Tired window motor?

Lower the window by 11". Remove the door card and sticky foam, cut thru the flexible glue. Loosen the two window clamp bolts and remove the glass, always use a suction cup to hold the glass. Remove the speaker box then disconnect the connectors from the door lock and window motor - access the window connector via the port in the door. Unbolt and remove the window slider frame. I have removed the window motor and gearbox but it is not strictly needed, using T25 remove the DC motor and worm drive. Clean the shaft and apply a mid to heavy grease. The light oil used by Jaguar dries and there is metal contact, greatly slowing the DC motor. With that done replace, paying attention to the brush contacts. Re assembly is a reverse of the procedure. With the glass now in keep the window bolts loose and close the window fully, now tighten the glass clamps. Result: one rejuvenated window motor.
