#170 of 209 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!

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.

#177 of 209 98 Jeep Cherokee Amp gauge intermittent problem by eric_g Aug 27, 2009 (6:35 am)
My 98 Cherokee starts normally, but sometimes, after driving for a few minutes, the 'Check Gauges' light comes on and the amp gauge drops to 9 volts. This continues until the engine is shut off. On restart it will be OK. It does not happen very time but it's happening often enough now to cause me to worry.   Any suggestions as to what the cause/fix might be?   Thanks Replies to this message: dknj (Sep 03, 2009 8:20 am)

Replying to: eric_g (Aug 27, 2009 6:35 am) I have a 2004 Jeep Grand Cherokee with something similar.   Sometimes it will start and run perfectly. Other times, it will not even attempt to start but I will hear the CD changer in the back of the SUV loading all the CD's. I can then wait 5 minutes and it will start perfectly. I notice when it won't start that the instrument dials do go crazy but only when attempting to start it. When it is running, it does seem to run fine.   I have it at a mechanic right now. Initially they told me it was the battery however, I know that is not the entire problem.   Stay tuned, Donna
#179 of 209 Ugly problem? Maybe. 99 grand cherokee smoking hot by srae Sep 04, 2009 (10:57 am)
The guy who jumped the battery reversed polarity, melted a fusible link off the pos. terminal. What else can I expect? Please don't tell me my computer is trash, you hate to see a grown man cry. It turns over, no start. suggestions?
