Hi, Have the 1995 Ford Ranger XLT dome light always on issue. Saw a Youtube video that showed cutting a GEM wire fixes the issue. But my GEM module is different from the video. I have a 1995 XLT 3.0. It is not the door switches. Dome light will not turn off. Previous owner simply pulled the fuse. But I would like an operational dome light. Some feel the dome light delay goes bad and, as a result, the light stays on. Searched the Internet but could not find the wiring diagram for my model GEM module. Any help is greatly appreciated.

 

See if this helps: 95RangerWiringCourtesy.pdf

 

And here are these

Also could be interior lamp relay is stuck closed, so included that diagram
Relay Box #1 is usually above gas pedal area, but they did move it around, lol.

 

Thank you so much. Hunted all over the Internet for these. One site had those ask a Ford mechanic offers $28 to ask a question. Thank you and thank the forum.

 

You don't need the GEM, I took out the GEM in my 1995 3.0 2WD and the truck will still drive.
Great little truck just bad electrical system. rewire or ditch the GEM and get a flashlight.

 

Well not quite true, on some base models there was just the GEM timer module not a full GEM module
On the Rangers with full GEM the wiper/washer would not work along with dome lights if GEM was removed

 

You do lose some features without the GEM but mechanically the truck will drive without it,
I'm just trying to point out if you know a little about electronics you can rewire the circuits and MacGyver a work around.
The truck is old rusty and not my daily driver so I keep it running anyway I can. There's hardly any new parts Inventory for these vehicles anymore.
The best thing you can do to prevent further electrical issues is clean all the corrosion off the electrical connectors and tape them up with electrical tape to seal them where you can.
electrical tape is easy to remove if you have to take off the connector later.
I'm thinking I might put vaseline on some of the connectors before I reconnect them next time I have to.
Vaseline shouldn't affect conductivity, only thing it might get a little gunky if you don't seal the connectors..

 

Yes, the GEM is only wired into Cab electrics, nothing to do with drive train and engine computer

Just put the grease/vaseline on the plastic part of the connectors not the metal parts/contacts, you want the metal parts to make good contact, but you want the -plastic parts to seal out water and air to reduce corrosion of the metal parts
Coating on metal parts will reduce connectivity, except where its scraped off when connections are made

Di-electric grease is made to be non-conducting so you for sure don't want it to be on the metal parts/contacts
Vaseline can conduct electricity somewhat, like most greases, but I doubt it would cause a short with the lower voltages and amps in vehicle system, could, just not likely
