Generally
The bottom part of the double electric lift connector that controls the front ventilation windows on the left and right side, if you have a Fleetwood 60 special, the connector also fits the rear ventilation windows. It is this connector that gets worn and burned inside. It is a used, cleaned and tested Cadillac original connector with part number 4727292 that works perfectly. Replace it and the vent knob will be like new again.
