lemon law states that they have 3 attempts to fix the same problem, so in the documentation make sure the problem is stated as it was the first time. if i remember correctly there are 2 wires running to the lock for the lift gate 1 of the wires is ground and most dfinately the other is the lock command, you should be able to check for a short to ground and then look for the voltage on the other good luck

intermitent flashing lights

last night in the middle of the night, the headlights started to flash on and off as though the alarm was going off. the horn was not sounding though. it was not a consistent flashing. i started the car, after turning it off, it no longer flashed. what might be happening? also two days ago when i turned off the car, the interior air conditioning blower stayed on. it turned itself off after about 10 min. and has not done it since. it was very, very hot that day (110) and i had been running a lot of errands... again, any clues?

It sounds like the accessory switch for your ignition key is faulty.

i have a 98 Grand Cherokee with 224,836 miles 2 weeks ago the AC blower would intermediately stop blowing now it blows but the ac stopped blowing cold. i know thats not what you had wrong but this is what is happening now. driving home my instrument panel went dead. all guages, radio, blower, power windows and locks quit working etc. vehicle stayed under power. then the gauges came back to life and went out again. drove 30 miles and it came back on. What the heck is going on. I have had little to no problems. the other wierd thing is that my rear passenger window hasnt worked in 2 yrs after this episode the window now works.

My jeep started doing the same thing but not only when i would turn but when i stopped at a light. It seemed if i kept it reved up to 1000 on the rpm it didn't die. Now I am having trouble with it starting. I can't trust it I have replaced about everything on the thing except for the PCM which seems to be where it is leading

ok, today my 99 grand cherokee laredo 6cyl 4wd went to the mechanic with this identical problem, and as i thought it was the cps (crank position sensor) which fixed this problem. final cost $193, of which $61 was part, rest was labor and tax. i took to a NAPA auto repair center. Dealer wanted about $300 total. Do it yourselfers beware, this part is very hard to get to, in a extremely tight fit in an almost impossible to reach place behind engine on top of bell housing. And its not as simple as just unbolt old, bolt new, as the sensor has to be adjusted to have a certain gap between it and the marker for it inside housing, as it works by a magnetic field, which may explain why so many do it yourselfers on this site replaced cps and it didn't fix and then kept spending on other parts with no success. i got a 1 year 12k mile parts and labor warranty on this. Save the do it yourself items for simpler tasks, even the mechanics have trouble with this one with all the proper tools.

Parking Brake Indicator Light

This light has remained on for about two weeks now. There appears to be no problem with the emergency brake or my regular breaks? Is it possibly a bad sensor?

I bought my 1996 Grand Cherokee Laredo second hand , It was running fine and now I am having problems with the alarm I disconnected the switches on all the doors and now when I start it the alarm sounds and the headlights flash for several minutes . But the vehicle runs . Is there any way to disable the alarm . I can operate with the flashing headlights but I had to disconnect the horn . Another related problem is the gauges and power windows will not operate while the ignition is in the run position they will however momentaril;y work if zI turn the key close to the start position . It is not in the switch or the column because I replaced both of them attempting to correct the problem

This happened to mine about the same time of year..Dec 2008. You've probably sold it by now? What I did was fit a relay into the circuit to the feed to blower motor, which only (really comes on when ignition is switched on....I even kept original spade connector in place, if someone later wants to fix the proper way, since then...cured..basic, but safe and works...
