When I lock my car the doorpins flash for approx 30-40 secs before they stop flashing...for good. this in turn seems to deactivate the interior sensors. I wondered if there may be a prob with the switch by the drivers seat, but i thought I'd ask before I start pulling things apart. I tried disconecting/ reconecting the battery, which fixed the prob for about 2 days then the prob returned. Any ideas of whats wrong?
