Changes, Cautions, Corrections
1969-70 FORD POWER WINDOWS STICKING IN UP POSITION: Problem is caused by the nylon gear "growing" or distorting due to moisture. Problem is solved by replacing gear with later type "Delrin" gear, not affected by moisture.
1970 ALL FoMoCo VEHICLES EQUIPPED WITH POWER WINDOWS: When servicing a 1970 vehicle for power window malfunctions, the door drain seals should be removed to prevent the possibility of water accumulation in the area of power window motor.
1970-71 THUNDERBIRD INOPERATIVE POWER WINDOWS AND AIR CONDITIONING: This malfunction can be caused by an inoperative power window relay which provides power for both systems.
1971 FoMoCo POWER WINDOWS INOPERATIVE-PREVENTING WATER CONTAMINATION OF RELAY: Inoperative power windows may be caused by water entering power window relay. To correct condition, remove relay and apply a 2" x 3" piece of pressure sensitive tape over terminals (see illustration). Rotate relay 180° and reinstall with attaching parts at bottom of relay.
