Your 1992 Cadillac Seville trunk will not close all the way down is it the trunk motor or the pull down actuator?

Answer 1

ANSWER:

There are two fuses that power this system:

A 40 amp Maxi fuse in the under-hood fuse panel.

A 15 amp fuse in the under-dash fuse panel.

Are you sure you checked both?

Is there a "Trunk Ajar" light on the dash?

From there, check that you're getting power to the pull-down motor at two points:

1. The Orange wire

2. The Dark Green wire

The Black/yellow wire is the ground feed that goes to the latch switch. It provides the ground for the pull-down motor, so see if it is providing a ground. If so, the motor itself is suspect and should be checked for binding etc. prior to replacing.

If you don't have the funds to replace the motor pulley, simply consider the following:

Simply tap the silver bar located on the motor's left side downward into it's pulled down ending place. Having done this, your trunk will lock and close and protect things in your trunk as well as theft of your car. Just keep tapping with a gentle hammer hit until the trunk closes. Your electric trunk open will still function (if it is already functioning) and the water/snow will stay outside where it belongs. Replace motor later. It's about $40 US dollars as I recall.

I found that the hammer technique did not work, so I opened the motor to gain access to the rotor and turned the rotor manually to adjust the position of the silver bar. Doing this put the trunk light switch out of commission, so I removed the trunk light and now keep a flashlight there. Put the rotor back in its housing and reattach housing, so that manually adjusted position of the silver bar is retained.

I did everything that they said in this answer, but nothing happened. What i did to make it work was to make sure the switch on both the motor (next to the silver latch) and the trunk lid (i small black switch in the housing).
