Question: Engine Cooling Fan on a 95 Saturn
Ok...let me start of by saying hEy! I've been browsing these forums for quite awhile (much longer before I registered), but unfortuneatly, not very smart about cars... Always amazing to read and see! Anyhow, I'm not sure if this question can be answered by anyone without a 95 Saturn, but maybe it's the same on a lot of cars? Anyway, here goes, and I appreciate you taking time to read this...and possibly help me!
I purchased a 1995 Saturn - SL2, and so...
When the original owner had it, he said that the engine cooling fan's "temperature sensor" stopped working (the fan would not come on), and so due to the fact it would be very expensive to fix, he installed a switch under the steering wheel to bypass it.
Now after reading the Hayne's manual I have, it says that "The engine cooling fan is controlled by the PCM (Power Control Module) and activated through a relay which is mounted on the left side of the engine compartment in the relay center. When the coolant reaches a predetermined temperature or the air conditioning system is turned on, the PCM closes the relay, completing the circuit. The PCM will also turn the fan off when the vehicle reaches a predetermined speed."
And now... I want to "understand" what's going on with it. He has two wires that I can see, going from the switch to the fuse box under the hood, one connecting to a metal bolt (grounding), and the second...went somewhere in the fuse box (it has been disconnected for awhile, and so the A/C is always on for this reason).
So I guess my questions are this:
-Looking at the fuse box, there are two things that are related to the engine cooling fan, a relay, and a large "30" fuse. Any clue which this wire should connect to? And/or how he is bypassing it period...
and the main question:
-Any idea what is "broken" and/or not working to automatically turn the fan on--or what I could check, to find out?
The motor for the engine cooling fan was just replaced, as well as the thermostat (unrelated, probably)...just thought I'd mention those.
Once again, sorry for making such a bothersome post on my first message here, and thank you very much for reading this far, and in advance for any possible help you might be!
