How do you repair the automatic trunk closing system on a 1987 Cadillac Brougham Or is it just easier to install a manual type?

YOU HAVE TO EXPLAIN IF ITS THE RELEASE OR PULL DOWN THATS NOT WORKING.

I'LL GUESS THAT IT'S THE PULL DOWN. IF THATS THE CASE AND THE MOTOR IS

GOOD,(RUNS IN BOTH DIRECTIONS WHEN 12VOLTS IS APPLIED) IT'S MORE THAN LIKLY

THE LOWER SWITCH THATS MOUNTED ON THE MOTOR. I WOULD RATHER KEEP THE

ORIGINAL THAN GO TO MANUAL,IT'S NOT A BIG JOB.

GOOD LUCK

I have the same prob, changed the motor and no go. where can I get the wiring diagram for this closing motor

The wiring diagrams for these electronic details aren't included in the Haynes or Chilton manuals, but there are good diagrams and fault search test procedures for nearly all electric accessories of the Cad in Cadillac's own workshop manual. It is a thick book but very very good, and can still be found at eBay.
