Early GM Dash Bezel Restoration

Lubricate
Here are the heater, defroster and temperature controls removed from the bezel. As mentioned, the connections at the controls are plastic and are normally brittle with age. Use an aerosol lithium grease lubricant on the contacting parts and work the controls back and forth until the grease is working properly. This is normally a difficult area to get at with the controls back in the car, so don't be afraid to lubricate. You might also squirt a liquid lubricant down inside the cable covers to facilitate the wire movement within. Better to be safe than sorry, replacement cables are expensive and not easy to find. Once everything is reassembled, install the restored bezel in the reverse order that you removed the original. Now you'll be happy you labeled all the connections.
