#91 of 209 Re: 2005 jeep grand cherokee electrical problems [2006jgc] by NikJeepGC Jan 14, 2009 (6:00 am)
Replying to: 2006jgc (Oct 30, 2008 1:58 pm) I just purchased an 05 JGC 2 weeks ago, and just this morning on my way to work, I experienced the dash panel lights all turn on at once, then while that happened, my speedometer, and gas gauge dropped and rose again after the lights went back off. It happened twice, and I'm pretty sure this thing has some issues, which breaks my heart because I love the car. Replies to this message: tuggajb (Jan 19, 2009 2:01 pm)
#92 of 209 93 Grand Cherokee Laredo - voltage by wolfdadg Jan 19, 2009 (8:56 am)
I just bought a 1993 grand cherokee laredo - the problem is -- the voltage gauge drops from 14-18 at start up down to 9 or lower as the jeep warms up or I turn on heater, lights, wipers and then wants to stall. The alternator is new but had it checked twice to make sure was working right, the starter is new. I even tried changing the PCM with one from another 93 ( wouldn't even start ). I put the original back in and the jeep started up. Not sure what to do now. any help would be greatly appreciated. Thank you -- George Replies to this message: tuggajb (Jan 19, 2009 1:59 pm)

#97 of 209 someone please help! by bovee Feb 15, 2009 (8:50 am)
I have a 04 JGCL, it has been in the shop 3 days now and is racking up labor cost. It seems to shut off whenever I hit any bumps in the road, at high speeds, only the speedometer and fuel gauge seem to be effected, they zero out and then come back. At slow speeds, when I hit a bump, it stalls. Mechanic says it is a short (no kidding!) but he can't locate it. Has anyone else experienced the same problems?

Replying to: bovee (Feb 15, 2009 8:50 am) That doesn't sound like a short. It sounds like a broken circuit or bad switch. Have they checked all the electrical connections?   tidester, host SUVs and Smart Shopper Replies to this message: bovee (Feb 15, 2009 6:51 pm) tidester (Feb 16, 2009 3:52 am)

Replying to: tidester (Feb 15, 2009 12:30 pm) not sure what they have or have not checked, I got frustrated with the mechanic and picked up the truck today, now it won't start at all and the fuel gauge is reading empty, the low fuel chime keeps dinging, and when I drove it home, it had 3/4 tank. What kind of circuit or switch should I be looking for, and could this be a bad fuel pump or sending unit? thanks for your help. Replies to this message: tidester (Feb 16, 2009 3:52 am)

Replying to: bovee (Feb 15, 2009 6:51 pm) The speedometer and gauges are all electronic and there are a number of electrical connections between the battery and these components. The problem could be at any of those junctures. I don't have hands on experience and don't know how accessible any of those would be so we'll have to wait for someone knowledgable to jump in here - anyone?   I am a little surprised the mechanic didn't pick up on any of this (electrical, fuel pump, sending unit, etc.) if starting it is such a problem. Perhaps a new mechanic would be helpful?   tidester, host SUVs and Smart Shopper
