Okay I fixed the turn signals the fuse fell out. Still can't figure out the other problem when I go to shut it off it wants to start again. Also on start up after sitting for a while it hesitates but if I let it sit a minute then start it again it'll be fine. I was told fuel filter could use a new one but I don't think that's it. Again any help would be greatly appreciated.

Should you change it just cuz? Sure.
Question. My 1999 Cherokee I6 Automatic. I have new radiator. Water Pump maybe 5000 miles ago. I have three electric fans across the back of radiator. Today on a mild trail ride I started heating up. Got up to 240 degrees. I turned around and headed down the canyon and back to my shop. Temp calmly went down to 208. Got on freeway at 70mph and I was running about 215 which is okay. It has done this before. I'm thinking I need a new theromstat. I don't know when or what thermostat is in there. Can't think of anything else that would cause my problem. What do you think. RSWiser
Went for the same trail ride this afternoon.
I didn't get as hot but I did get hot. (According to my Ultra Gauage).
My dash gauge showed 210 most of the time. They when I started up the dirt road, climbing but not hard, the dash gauge climbed to the next tic after 210. No where near overheating.
While I was 1 tic over 210 on the dash gauge, my Ultra Gauge go to 238 degrees. I presume it reads from the same sensor and the dash gauge.
How hot is to hot? Any where does your cherokee run on the dash gauge when out on the trail.
Thanks,

Yesterday I replaced the thermostat with an OEM.

I'm wondering if the guy who did my radiator change did a 50/50 mix. Could straight Anti Freeze cause this?
When out on a slow strain ride where how hot does your cherokee run?

Radiator was installed new a few months ago. When I replaced the thermostat I topped it off and with a 50/50 mix and burped the system for 30 minutes.

I'd bet money on that if you only have trouble at low speed and not above 15mph. You may want to try some sort of fan shroud (even if it's cardboard for now) to see if that helps.
One other thing I just thought about:
If it only does it at low speed (below 15mph), there is another possibility. If it does it while crawling but NOT while idling, it could be your transmission fluid heating up and causing cooling problems where it intertwines in the radiator. If that's the case, and external transmission cooler may solve it. I haven't seen this happen before, but I suppose it's possible.
