#165 of 207 1996 GCL theft Alarm by georgeg4 Jul 16, 2009 (4:10 pm)
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

Replying to: autobodywizard (Dec 26, 2008 3:02 pm) 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...
#167 of 207 Truck wouldn't start all electrical seems to be working fine! by court1980 Jul 26, 2009 (10:05 am)
I have a 2005 Jeep Grand Cherokee 3.7L truck has been running fine except the radio suddenly stopped working three weeks ago. I went to the store last night turned off my truck and when I returned 5 mins later it wouldn't start! All lights on the dash work, headlights are fine, windows work, sunroof etc. the truck just would'nt start it was silent. No clicking or problems trying to turn over, just silence almost like the key was only turned halfway. This happen once before a few weeks ago and 10 mins later it started fine. Last night I ended up having to leave my truck there after trying to start it for an hour. This morning started up fine! Any suggestions??? Could this be electrical?

#169 of 207 Re: '97 Jeep Grand Cherokee-Battery draw [trekker3] by carolyn996 Aug 19, 2009 (6:51 pm)
Replying to: trekker3 (Mar 27, 2009 11:01 am) Hi, I owned a 1994 Jeep Grand Cherokee for 11 yrs and am still sorry I sold it. Even worse that I replaced it with a 2005 which has big time electrical problems on the gauges,heat,blower and signals. Anyway back to your problem. My Jeep would start fine all week when I drove to work but come Monday morning if it sat all weekend the battery was dead and it would not start. Same thing happened while on vacation on Northern Mich after it sat all week. When I took it to the dealer it turned out that I had too many maps in the glove box which was causing a slow draw on the battery as the glove box light stayed on ( and I could obviously not see this with the glove box closed). I took all the maps out of the glove box and never had the problem again. Good Luck Carolyn996
#170 of 207 Problem with UConnect in my 2005 Jeep Grand Cherokee by nolefan9399 Aug 21, 2009 (11:24 am)
OK first the dumb part of this topic. A few weeks ago I took my Grand Cherokee with a sunroof through the car wash. I noticed water coming through by the headliner and quickly found out you don't take vehicles with sunroofs through the car wash. Almost immediately after that my UConnect which is the mirror mounted type quit working. My question is is there a fuse or relay that could have possibly tripped in the system causing it not to work? I have looked around and can't find any wiring diagrams for this system. Help please!
#171 of 207 Re: A VERY ANNOYING ELECTRICAL PROBLEM [mrduck53] by 96jeep2 Aug 24, 2009 (2:41 pm)
Replying to: mrduck53 (May 26, 2008 7:50 pm) i have a 1996 jeep grand cherokee 200,000+, i bought a obd2 scanner for my car it give me a few error code one of the code is p0350 witch is no cam shaft poss sensor signal at the pcm. if this happens the pcm dose 2 things. 1st it shuts down the relay for your ignition/fuel pump 2nd it shuts down the relay for your ASD (atuo-shut-down replay) both shuts off your car while driveing or doing anything. this could be fix 1-2 different things pcm, needs to be reprogramed (not istalling a new one) must be reprogramed, cam sensor needs to be replaced. The best advised i could give any one that has a jeep and wants to keeps it, is..... go get your self a hanye's book on your car and do it your self, it's lest expencive, and your learn how to SOLVE issues. Did you know that a kit to repair a transmition is only 200.00$$$. and when you bring your car to get serviced they charge you oohh any were from 1200-2200 depends on the probolem. Ill help anybody that needs it just ask, i am not a mecahnic just a well informed jeep owner.

Replying to: parist21 (Jun 29, 2009 8:07 pm) If your not leaving any thing on in the car, thus causeing your battery to be drained, then its not getting a good recharge, i would take a look at the alternator.
