jps Posted March 23, 2020 Share Posted March 23, 2020 The service manual has a wiring diagram that shows a door pillar switch wired in parallel with the dome switch. I have a dome switch but I don't have a door pillar switch - at least, I can't find anything that would fit that description. Is it located on only one door, or is it only installed on Master series cars? I have a standard sedan. Thanks. Link to comment Share on other sites More sharing options...
Dave_B Posted March 23, 2020 Share Posted March 23, 2020 John, The dome light switch is on the door pillar, on the passenger side, if memory serves me well. Just to be clear it is not jamb switch. It is a little sliding on/off switch on inside of door pillar. Standard series closed cars as well as masters. I believe it is wired in series.

jps Posted March 24, 2020 Author Share Posted March 24, 2020 Hi Dave, Thanks for the response. I have the dome light switch, but here is a photo of the wiring diagram in my service manual. It shows a "pillar lamp door switch" wired in parallel with the dome lamp switch. I don't see anything in my car that could be a "pillar lamp door switch", so I am wondering if this is only a feature on certain models (like maybe the Master limousine?)

Dave_B Posted March 24, 2020 Share Posted March 24, 2020 John, I see what you mean about parallel, hmmmmm. And it says Pillar Lamp Door Switch, so that could be jamb switch. As you say in the 7 passenger sedan and/or limo. IDK Dave Link to comment Share on other sites More sharing options...
Mark Shaw Posted March 25, 2020 Share Posted March 25, 2020 The bulb base is grounded and only one + wire completes the circuit. It looks like the photo below... Link to comment Share on other sites More sharing options...
Mikefit Posted March 31, 2020 Share Posted March 31, 2020 Could it be the ones swingers on the lamp the other on the door pillar????? Link to comment Share on other sites More sharing options...
Buick35 Posted April 2, 2020 Share Posted April 2, 2020 My 35 has the switch mounted on the passenger side door pillar. It works but the dome light only lights with the door closed,weird.It must be a ground issue. 1 Link to comment Share on other sites More sharing options...
