#147 of 708 Strange array of problems by virgil373

Jun 25, 2009 (7:39 am)

About ten days ago I noticed my 1999 Jeep Grand Cherokee Laredo, 6cyl, 4x4 was leaking radiator fluid. Took it to the shop, they replaced the water pump and also said the cooling fan relay was broken and replaced it. A couple of days later I changed the spark plugs and boots. I then noticed that the interior lights weren't working and tracked down a couple of other electrical issues--button to release liftgate window and the rear wiper weren't working. Took it back to the shop, they traced it to a blowing fuse (#8) and said there was a short somewhere in the liftgate, perhaps the wiper motor or liftgate window button. They are tracking down the short now. I can replace whatever component they identify as busted.
 
Are these things related? Could the busted cooling fan relay have caused a short in one of the liftgate devices? Could I have jostled/pinched a wire in the engine bay (while changing the spark plugs) that caused the short? Do I have a ghost? Thanks for any advice.

MY JEEP HAS 132,000 MILES ON HER SHE JUST STARTED TO ACT UP. THE FUEL GAUGE STATES THERE IS NO GAS IN THE CAR. I ALWAYS FILL MY TANK. THE CAR WILL CRANK BUT THE CAR WILL NOT START AT ALL. I DON'T KNOW WHAT THE PROBLEM COULD BE. MY SECURITY KEY LIGHT JUST CAME ON ALSO. COULD THIS BE A PROBLEM ALSO. I'M TRYING NOT TO GO TO THE DEALER SO THEY CAN TRY TO CHARGE ME A ARM AND A LEG.

When I try enter my vehicle the wireless button does'nt work. I open manually and enter, my dome light does not work. When I try to start it the gages go round and round. It acts like it is totally dead. Then after three or four tries it starts fine. I also noticed if this happens if I slam my drivers door a few times the dome light goes on the it starts right up. I have had it to a mechanic he replaced the ignition switch and the pcm computer. Does anyone have a fix for this?

Ok here's the deal.
I've only owned the vehicle for less than a year. Bought it off a friend when I needed a vehicle. The only issue it had at that time was that the gas gauge would float up and down. Well in the past two weeks some weird stuff has been going on...
The dash light blink on and off
The Blower Motor on the heat/AC won't work
The interior lights are stuck on even when I remove the keys from the ignition. Anyone know what could be the problem here?
Any advice would help.
Thanks

i was wondering if you solved this, my 99 grand cherokee laredo 6cyl 4wd just started this exact same issue today, fuel gage at 0 fuel warning light on and security key light on which is a light i never remember seeing before, i tried my other key with no help, i have 153000 miles, i have owned since 130000, was running like a new car until now, yesterday i had front end aligned and tires rotatated which should not have caused a problem, mechanic test drove after alignment and gave me the car with the engine running, i drove home, shut jeep off, this morning cranks but no start, fuel zero and security key lite on. i called the service manager where i had work done, he asked me if i had moved the tilt sterring, i told him i thought his mechanic had, he said he vaugely remembers that there is a wiring harnes on sterring colum that sometimes pinches when wheel tilt position changed, maybe a wire to ignition switch was pulled loose but i haven't solved, i have changed all fuses related to starting even though they look ok, no help. IF YOU HAVE ANSWER PLEASE HELP!

i just paid to ask an expert on justask.com, a jeep service manager and ASE in automotive electrical, he said the fuel warning light and security key light and no code indicate cps crankshaft position sensor, that it shorts the PCM so it won't display a code, replacing cps should fix problem, i'm having mine towed to a repair shop next week when my AAA membrship for towing takes effect. my choices were tow 30 milles to dealer for parts and labor close to $300, or the local napa repair center for about $130. I have seen many postings here where people replaced this and it did not fix, its also a very hard part to get at, so i'll let the shop fix. The mechanic there agreed with my expert that the fuel warning light and no code being stored make the cps the first place to look, especially on a 1999. He is gonna verify before changing part, keeping my fingers crossed, will post back with results. These internet forums are helpful, but electrical issues with cherokee seems to be a stumper on this forum. Last year my radiator fan got stuck on and drained batterey, then would not come back on after jump, code pointed to fan relay, forums said same, it was fan relay, this case is not as clear cut. I don't understnd why Jeep puts fan relay in suc a hard to reach area, nor do i understand the point of this cps, since what it does is stop spark and fuel if senses crankshaft timing off, and since there is no common adjustment to change timing, what is the point of cps? though i think perhaps it sends a pulse train to pcm to tell it when to send fuel to each injecter and when to fire each plug, takes place of rotor cap, the old ways were easier to fix for sure.

on both sides of the vehicles kick panels there are two large screw in connectors that tie the dashboard to the body harness, i suggest you pull the kick panels out and with the vehicle on wiggle the wire bundles see if you can cause the problems to duplicate. sometimes those connectors don't seat properly or wires get strained. good luck

those switches in the steering column are easy to fix just pull them out and there are 2 wires at each, you can pull the switches apart with out breaking them and there is 3 stamped metal surfaces checked for cracks in the metal pads. good luck

i am sorry to hear that i used to work at the factory those guys are supposed to replace the body harness not repair it for any kind of wiring problem. i do know that the drivers door is checked first by the body computer so it is very important. another problem area is the kick panels on both sides good luck
