Was wondering if the cab and cargo lights are on the same circuit? I can't get my cargo light to work when I open the doors, only when I lift the hatch. If not, is there a way to wire the two together?

 

I had the same problem with my ZJ. It just switched off at the cargo light, I pushed on the light and it came on. Maybe yours is the same, or the bulb is bad.

 

This would be the first thing to check. Just push the light lens. I had the same problem when I bought my first XJ until I found out that the lens has has the switch in it.

 

Cool. Fixed. Bulb contacts were a bit narrow so I stretched them out a bit. Works when doors open now. Thank you :-)

 

Cargo dome light switch did nothing. Turns out it is in SERIES with the liftgate latch switch, which is grounds the interior lighting circuit. Liftgate switch was not functioning at all and leaving the light circuit open.

Fixed the bent part. All works fine now. Thanks for the help.

I would suggest anyone having issues with lights staying on, or not coming on with lift gate or cargo light switch operation check this item out. The interior panel on the liftgate needs to be removed. (Be prepared to use screws to reinstall, since removal seems to destroy the plastic nail holders.)
