Interior light issue
Just bought my 91 sl and the interior lights don’t come on when I open the drivers door,I tried pushing in the door jam switch but nothing happens
when I open the passenger door both door lights and interior lights come on. Just nothing with the drivers door. Any ideas what to check

Maybe someone will see this thread that knows where the problem lies.

The left dome light switch works as it should when you push the buttons to turn it on/off. The problem that the OP and I are both having is that when you open the left door (without opening the passenger door, none of the lights come one. If you open the passenger door, the correct lights come on and if you walk over and open the driver's door, those lights come on exactly as they should. If you leave the driver's door open while the passenger door is open and then close the passenger door, the driver's side lights immediately turn off.

2. Please tell us where the LF SAM module is located.
3. Since the lights will turn on in driver's door if the passenger door is opened, are there two wires on each door that go to this module?
Thank you for your help.
