The Parking Brake May Not Automatically Release on Cadillac DeVille DTS

Problem Description and Possible Solution

The parking brake may not release automatically due to a failed vacuum switch or actuator. Our technicians tell us that if vacuum is supplied to the actuator when the transmission is in gear, the vacuum switch is functioning and replacing the actuator should correct this concern.
