My car (2001 Wagon, Canadian) intermittently thinks that the drivers
doors is open, audible warning signal comes on, and dome light,if
activated for door.  I cannot seem to find the switch  - I suspect
there is a short in this switch causing the car to think the door is
coming open - when is the trip switch located?

Also the rear left door latch does not always engage, I have
lubricated, and works manually when the door si open, but seems as
thogh the spring loaded bumper behind the door post on thye lower C
pillar is not providing enough resistance to engage the latch - anyone
else have this problem?

Any advice is welcome.
