what it says. It locks and unlocks, but instead of going "clunk" each time like it used to it goes "brrrrrrp", as if the solenoid is firing about 12 times in rapidfire rather than just the once. Any ideas?
The driver's door will only lock mechanically with the key, but I reckon that's 'cos it's stiff and defeats the electrical locking, making it bounce open again. Irritatingly, such failed locking arms the alarm, so when you absentminded open the door it hoots at you.
