1999 Jeep Grand Cherokee - Page 9 - Answered Questions & Fixed issues

just below the exhaust manifold on the drivers side of the jeep.... u will need to go underneath the jeep an may even have to remove the water shield that is under the front of the jeep..

I am not sure of your question, there is not enough information. However, I had a problem with a diesel Grand Cherokee that appeared to have a fuel shut off problem, it turned out that the header pump was worn out, and it further turned out that the Cherokee had a history of the header pump wearing out. The header is the pump that supplies the injector pump with diesel fuel from the tank, and if this pump goes, not enough fuel is supplied to the injector pump causing the engine to cut out, and having to be bled again. As soon as the engine cools down, the pump appears to be working fine again. Another possibility is that you might have a problem of sorts with your engine. The engine control computer senses the problem and turns the engine to limp mode, which allows the engine to work at a much reduced power output, giving the impression of diminished fuel supply. This allows the driver to get the car to a service agent before further damage is done. Give us some more info to give you a better answer.

It's an electrical fault in the transmission's gear switching. A transmission shop will have to diagnose it, following a guideline called a troubleshooting flow chart. It may be a simple fix, even an electrical connection, but they would know where to start and how to get to it. Get an estimate of the repairs and decide what is best.

you lost all spare keys, you do know the purpose of this system is to prevent what you ask, right> (page 1 in VTSS , FSM, and operators guide stated) have you used the scan tool and see the other errors yet? you have SKIM too>? (immobilizer) the wire cut hack ended in 1995, the only hacking i see that works is here. bulldog. http://www.fixkick.com/Jeeps/VTSS-old.html some hacks work as long as battery never dies. then must be , rehacked. keep 2 working keys at all times, (see operators guide for rule)

did you look at the parts page? (at the least the plug, huh) jeep.com list both as different. buying whole transmission. call the wrecker and ask for hollander lookup on compat? here is one seller on ebay that show campat buy the harness and see capat, http://www.ebay.com/itm/Transmission-External-Wire-Harness-Repair-Kit-Splice-In-42RE-44RE-46RE-47RE-48RE-/331364693032?pt=Motors_Car_Truck_Parts_Accessories&hash=item4d26dff428&vxp=mtr "A500 , 42RE1993 Up" A500 , 44RE1996 Up A518 , 46RE1996 Up A618 , 47RE1996 Up 48RE

MAP sensor code. Check mass air pressure sensor and wiring.

First you need to find the sending unit. Some are by the oil filter. Most sending units sink current so by taking the lead off and grounding it you should get a reading on the gauge. This will narrow it down to whether it is the sending unit on the engine or the gauge on the dash. Depending on the car there are a bunch more questions to be asked but this is a general answer.

service time, huh? the magic is , busted.

WATER PUMP

Could be a fuel pump going bad or partially clogged fuel filter. It could also be a dirty air filter or some of the few electrical components you can replace in the distributor. You might also have a bad spark plug wire that needs to be replaced. The most expensive fix is the fuel pump/filter as it is located in the gas tank and it has to be dropped to fix it. I would try the cheapest options first. You may also have a bad spark plug and I would try putting in a bottle of fuel injector cleaner as well. Sometimes they get a little gummed up.

It comes apart under the dash. The door wiring runs from under the dash through a rubber boot to each door then the electrical connections are made at each of the door sensors. The rubber boot between the door and body is to keep the wirining harness dry, free of corrosion, and getting pinched between the door and the frame.

Look at your orders manual. It is either inside down under the dash to the right of where you plug in the OBD. or it will be uner the hood on the passenger side. The owner's manual has them listed by number and location. Make sure you have a flashlight and a blade fuse puller when you go to do it. It's real dark under the dash.

Go to Part's Geek, Rock Auto parts, or Auto Parts warehouse online and when you get to the parts selection look under front axle assembly and you should be able to find the stock size you are looking for or you can call the dealer parts office and they'll give you the info and price for a new one. Have done this many times. Works like a charm.

Hi, as a general point on sunroofs I have known the white grease used on them to go hard after time and cause them to go tight. Flushing the Runners with a good penetrating oil whilst working the sunroof back and forward can help to free them off, sometimes giving the roof a hand will help to get them moving. jon

P0443 Nissan - EVAP Canister Purge Volume Control Solenoid Valve GO TO YOUTUBE AND SEE IF THEY HAVE SOMEONE WITH THE SAME PROBLEM.

get plug wire tester at parts store and test plug and coil wires if there bad change them to also did you check plug gap?

IF YOUR BULBS ARE GOOD CK THE CIRCUIT BOARD ON REAR LIGHTS. THEY ARE VERY BAD ABOUT GETTING WATER IN THEM AND RUSTING OUT. THEY ARE AVAIALABLE FROM YOUR LOCAL PARTS HOUSE OR ON LINE (DORMAN)

There are two systems to evaluate.

1. Air Blows Fine but not Hot -> Check Thermostat and coolant level.
2. No Air Blows -> Check Blower Motor, Blower Motor Resistor Pack and Blower Control in Dash

this is easy. (are you moving or parked) ill assume stopped. first is the blower working, (seems so) ill guess that no heat in all vent modes, and re-circ, on. next is the engine fully hot, hot means at 180F or more holding (we measure it with a pyro gun) next, are both heater core hoses hot/ at the fire wall? and equal at 180f? yes, good. then the damper is stuck closed i the heater box. no , then there is heater core blockage. (skipping every 2 year flushes are you, sure...) it only takes 2 things hot water ,p[assing through the heater core and air passing through its fins to get hot cab air. just 2.

No one can guess for you You have to check for OBD Codes & use factory trouble charts, to diagnose that module & find a problem
