Top 20 2000 Jeep Cherokee - Page 8 Questions & Answers

Although the 4 cylinder is too underpowered to have air conditioning in my opinion, it still shouldn't overheat within 10 minutes unless something is wrong. If your Jeep doesn' not overheat when you are driving WITHOUT AC on then your compressor might have a problem and causing the engine to work too hard to turn it.

But if it overheats without the AC on, then the first thing you need to do is check the cooling fan and see if it operates! There has been a lot of problems with the cooling fan relay on this model. If that isn't it, then move to changing the thermostat and checking the water pump.

but is the fuel pump working.if you remove the air snorkel and spray intake cleaner into the intake while someone tries to start the car and it starts then you have a fuel problem.either the pump,plugged fuel filter,fuel injectors not working,dirt in the fuel system.check the fuel pressure if it doesn`t start when spraying cleaner into the intake.

comon problem was the fuel tank float.

You folks really need to learn to give more detailed info when you need help. The answer is, "it depends". If you have the small Cherokee, the answer is no. If you have the Grand Cherokee, the answer is yes. You will have to remove the motor and regulator to get them apart.

There are codes stored in the PCM. Go to an Auto Zone (or possibly other parts stores) and have them hook up a code reader. Its usually a free service.

Its not hard to replace, theres a bolt and nut on each end, remove them and out comes the shock, one end goes to the center link and the other end to the differentail housing on a bracket, it will take about 15 to 30 min to replace it, good day

In the Fuse Box, it is Fuse 2, 25A
I believe the Fuse Box is located under the dash/glove box.

I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514

it could be the (tps) throttle position sensor...

is it a single coil or a coil pack with all plug wires going to it..if its a coil pack its bad and the new one is no good ,that does happen alot more than u might think. i had a brand new MSD box bad from factory. and that was like 200 bucks so you never know. they have tests that u can do on the coil also to c if that is problem let me know if u want to go that way and i can help also

Possible bad TPS. Will it stay running if you play with the gas?

first you have to remove dead plugs on door handle and remove screws another screw on door opening handle and you have to disconnect 2 metal pins behind that and look all around the door panel sides and under should have several rivets make sure no any screw and rivets left on door panel pull door panel foward and pull it up dont go too hard dont damage door panel conections for proper reinstallation. before removing door panel from the door dont forget disconnect cable connections from window and door lock switches.good luck

I'm assuming the code that was pulled is P0305. Best case would be a bad spark plug on the number 5 cylinder. Keep in mind, the spark plugs are torque sensitive when installing. These are the possible causes that are stated in a Jeep service manual for your vehicle. Check the basics first......Camshaft,crankshaft,valve timing or vacuum problem,ignition coil output is low,engine internal mechanical problem,secondary ignition pattern is irregular, fuel contamination, Fuel pressure leak down is out of spec, fuel pump ampere out of spec, fuel pump capacity out of spec, fuel pressure is out of spec., engine compression, PVC system restriction, Fuel injector #5 is defective or the connection on the injector itself is loose or corroded, Intake gasket defective. It could also be freeze frame data in the PCM, but this is a very very rare cause.

I would recommend that you check the starter relay. It is not uncommon for these to go out. It is an easy fix, and does not cost a lot either.

There are two bolts if it is like the older model, you have to loosen the bolt on the front of the pulley and then the tension bolt. If you don't loosen the bolt on the front of the pulley the pulley can't move when you turn the adjuster bolt.

That's consistent with a signal switch (multi function switch) failure. It's part of the signal arm and isn't that difficult to replace. (covers on the column need to be removed). Instructions for that can be found in chilton or haynes manuals but if you have any mechanical aptitude you likely can just look at it and see how it comes out.

check the fuses located in passenger floorspace near center console. fuse cover panel should map out what fuse is what and you can test it once you find it y replacing it with a like-voltage or new fuse

you will need to have your transmission looked at. P0713 is a transmission fluid temp circuit high input, which means the fluid in the transmision was hot beyond limits and the other code P0731 was the first gear ratio incorrect. This could be as simple as a fluid and filter change or could be the indicator of more issues. Good luck and let me know if you need anything else.

Give it a little time. the computer in your car needs to re-learn its idle. very common in jeeps and big time in Fords. Check the trottle plate as well as that could be dirty and your computer can't make the adjustments. It was fine before if the plate is dirty because it slowly got that way and was able to gradully make the change in your idle. If you do clean the trottle plate disconnect your battery so it will reset again. It will need to re-learn again after that. I hope this helps you and good luck.

The problem is that you need to understand OBD 2 Systems first

Then diagnose whatever the issues were.

You do not just put parts on any vehicle hoping to resolve an issue.

You only replace any part when it was found to have failed
or reaches a certain milage and is due to be replaced.

In most cases that will require the use of a volt meter or an
oscilloscope, as well as system knowledge.

There could be 20 things that could cause a problem

You have to use the codes you get,if any, to start a process
of elimination.

check for bad tire, or bad allignment!
