92 Saturn Engine Cooling Fan

I am having a problem with the engine cooling fan on a 1992 Saturn SL2. The
fan works fine when the air conditioner is on, however the fan will not
switch on when the coolant gets hot (as reported by the temp guage). I
have already replaced the engine coolant temp switch and checked the relay
with no luck. I also have codes 26 and 32 stored on the PCM, but I'm not
sure if there is any connection. Thanks.

On a '92, there are two sensors. The single wire sensor is for the gauge, the
double wire sensor is for the PCM. Did you replace the correct one? Just
asking...

I had a 93, and the codes 26 and 32 were my EGR solenoid and valve. Also,
my cooling fan would not operate as well, the Saturn dealer had a look when
they replaced my EGR valve, and it simply was corrosion at the back of the
relay under the underhood fusepanel.

 

Where is the PCM?

Under the dash, between the steering column and driver's door.

 

I've been having problems with the cooling fan operation and it was
recommended that I clean the relay under the underhood fune panel. I'm
not quite sure how to remove the panel to get under it to access the
connectors. Any help would be appreciated.
