2002 WJ 4 liter automatic (Grand Cherokee)
Bill,
In my '02 WJ 4 liter automatic I have no illumination on my transmission or transfer case shifters at night. I took the console apart a week or so ago and where I expected to find a couple burnt out bulbs there were no bulbs. There is, however, a thin plastic sheet with 2 electric terminals that go to a small "black box" that then plugs into a part of the wiring harness at the aft end of the shifter mechanism.. Is that plastic sheet the lighting unit? Is there a proper test procedure? Thanks in advance, -billy |

Is there a proper test procedure? Your describing an EL (Electro Luminescent) panel. Inside the black box shoud be a step-up transformer. Measure at the box for 12V on the input. Light reading http://www.talkingelectronics.com/Pr...itELine02.html Not so light reading. http://www.wjjeeps.com/gauges.htm (although it's for the instrument panel) Since EL is darn near indestructable I'd be checking the fuses first. -- DougW |

Re: 2002 WJ 4 liter automatic (Grand Cherokee)
Doug,
Hopefully the fuse is the problem. Does anyone out there know which fuse controls the illumination? I haven't noticed any other electrics non-functional so I am assuming it is fused by itself. -billy "DougW" <post.replies@invalid.address> wrote in message news:V%wue.20608$mC.13008@okepread07... > Billy Ray did pass the time by typing: >> Bill, >> >> In my '02 WJ 4 liter automatic I have no illumination on my transmission >> or >> transfer case shifters at night.
