If you take the tail light assembly off and take the bulb out, you'll see three metal contacts on the tail light assembly.  Pry them up slightly and slide a small, folded piece of aluminum foil underneath it.  
Replace the bulb and try to reproduce the problem.  I found this fix online and did it to both sides of my car.. no problems since

Take some lube spray and spray the entire lock assemblies. You may need to take the door panels off to do a good job. With the panels off you can watch and see what is happening.

it is a sentry key light. which is part of the anti theft device for the ignition for the jeep

Did you replace the thermostat also?

You need to pressure test the cooling system. Unless you had the heads magnafluxed or inspected very carefully, there could be minute cracks causing the problem.

This is the #1 problem with any engine where boiling takes place due to the expansion power that steam has the capability of producing.

The cylinder walls could also have cracks in them, there could also be a freeze plug that is leaking slightly, causing the engine to overheat as it can't build the proper pressure.

sometimes it's a better move to get a low mileage used motor, than to attempt to repair one that has high mileage and this type of suspected damage.

good luck

Since you have already changed everything that you have, I can not think of anything new that might cause your Jeep to overheat. Are you going by the meter in your vehicle or doing separate temperature measurements? I had a defective temperature gauge that caused me to chase my tail till I did separate measurements.

Are you sure the radiator fan is kicking on?

That vehicle has a known problem with fan relays....

The smell is way to much fuel in the exhaust and the catalytic converter is overwhelmed, it will overheat and quite possibly start the truck on fire if you don't fix the over fueling problem.

grab a hanes book my bumper on mine flung off like sling shot on my 96 it had plastic pegs held it on see if yours the same get the hanes book it helpfull

Try squeezing as you pull, be gentle

I have seen jeep TPS - throttle position sensors cause a surge like you describe , but not with injector circuit code's . The PCM - engine computer controls the injectors by supplying a PWM - pulse width modulation ground . Checking the electrical circuits for those injector's would be the thing to do . Do you know how to test electrical circuit's ? Plus checking the drivers (transistors ) inside the PCM should be done . Could be a wiring or computer problem or even those injectors could be failing . How to Check Fuel Injector Resistance with Multimeter How to test fuel injector circuit with basic tools open control wire

Rather then guessing an just replacing parts , have a qualified repair shop hook up A/C manifold gauges an check the system . Can tell you what's wrong in just min. (it is only blowing slightly cool air. I suspect it is the orifice/expansion tube and want to know if I can change it out myself or reair it.) Don't suspect , that's guessing . test don't guess . Are the A/C pipes going in through the fire wall cold ,have ice on them when A/C is on ?

You probably have a poor earth on a rear light cluster, if you can find the earth wire ( often goes to the body close to the lamp) that will be the problem and it will need cleaning or a new terminal putting on.

HI my name is Elizabeth and a lot of problems with a Jeep Grand Cherokee 97 \\\\\\\\\\\\\\\\\\6 cylinder 4x4 First the mecanic said it was the fuel pump and a sensor it worked for a days or so then it started dieing again on the road now he says its the pc \please Help

Your only problem friend, is the temperature sending unit/sensor. Upon cold start, this sensor wil tell the computer to go into cold start mode putting a bit more fuel in and raising the idle a bit to keep it running when cold without using the throttle. Replace that sensor and your good to go. Makes sense, right?

You just go to the link I attached I'm sure you will get the solution of your problem 2000 Jeep Grand Cherokee

This sounds like a bad or intermittent flasher relay. The Hazzards actually use a different circuit.
