My SUV is an XL. Overheating when parked and running but not when I drive for hours?

Good afternoon,

Are the cooling fans working when it is at idle? If they are not, it will overheat at idle and not at higher speeds.

Okay, do you have a voltmeter or test light to do some testing?

I attached a diagram of the system. Check the two fuses listed for power on both sides with the key on.

Sometime it says Stabilizer off, then overheats when parked.
