Basic cooling fan questions (pic and questions)
I figured I would start working on the cooling fan issue with our 95 sc. The previous owner wired a switch in and put the switch under the hood... (shown below)
We need to open the hood and turn the fan on before driving the car to keep it cool.
To debug (or try to fix) the problem - I reconnected the cut wire from the switch and "jumped" it back to itself (pic below) - this was done by crimping a pices of 12 guage yellow wire to the cut red/black wire that was rigged up to the switch above. Picture of the reconnected wire below.
The picture below shows a better view of the patched in wire..
Now - before we did anything we flushed and filled the cooling system yesterday and replaced all the belts and even both drivers door hinge pins and bushings (that has nothing to do with the fan though).
I also replaced the ETC sensor figuring that is maybe why the fan was'nt working in the first place which leads to why I reconnected the wires back together to see if the fan would go on by itself -
HERE IS WHAT HAPPENED TO OUR TEST.
Started the car up and let it idle for about 20 minutes to see if the car would get hot enough to cycle on the fan - during this test - the temp guage went up to the 'L' on normal and the fan never came on However after the car was idling for several minutes and the temp was on the N in normal we turned on the ac to max ac - the fan did come on but only at low speed - when we shut off the max ac the fan did not turn of but stayed running at low speed - we shut the car off the stop everything and shut off the ac too. We restarted the car and turned on the max ac again - this time the fan did not turn on at all. we also let the temp build up to L on normal again and no fan - getting nervous about overheating we shut off the car.
I hop someone out there can give us enough pointers to help us get the fan(s) working. The small fan in the front of the condenser never came on either....
Thanks in advance
sincerely
