Steps
Disconnect the battery and remove door trim
Disconnect the negative battery terminal. Release the door-panel screws and clips, unplug the switches and speaker, and peel back the water shield without tearing it.
Remove and support the glass
Reconnect the switch temporarily and lower the glass to access its sash fasteners. Remove the fasteners, raise the glass by hand, and lift it from the door while supporting it upright.
Remove the old sash connectors
Warm the old adhesive carefully with a heat gun and lift the connectors with a putty knife. Scrape away residue without scratching the glass, then clean the bonding area with an approved solvent.
Bond the new connectors
Mark the original connector positions and apply automotive urethane as directed by its manufacturer. Press the new connectors into place and support the glass through the specified cure period.
Reinstall and test the window
Guide the glass into the door front edge first and lower it onto the regulator. Install the sash fasteners, test the window movement, and leave it raised for the adhesive's required cure time.
Reassemble the door
Restore the water shield and reconnect all door wiring. Reinstall the trim panel and clips, reconnect the battery, and verify the window and door controls.
