The ignition module is located underneath the distributor cap, while the ignition coil is mounted typically on the engine block on the same side about 6-9" away. The center spark plug wire will lead to the coil. The module can be found by removing the distributor cap, there is a wiring harness that plugs into it.

Does the noise sound as though it is coming from either the front or rear axle and does the noise change as your speed increases. If so it sound as though your axle is whining requiring overhauled if really bad.Common problem

long answer but should get you solved.

You know for some reason jeep eliminated the FC relay for some models and now relies on the computer to determine when and at what speed the fan should run based on coolant temperature inputs and A/C compressor status. If the fan is not working properly i would consider replacing the fan,
"I have a 04 GC also with the 4.0 and I could not find my FC relay either. Nobody at a local dealer here had ever heard of this phantom FC relay problem. I was able to find an electrical diagram on the web that does not show the FC relay for the 04 GC but that was it. The diagram only showed the PCM and two relays in the PDC near the battery. My GC was overheating now and then. It would seem to overheat when you were in stop and go traffic or letting it idle. I was not losing any coolant so I replaced the thermostat but that did not fix it. After much frustration I started the engine and sat there and watched it run until it began overheating. I paid particular attention to the fan. When the engine began to overheat the fan was barely spinning and would even shut off at times during the overheating. I knew this was not right so that is when I began this search for the FC relay but I could not find it. I disconnected the fan and did some checking on the two speed electric radiator fan. It has a 3 pin connector where the center pin is ground. When I ran power to one pin and grounded the center pin the fan would run. However when I switched the power to the other pin I got nothing. I had already checked operation of the Low and High Speed relays in the PDC near the battery and all checked out so I went and picked up a new radiator fan assembly and installed it. That was yesterday and that fixed the overheating problem. I have concluded that for some reason jeep eliminated the FC relay for some models and now relies on the computer to determine when and at what speed the fan should run based on coolant temperature inputs and A/C compressor status. I also found out that although my GC does not have the towing package it does have the max cooling package. When I went looking for a new motor for the radiator fan at local auto parts store I was asked if it had the towing package and I answered no. Everytime I did they would bring out a motor that only had a 2 pin connector. Not one of them kept the motor that would be needed if you had the towing package. I bet if they did it would have a 3 pin connector on it. So while my GC does not have the towing package I think it has the max cooling package that usually comes with the towing package. I think the standard cooling package uses a one speed fan where the max cooling package uses a two speed fan. It may be that the standard cooling package uses the FC relay which is supposed to be under the passenger headlight but the max cooling package eliminates the relay and uses the PCM to control two relays in the PDC which in turn run the fan. One more thing....replacing the radiator fan assembly involves removing the shroud. One of the 4 screws that holds the shroud is in a very tight space. I fianlly got to it with a long socket extension and swivel. I know this is long but I hope it helps because I was very frustrated at the lack of informartion available locally and on the web in reference to this oddity" (article found on web)

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

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.

Did you replace the thermostat also?

2000 Jeep Grand... • Answered on Mar 09, 2019


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....

2000 Jeep Grand... • Answered on Sep 30, 2018


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.
