Help needed IDing an A/C component - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Prong · 08-10-2009, 04:13 AM

Do any of you guys know the exact name of this part? I suspect it cuts off the outside air when the a/c is selected. It sits in the passenger side cowl area under the cowl screen. I need to replace it due to the fact that the "hinge" area that allows it to open/close as required has almost completely broken. It came off of my 79 K10 with the factory air. I found one number stamped on it which may be a GM number: 6262685 -A Any help on locating a replacement would be much appreciated as well.

You'll have to grab one from a truck. I've never seen a replacement available.

Here is a photo of its location:

It's stock, I've got one in my '78.

MY '78 GM Manual says it's called a "AIR INLET VALVE". The one in the kick panel is called a "PLENUM VALVE". The valve you have pictured blocks or allows incoming air to pass into the Plenum and then into the cab.

Thanks for the info. Does it list a part number, by chance?

no part numbers, I only have the fixit manual and not the parts book. It'll likely be a junkyard item.
