When ONLY opening driver rear door, interior dome light won’t come

My dome light comes on when you open any of the 3 doors except the drivers side rear door, at which the dome light does not come on. The spring loaded button in door jam is not stuck and functions properly from what I can tell. Any suggestions?

 

I wouldn’t say it “functions properly” being that it doesn’t and clearly an issue. Maybe remove the rear door pin switch that DOEsS work properly and install it on the bad side. This WILL eliminate the pin switch itself. If still happens improperly, then there is a break in the wire somewhere.

 

Thanks Do58, I should have said that the door pin pushes in and out under spring pressure (does not stick in one position or another). I will look into your suggestion.
