Driving home last night in my 87 GL, the interior lights started blinking
off and on. (WHAD-UP!).  The back rear light is not attached to the shell
and I'm wondering if this is the problem. I'm thinking that it may be a
ground fault and that the lights must be grounded to the shell (or
attached) to work properly. I was reading the haynes manual and looking at
schematics and I really couldn't determine if they are supposed to be
grounded to the shell or not.

Has anyone had this type of problem ?
Am I chasing the right rabbit ?

TIA
