Hey my rear cargo light on my 90 doesnt come on when I open the hatch...but it comes on when I open any of the 4 doors. What is up with that??? Any insight to that problem? Thanks.

 

Best bet-- Broken wires between the hatch and the body. Years of opening and closing the hatch have probably flexed the wires enough to break the wires inside the loom!! Easy fix, cut the loom open and repair the damage..

 

ok but where and what is the loom????

 

The rear hatch door switch is probably bad

 

Or the off switch on the dome light itself is bad/broken. When you open the hatch you can flip that switch to turn the lights off. I replaced that switch with a mini toggle that looks factory from ebay, <$2 shipped and solved it for me.

 

mine is same. its cause the whole lift gate was replaced... i think wires are not easy to get to...

 

Does your rearmost domelight have TWO black buttons?

Open hatch and click one until the lights come on.
Then close the hatch...they should go out. (If not re-click the one you chose and click the other...re-try test)

The "wire loom" is the cluster of wires that connect the hatch wiring to the rear harness.
The loom can be seen on the upper left corner of the hatch opening.
The connectors for this loom is located BEHIND the tire-side interior panel. NOTE: These are a P.I.T.A. to get to.

The actual triggering switch is mounted onto the backside of the latch mechanism itself. This can be accessed by removal of the hatch interior panel

 

i know on my 90, there is button and you have to press it when open to control if it turns on or stays off when open. you just have to open it, and press it.
