Jeep J20 - Popular Questions, Answers, Tips & Manuals

The quickest way to repair the problem is unplug the plug from the headlight. Then hook up a test light turn lights on.Find your low beam wire. then turn your hi beams on and find that wire. Run the left over or 3rd wire to ground on (body engine or what ever good ground you can find) that should fix the problem.

Sounds like you have a bad earth.

no year car. ? 1971 to 1988? J20\ that must have been some bump, huh? google image searches find 1000's of 360cu-in blocks here is one, and the dip stick is seen. http://www.hotrod.com/techarticles/engine/hrdp_0804_small_block_mopar_engine/photo_01.html

what contact what year. name it exactly..... lots of parts on car. and is this a STALLS post?

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????6

Check the ignition fuse and the ballast resisitor. Most Jeeps had these on the firewall. Looks like a
square knife sharpening stone about 3" long with electrical connectors on each end.
Just replace it, they are cheap. Check with Oreilly's or Autozone for info on the location
of any ignition fuseable links. These are inline fuses that are sealed in a wiring harness
or simply look like a plastic nub in the middle of a wire.

According to some old production records (from derek Redmond), your serial number corresponds to december 1963

The solonoid is sticking, either have repaired or replace starter

Hi,

A very common problem in 1999-2004 model Grand Cherokees has been weak blend and recirculation doors in the HVAC systems. The doors are turned by a motor attached to the bottom of the door at the end of a hinge shaft. The motor stops turning when there is enough physical resistance from the door stopping against its housing. This puts stress on the shaft/door junction and over time strips the shaft so that it spins almost independently of the door. The motor then experiences little resistance and keeps turning, which sends the "travel too large" code.

In January of 2004 Jeep issued an informational TSB (#24-001-04) which introduced newly designed sub assemblies. The newly revised assemblies have stop tabs that stop the motor from turning, instead of relying on the weak shaft/door contact. It is recommended that the respective sub-assembly be installed if a blend air door(s), a recirculation door, a door link, or a sub-assembly housing requires replacement. The table below provides the part numbers for the new HVAC sub-assemblies.

Most common failures - The most common failures will require the replacement of the HVAC sub assemblies. This requires removal of the entire instrument panel assembly, a very involved process.

Least common failures - The least common failures are the door actuator motors. These should be checked first as they are the easist to replace (with one exception). The single motor for the Manual A/C system can be accessed and replaced by simply removing the glove box. The Auto AZC system uses 2 actuators. Only the drivers side actuator can be accessed from behind the glove box. If you are getting cold air/no heat on the drivers side only, there is a chance that drivers side actuator could be defective. If you have cold air/no heat on the passenger side, the actuator that controls this side requires removal of the entire dash and HVAC assembly.

Hi,
I think I know what your talking about... you can find the switch to for your head lights. But even when the switch is off ... your head lights are still on.
If that's what you mean then just put your parking brake on one small click and your head lights should go out.
If that isn't what your talking about please contact me .

My truck was doing the same thing.... replaced the crankshaft sensor first, truck would still die after about 10 minutes of idleing, it back-fired thru the engine and blew off the back of the intake manifold. Pulled the monifold, reglued end-cap and put back in truck. STILL died after idleing for 10 minutes. Code PO320 kept coming up ( crankshaft sensor) researched it and found a bad camshaft sensor can cause crankshaft sensor to act up and give code for the crankshaft sensor. Replaced camshaft sensor and the truck runs like a dream !!!!!! I believe the Manifold was cracked for a while causing the 1299 code reading ( vacuum leak) the back-fire finished it off! I would check the back of your intake manifold for a leak. The combination of fixing the vacuum leak , cam/crankshaft sensors seems to have fixed the problem. GOOD LUCK!!!

Whew! Tight spot. Here are some quick and some more involved things to check. Hopefully, another responder will pitch in. A good time to call AAA. Troubleshoot this issue step by step: Check for Spark: Crank the engine and check if there's a spark at the spark plugs or ignition coil. If you have a spark, the crankshaft position sensor (CPS) is likely not the problem. Fuel Pump Operation: When you turn the key to the "on" position (but not start), you should hear the fuel pump run for a couple of seconds. If you don't hear it, there might be an issue with the fuel pump or its relay. ASD Relay: The Automatic Shutdown (ASD) relay controls power to essential components like the ignition coils. If the ASD relay is faulty, you won't get spark. Check and replace it if necessary. Throttle Position Sensor (TPS) and Intake Air Temperature (IAT) Sensor: Ensure that these sensors are functioning correctly. They play a crucial role in engine performance. Check the Key: If everything else checks out, consider the key itself. The chip in the key has a unique identifier code. Some replacement keys may mimic this code, so make sure your key is genuin.. Bus Line and SKIM Module: Verify the PCI bus line between the PCM/data link connector and the SKIM module. If there's an issue with communication, it could prevent the engine from starting

old fords have them and yours does tomine not. ,not my JK Nor wk. I have your real factory service manual here on screen 2. yes, replacing the alternator with the battery connected does blow a fuse. in 1 nano second fast. BOOM , let the smoke out. but saved by the link. OKAY you were right the liberty has that link you were right, it has links ! this is your actual car, wiringi have it all there. FSM PDF real.

This might sound silly but have you checked the switches on the actual light fittings? They usually have three settings. Permanently Off, door controlled or permanently On. If there are no switches on the actual light fitting try pushing the lens itself at each narrow end. Some lenses rock end to end as the switch mechanism.

It is a known issue.

1. Faulty Instrument Cluster: The instrument cluster itself may be defective or damaged. Over time, electronic components can degrade, leading to malfunctions.
2. Fuse: Check the fuse box for any blown fuses related to the instrument cluster. A blown fuse could disrupt power to the cluster, causing all the gauges to fail simultaneously.
3. Faulty Wiring: There could be a problem with the wiring harness or connectors that supply power and data to the instrument cluster. Loose connections or damaged wires can prevent the cluster from receiving the necessary signals.
4. Vehicle Speed Sensor: The vehicle speed sensor (VSS) is responsible for providing speed data to the instrument cluster. If the VSS malfunctions, it can cause the speedometer to stop working, and it may affect other gauges as well.
5. Engine Control Module (ECM): The ECM communicates with the instrument cluster to provide data for various gauges. A malfunctioning ECM could disrupt communication and cause all the gauges to fail.
6. Grounding Issues: Poor grounding can lead to electrical problems, including instrument cluster malfunctions. Ensure that all ground connections related to the instrument cluster are clean and secure.

Given the complexity of diagnosing electrical issues, it's advisable to have a qualified mechanic or automotive technician inspect your vehicle. They can use diagnostic tools to pinpoint the exact cause of the problem and recommend the necessary repairs. Additionally, if the issue is related to the instrument cluster itself, it may need to be repaired or replaced by a professional.

a hose clamp ?or just guide clamp to the fan shroud.jeep dot com will have it on all jeep web sites, under title cooling systemgood luck, not the 2.4L ESS engine right:2.4L gas as seen on mopar.com sitenow I will read the pages online to youguessing all that. stuffi go to mopar.comand see this. is this a match.if not go there and find it or as them over the counter jeep dealer.or go there, and put you VIN in the boxand find the parts, no better way exists.

First you will need to determine if there is a problem with the electrical system or fuel system. Connect a fuel pressure gauge to the fuel rail to see if you have pressure when the vehicle dies. It it maintains pressure and the vehicle dies, then check to see if there is a spark issue. Fuel issue could be bad/weak fuel pump, bad relay or restriction in fuel delivery system. No spark could be ignition coil, bad computer, bad electrical connection or relay. To check these systems you need special meters and scanners. Best to take to a repair center.
