Check the main door swicth for loose wire,s,all so look in side the door jam where the harness goe,s in to door,may have a pinched wire.
"Sometimes" problems, especially electrical, are almost impossible to detect. Removing the door panel and "wiggling" the connections is about all one can do. That, like TST stated, is checking for obvious pinched wires.
