Sounds like the blend door actuator. It separates the driver and passenger side from getting air on the AZC system. Here are some instructions on replacing it:
The passenger side blend door actuator is used on all models equipped with Automatic Zone Control (AZC). This actuator is located on the front of the HVAC housing to the right of the floor panel transmission tunnel and cannot be removed from the passenger compartment without instrument panel or HVAC housing removal.

NOTE: This procedure is for AZC Systems (Passenger side only).

  1. Disconnect and isolate the battery negative cable.
  2. Remove the glove box door. See: Body and Frame\Interior Moulding / Trim
  3. Remove the lower I/P glove box door surround panel.
  4. Remove the dash assembly. See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Instrument Panel Assembly
  5. Remove the HVAC assembly. See: Housing Assembly HVAC\Service and Repair
  6. Unplug the wire harness connector from the blend door actuator.
  7. Remove the 2 screws that secure the blend door actuator to the HVAC housing.
  8. Remove the blend door actuator from the HVAC housing.
INSTALLATION - AZC (Passenger side only)

  1. In stall the blend door actuator on the HVAC housing and tighten the two mounting screws to 2.2 Nm (20 in. lbs.).
  2. Plug in the wire harness connector to the blend door actuator.
  3. In stall the HVAC unit into the vehicle. See: Housing Assembly HVAC\Service and Repair
  4. Install the instrument panel assembly into the vehicle. See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Instrument Panel Assembly
  5. Evacuate the HVAC system.
  6. Recharge the HVAC system.
  7. Connect and the battery negative cable.

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.

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.

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 .

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.

I would say the alternator. The fluctuations when it is running indicate that the regulator inside the alternator is worn out. The overheating is probably because the cooling fan is not running fast enough or at all.

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?

it is as hard as it looks, the book says to take it to the dealer,

2000 Jeep Grand... | Answered on Nov 30, 2017 | 126 views

it could be a problem with the wiring with the sensor. You would need a multi-meter to check the wiring. Diagnostics cannot tell if the sensor is bad, only that the information sent does not agree with what should be reported.

when did it make the clicking. was it when turning sharp, if not it is another issue

2000 Jeep Grand... | Answered on Nov 19, 2017 | 53 views

back firing ( explosions in the exhaust) can be from fuel mixture too rich and unburnt fuel is getting to the hot exhaust
possible causes for that are excessive fuel pressure , leaking injectors ,leaking injector seals
backfiring through the inlet manifold can be calve timing, ---cam advance servo-- valve staying open ---valve clearance , problem hydraulic cam follower , incorrect firing order for the plug wires, crank/cam position sensors or wiring

Stop leak can cause the radiator ports to get clogged. But if your car isn't getting heat, it's probably your heater core. The heater core is usually burried in the firewall between the engine and where you or your passenger put your feet

not sure what type vehicle we're talking about here, although you can lube up the rack and pinion or grease up your upper, if so equipped, and lower ball joints.
