Description & Operation

1995 Buick Roadmaster Estate WagonSECTION Description & Operation

All models use a power trunk pull-down system that pulls down and latches the trunk lid during the last 1" (25 mm) of travel. A combination latch/release mechanism is located in the trunk lid. A permanent magnet pull-down motor is located in the trunk lid opening lower panel. See Fig 1.

When the trunk lid is closed, very light pressure is required to cause the latch to grab the extended striker on the motor. The motor will then run, taking the lid to its completely closed position. The key lock frame then depresses the plunger switch breaking the circuit to the motor. The motor will then shut off.
