could try, so i can rule out the fan motor...maybe connecting it directly to a battery and see if it works maybe?

at this rate...it seems i am going to have to replace everything! lol

Isn't there some resistor that is known to blow?

Up a little late, eh? :wink:

I was doing everything I could to prevent the spins.

Been there, done it!!

Dual temperature sensor can be changed and the tube like thing attached to the fan by two wires is actually the low speed resistor known to fail. I substituted this for an E46 blower motor resistor. This has various tappings so you can actually set the low fan speed! It's been working fine for close to 2 years now! Good luck

So i'm new to the Ti forums and sorry i don't actually have a Ti, however i have a 95 Is, and i'm having issues with my electric fan.

after posting around on BF's.......

i found out that apparently the Ti's have an issue with the Low speed resistor on the fan too, looking for any fixes, and please realize i'm ok mechanically, but not by any stretch of the means a mechanic or electrician, so looking for some lamens terms help.

thanks guys!
