Blower motor switch

I've got a 2006 Peterbilt 379 and the blower motor switch failed. It seems the only way to get a new one is buy the entire control module from anywhere from 600-700 dollars.

The only blower motor control switches I can find are the style that are in the older petes. They have a metal back with a pigtail harness coming off of it and 6 wire.

I've attached pictures of what mine looks like. Does anyone know where to buy these switches or even who manufactures the control unit for Peterbilt so I can contact them and see if they have a replacement switch.

I can't stand the thought of paying 600+ For the whole HVAC control module for a 10 dollar switch.

 

I've found the entire HVAC control panel. And the cheapest I've found it is 400 used.

As for searching for the blower switch my biggest problem is I don't know who manufactures it. So besides the term blower motor switch I really don't know what to be looking for

 

There is a number stamped on the front. PA66GF33. I've searched this but it comes up as ford related. Nothing Peterbilt or correct blower switch.

Here's a picture of the inside of the blower switch. It's definitely the switch and not the resistor.
