Engine Cooling problem
1999 Saturn SC1 4 cyl Front Wheel Drive Automatic
The car overheats when at a idle. I replaced the heater hoses, and noticed the cooling fan was worn also. I checked the fuses and noticed the A.C. And the cooling fan have the same numbered relays. I pulled the ac relay, and the A.C. Shut off. So I switched the A.C. Relay with the coolong fan relay and the fan still doesn't work.
Now before the fan would not come on unless the A.C. Was on. After replacing the fan, it won't come on at all. I even ran 12volt directly to the fan and it came on, so the new fan is at lease working.
I called the auto store search for a possible sensor that might be causing the problem, but they said there isn't any sensor for the cooling fan. Is this true? And what should I do from here?
Day2: Now also the cars wont start. Not getting spark. Also the chime and all the dash lights went out. Checked the wiring, seems good. About 4hrs later the car lights, radio, and chime all started working. Then the car started. This is def electrical. What device would link all these devices together? (Mechanical/Drivetrain control module)?
Thank you for you time and effort.
