No one can guess for you

You have to check for OBD Codes &
use factory trouble charts, to diagnose
that module & find a problem

Sounds like the same problem I had. I brought it to the Jeep dealer and they told me that the heating element in the seat stopped working. They told me that the only way to repair was to take the seat apart and replace the heating element in the seat. Of course they will charge you the standard $80 to tell you this. and then quote you $500 plus to repair. I can't even remember how much, I have decided it was not worth it.

possible that the ball size is wrong for the tow hitches
they do come in two sizes and there is just enough difference to allow movement at the ball

Get your hands on a shop manual. We're not going to make a video for you.

There are plastic rivets taht need to be pull and possibly to be cut. and there should have 2-3 bolts per side which need to be removed. The rivets or clips can be purchase at the dealer or local Automotive store, such as autozone and etc.

Check rubber brake hose at caliper and replace if defective.

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.
Hope it helps! If you need more, just send me an email at familyguy77351 at yah I wil be glad to finish helping you with more detail.

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

EVEN IF YOU SWAPPED THE PCM IT HAS TO BE REPROGRAMMED TO RECOGNIZE YOUR KEYS. WHEN A READER WONT CONNECT IT IS EITHER A FUSE IS BLOWN OR ONE OF THE SENSORS IS SHORTED TO GROUND CAUSING THE FAULT

Jeep Grand... | Answered on Oct 19, 2019


These conditions MUST be ruled out entirely.
Check for any of the following conditions/mechanical problems.
AIR INDUCTION SYSTEM - must be free from leaks
ENGINE VACUUM - must be at least 13 inches in neutral
ENGINE VALVE TIMING - must be within specifications
ENGINE COMPRESSION - must be within specifications
ENGINE EXHAUST SYSTEM - must be free of any restrictions or leaks
ENGINE PCV SYSTEM - must flow freely
TORQUE CONVERTER STALL SPEED - must be within specifications
POWER BRAKE BOOSTER - no internal vacuum leaks
FUEL - must be free of contamination
FUEL INJECTOR - plugged or restricted injector; control wire not connected to correct injector.

Unfortunatly, a scan tool will be required to monitor o2 sensor voltages while the engine is running in closed loop. This code you are displaying is NOT an easy solution to trace down. I expect you had an exhaust leak and is why the cats were replaced? Anyway, if so, the PCM can reset the light after a few GOOD trip readings occur that will satisfy the PCM's no fault signal, otherwise the JEEP dealer is going to be your only solution and a pressure test should be performed.

when you check fuses you must use a continuity tester or a volt meter to verify they are indeed not blown also clean the contacts in the sockets and your turn signal switch may be finished and needs replacement your vehicle is now 17-18 years old by manufacturer date sticker so things fail after almost 20 years there could also be a broken wire on that socket but verify fuses so you can eliminate that cause sometimes they look good but are blown out in the corner at the top ok

I suggtes check in the Service Manual, in this link... Secc-7-Cooling-System

If the hoses are news, then its possible that your problem may be in the metallic coupling (lower radiator).

Tell us news.

This could be a loose fuse or a bad connector or the fan switch bad wire also but check this out if it's a lever or twist knob switch see if it has looseness in it does the lever move side to side or its not locking in position EX. LOW-MED-HIGH if so then when your hitting bumps the contacts in that switch disconnect and the fan stops working the air bag warning light is on the same circuit probably so there's a loss off either power or the ground and that makes the light come on next there is also a blower motor control module resistor that controls the heater/ac fan under the hood at the fan motor case check that connector and wires try wiggling it and see if you hear the fan stop these are a common problem for 3 reasons (1) mechanics trying to axcess the area can put pressure on this unit trying to get there arms in deep causing the plug to break or a solder joint to break on the circuit board inside it (2) this also can happen from pulling on it to unplug it or reconnecting it to much force on it (3) a wire on it was punctured to test or get power and not sealed causing corrosion to eat part of the wire so intermittent voltage is getting through and as the wire heats up it can't arc and the power break open circuit happens if you can take out the blower motor resistor and if it's abe to be taken apart (release tabs) only don't try to open a completely sealed unit water will get in it and more problems will come anyway if you can open it inspect the circuit board for solder joint breaks where the connector pins are on the board this is a very common problem and a quick resoldering will fix it but also check the whole board a bad soldering joint will show a circle on it in a ripple kind of appearance or just not enough solder on the pins on the connector part or a resistor capacitor inside okay so if you can check it out inside also if the plug connector looks burnt on the face that plugs into the module then there is definitely a problem there with the module or the inside of the plug is broken and wire separation from each other is lost causing wires that shouldn't make contact with each other to arc grounding out but this would most likely blow a fuse but is possible if only a tiny bit of contact happens so what I've explained to you here is definitely your problem you have to investigate and go through the process of eliminating possible causes okay but I would lean more towards the blower motor resistor/plug or a loose fuse in the fuse box obviously I'm not there to check myself and if your truck was worked on recently and this started go to that resistor ok and so you know where this info is coming from I'm a taxi mechanic in nyc.with 50 + years of experience and I've seen a ton of blower motor resistors that have broken solder/plugs causing this problem on/off/on/off from bumpy streets good luck stephen

Wheel sensors are usually for ABS and traction control systems. Speedo is usually connected to transmission

Check the wires that run through the door pillar they do break in time as door opened repeatedly .

2001 Jeep Grand... | Answered on Sep 21, 2019


Does the vehicle stall? Is this code intermittent (goes away)?
If so, a cheap test, possible fix is the MAP sensor. To be sure, look at the freeze frame data and look at the manifold pressure itself. If manifold pressure suddenly jumps to near atmospheric pressure (i.e. zero vacuum while under part throttle load) replace the sensor.
