2003 WJ, 4.0L engine
I'll save the long story and cut to the chase. I don't THINK my radiator fan is coming on at all. After driving to work today (30 miles of highway), I parked the Jeep, popped the hood, and looked at the fan. It was stationary.
I'm not having any overheating problems. This is just something I happened to notice. Granted, it was 49 degrees today and I was traveling at 60 mph. But the temp gauge read between ~180-200.
My question is simple. When is the fan suppose to run? Should it always be running (at least on low) when the engine is on? Or what are the conditions for it to run? I have a feeling the PWM needs to be replaced. But I've never had any overheating issues.
