Door Windows

Window regulators are individually powered by a 12 volt reversible motor located in each door. The motor contains an internal circuit breaker requiring 1 to 3 minutes to reset. The motor, bolted to the regulator assembly, utilizes a selflocking gear drive. A 2-way control switch is located on each door, with a master control switch located on left door. The window cannot be operated from the door control switches until the ignition is turned on.
