I am having electrical issues with my 2009 F-150.

Initial problem (30 days ago)
When the driver door ajar alarm comes on, none of the windows are working and also locks will not operate from driver side.

Second issue (5 days ago)
Starting last week, my door ajar alarm came on and has not gone off since.

I was able to get the door ajar light off briefly after I closed the door repeatedly. That was the last time door ajar switch worked.

Today I sprayed lubricant into the door latch mechanism and worked the latch, no effect.

Anyone know the answer?

Were you able to find a solution? My truck started doing the same thing.

 

check the wires in the door jam the harness that runs from cab to door, may have a broken wire

 

Thank you, there was a broken wire in the harness.
