Help! Frustrated

I took my jeep to work (I drive a bus) and the mechanics there said they would find out if my temp light worked or not. They took the dash off,and replaced the coolant temp sensor and now my jeep is F!?#?! up. Now the coolant fan is never off, from the moment I start my jeep it stays on, it floods when I start her, I can go down the 25 mph roads here without even pushing the accelerator. He says the sensor has nothing to do with the fan staying on and some other side of the road mechanic I pulled into says the trouble with it starting like it is flooded is not related the them replacing the sensor and the fan staying on. They talk to me like a dumb blonde. Please post something I can put in front of their face to show them it is a sensor that can affect alot of things and bypassing the wires to make fan stay on can cause this. Am I losing my mind because I am seeing sites that tell me differently. Thanks for any help.

If they replaced the sensor in the thermostat housing, they replaced the wrong sensor...it doesn't have anything to do with the light/gauge...and likely left it unplugged and/or with a poor connection. The sender for the dummy light is in the back of the head. The one in the t-stat housing is for the ECU. If that one is unplugged, the fan will run anytime the ignition is ON.

Another possibillty is that they uses the wrong sensor altogether. Then, if the ECU doesn't "see" the sensor, it will also turn the fan on constantly and the air/fuel mixture (based on the reading from the blind sensor) will be messed up. That's my take on it...I could be wrong. Don't throw this in the mechanics face, I'm not a mechanic. I'd just check it myself

Also a 96 Cherokee is NOT an FSJ.

The sensor in the t-stat housing was replaced and it is in there tight and I am assuming it is the right one- from car quest- and visually it looks like the right one. So could this be happening because of something in the dash they switched when testing the dummy light? Thanks for your info.
