If your early door lock actuators do not have any cracks in the rubber diaphragms, but they just won't hold vacuum - it may be possible to fix them by taking them apart and cleaning and resealing the outer lip of each diaphragm. This is not guaranteed, as there may be other problems with the actuator, but we have found that approximately 80 percent of those crack free actuators can be restored using Kent's kit and method of restoration. This video will cover the step-by-step process (when using his kit) of how to take them apart, clean them, reseal the rubber lips and retest when completed. This video is included free with the purchase of the kit (see related products below). This video DOES NOT COVER removing the door panel and removing the actuator from the door. (For additonal help please see related products).

If you discover that the diaphragm(s) is cracked or torn then you will need to replace those affected rubber parts. We do offer a kit with new diaphrams that also comes with installation instructions. A hand vacuum pump tester is required to test any repaired or restored actuator before reinstalling it in the door.
