Without using the door switch or keyless entry, the power door locks open and close on their own. Also the dome light goes on/off on its own. On the dash, the door ajar light comes on intirmitently along with the warning beep. What might cause this? The only thing I have had done recently is tire spin balance and this problem started after this routine maintainence was completed. It is really wet here now---possible corrosion?

Electrical gremlins, that what it is! Really though, this sounds like an odd electrical problem. I would start by looking at the battery terminals and make sure they're clean and tight. Then check all the control modules in the car for diagnostic info related to this problem. Also, have your local shop check for technical service bulletins from Form regarding this issue.
