Radiator Fan on High, 5KS
Dear Fellow Q-listers,
I suspect my radiator fan runs only on high speed and need help in
diagnosing the problem. It has run this way since I bought the car nearly
six years ago, so I always assumed it was a single speed unit, until
reading recent posts on this subject. (See Sandy Duffy's post, Nov. 27.)
The fan cycles off and on normally re: engine temperature, but only at what
I think is high speed. I've found the resistor, a large blue metal plate
with three wires behind the driver's side headlight.
My Big Question...how can I tell if this resistor is bad, and causing the
fan to run on only one speed?
I checked resistance between all three terminals and measured 0 ohms. I
admit to being an amateur, but something tells me there should be
resistance somewhere here.
Do I need to replace this item? How can I tell for sure?
Blaufergnugen wants $89 for it, BTW.
FWIW, shortly after buying the car, on the first warm day, I became alarmed
by the radiator fan's operation and took it to the local dealer to have it
checked out. They said it was normal. I've since learned the hard way not
to go to that particular dealership when I want help with auto repair.
Thanks for any help, and Happy New Year to all.
