The other night I drove ~50 miles with the rear door (right, passenger side) half latched, and the door sensor did not report this. By half latched, I mean that closing the right side door gently, produces a situation where the latch has begun to engage, sufficiently that the door will not fly open, but the left side and right side glass are not evenly aligned.
As I was driving down a 2-lane road, I head this odd whooshing sound when a car passed me going in the other direction. Checking the inside mirror, and the instrument cluster, did not give me any reason to believe the door was ajar. When I stopped for gas, I noticed it.
Looked at the sensor switch on Sunday. It seems that the switch is the kind where any travel at all causes it to register that the door is closed. The switch travel has begun with the half-latch situation, so the computer didn't know the door was not firmly shut. The inside edge of the door has a beveled plastic block that engages the switch. I wonder if the block can be rotated 180° to engage it a little less. Failing that solution, I suppose the head of the switch plunger could be gently filed a few millimeters (to cause it to begin traveling a bit later).
Anyone have any thoughts about this ? Tomorrow I'm going to stop by the dealer and see what they think.
