NOS 1978-88 G-Body 9-Port A/C Vacuum Mode Switch – Monte Carlo, El Camino, Malibu, Cutlass

Here's a rare find for any G-body restoration project.

This is a New Old Stock (NOS) 9-port A/C vacuum mode switch, perfect for 1978-88 Monte Carlos, El Caminos, Malibus, Cutlasses, and Grand Prixs with factory air.

It mounts on the back of the A/C-Heater control.

The part numbers are 16037778 / 15-71389 (interchanges with 7897082/15-7974).

It's a genuine GM service part, made in the USA, and has been tested and works perfectly.

The box shows its age, but the switch itself is in great condition.

A must-have for keeping your classic's A/C working like it should.
