Update - each time I lock the doors I get a single horn. I cleared the alarm codes (I recall I got a 46) and they haven't come back yet. Here is what I've done...
- Tested the front trunk micro switch in the latch is working - it is
- Tested the rear trunk latch micro switch - working
- I had an extra center console micro switch, so plugged that in and taped it closed - no change
What else should I check? Does the solenoid that locks the gas cap flap have a micro switch? Like I said earlier, I replaced both door latches with new genuine Porsche latches and the door/windows work perfectly. I appreciate any guidance. This is a '98 986.
