Neither of my radiator cooling fans are working. I recently replaced my crankshaft position sensor and both camshaft position sensors, but I didn't disconnect anything related to the cooling fans. I'm not getting any OBD codes and Check Engine light.
Radiator cooling fans stopped working
If you have no codes or CEL, maybe the car's not getting hot enough to need fans. Turn on the AC; fans come on by default with the AC. If fans run, you probably just have a defective engine coolant temperature sensor. If they don't, you have a blown fuse or relay, defective fan clutch or wiring, bad fan temperature switch, or bad fan motors.
Thank you, Ed92626. The fan does not run when I turn on the AC. I plan to test and possibly replace fan relay(s).
