I own a 2003 Saturn Ion I.
Recently I noticed that the fan on the radiator does not function, resulting in overheating when using the AC. I have tested the electrical wire leading into the fan motor and found that it is putting out 14.4 volts, indicating that the wire is functioning properly and that all fuses are intact. I also hand spun the fan to see if it would turn without resistance, which it did, indicating that the motor is not jammed.
These tests lead me to believe that I may need to purchase a new fan unit and install it. My local sleeze shop wants $250 to do it, however I have found I could do it myself for $70 and an hour or two of my time, much more efficient.
I would like to know if my assessment of the situation is correct, and if I should go ahead with purchasing and replacing the fan? Additionally I have found that there is a dual fan option for my vehicle, and I was wondering if I should purchase that instead of the standard one fan?
