SUBJECT:
INOPERATIVE POWER WINDOW, REGULATOR TAPE DRIVE BECOMES DISENGAGED FROM THE WINDOW
MODELS AFFECTED: 1985-1986 DE VILLE AND FLEETWOOD
Figure 1 - New Window Regulators
Some 1985-1986 De Ville and Fleetwood models may experience an inoperative power door window due to disengagement from the window regulator
assembly (the window falls into the door). This condition can result if the regulator guide block travels too far and allows the regulator tape drive to
become disengaged from the window. All doors can be effected.
New design window regulators, which include a stop to prevent excessive guide block travel (refer to Figure 1), are available to repair this condition.
Replace the effected window regulator assembly using the following part number information. Refer to Section 5C of the appropriate General Motors
Body Service Manual for removal and installation procedures.
