recently when the car, 1991 Honda Accord EX Wagon is driven over a bump, the door locks pop up. i push them down and at the next bump, they pop up. any ideas of what to look for? the car is usually driver 20 - 30 miles a week.

 

May be an issue with the power door lock control unit. It is located under the driver's seat. Check that the two electrical connectors to the unit are okay, and the unit is firmly bolted down, to rule those out. Otherwise, you can try to open up the control unit to visually check the solder joints, etc.
