I'm trying to identify the make of the Heat/AC control panel on my 1985 Regal. It has 6 push buttons, a vertical slide for the fan and a horizontal slide for the warm cool function. I know my chassis is GM but most of the junk yards have said they think this control panel is Chrysler. Does anyone know how I can locate and replace the vacuum module or manifold that sits behind the controls or the entire assembly?

Welcome to the site! You'll find all kinds of good stuff here if you search our archives. BTW, thanks for using a good thread title. It refers directly to the subject and will be easy for others to find in future searches. Try here:

They were made by Chrysler. There are several sources listed. Good luck.

I will follow up on these leads and report back. Thanks!
