My turn for an overheating problem!
Cranked the jeep this morning let it warm up like always. Let it run maybe 5-6 mins. Got in and cool air was blowing out of the vents with the heat on. Also noticed it was getting a tad above 200 degrees, which is normal once I'm on the road, but not when it's only been running a few minutes!
After I got on the road hot air started coming out. As I got close to work I noticed the temp hand slowly moving over to 260. It would get to the red and then go back over toward 200. Did this a few times.
I'll let it sit all weekend and work on it Monday. Sound like a stuck thermostat?
