This listing is for an RARE NOS (New Old Stock) 9-Port A/C Vacuum Mode Switch (Part # 16037778/15-71389, Interchange 7897082/15-7974) for a 1978-88 G-Body (Monte Carlo, El Camino, Malibu Cutlass, Grand Prix, Bonneville) with factory air-conditioning. This mounts on the back of the A/C-Heater Control.
This is a NOS (New Old Stock) unit. That means it was manufactured years ago by GM but never used. It has never been installed and is no longer in reproduction. It has been tested and works perfectly. The box is beat up but the switch is in fine.
