My door ajar light stays on when it rains, or is hot outside…Any ideas?

Henry

You may need to replace the switch for the door in question.

Where is the door switch located?

The door switch may integrated into the door latch. A body shop might be a good place to stop and see if they can help

That’s great advice, but I’m looking to do it myself…Thanks…Henry

Most of the time squirting some electrical contact cleaner, or WD40 up in the latch assembly fixes the problem

Thanks I’ll try that. I’m an electronic tech, and I don’t understand why it only does it when it rains, or is hot out…Henry
