Now is the perfect time of year to make sure the air conditioning in your Corvette is ready for the coming summer months. If you have to play with the air conditioning control switch in your 1977-1982 Corvette to make the system operate or if the control lever is sloppy and you sometimes hear a slight hissing sound, it’s probably time to replace the air conditioning control head assembly.

The assembly is held together by a small plastic clip and metal spring washer. After 20+ years of use, these Corvette Parts become very loose, forcing you to hunt for each stop in the switch. Sometimes, the plastic clip will break, causing the switch to separate which means the air conditioning controls won’t even operate.

The good news is that the repair is very simple and the only tools needed are a few Phillips screwdrivers and some white lithium grease. Start by disconnecting the battery. Then, remove the shift lever knob and T-handle, if it is a 4-speed. Remove the console side trim and console top plate screws.
