Strange behavior of door locks
 

Hello:
1997 Boxster, all stock, 32K miles.

All doors closed, top up & locked, hood and trunk closed tight. Hit the key lock on the key FOB. All locks go to lock position, park lights flash, 2-3 second later, door locks pop open.

Tried same configuration with manual key-turn to lock, all locks go to locked position, 2-3 seconds later door lock pop open.

I checked the microswitches in windshield frame for convertible top - behaves normally. Door windows appear to work normally.

I changed driver’s side window regulator about a year ago, reset limits and everything worked fine.

What could possibly be the problem??

Guidance to start troubleshooting this is appreciated.

Best regards,

J

Ignition switch??
