1972 rear air switch help !!!!

[72MARIO]

I had to take the plug off the wires in order to fish it down the front windshield post. Now that i am getting back to completing the wiring i cant find the diagram i made as to what wire goes where. All i need is a pitcure of the wires that plug onto the rear air switch in the dash. Thanks for any help !!

So when i turn on the switch there are 3 speeds in the order of - high- low then medium does that sound right ??

OK, My switch may just appear to be wire that way.

Here's the service manual wiring schematic. It looks like the blue and yellow are switched

Hello all. I'm new to this forum, as I just purchased a '72 Suburban. It has a - what appears to be - functional rear air conditioner. I think the dash switch has seen better days. Of the 4 position switch, off works , and what-I-believe-to-be medium works. Low and High positions do nothing. Anyone know where I can buy a replacement? LMC Truck is a recent discovery for me - they have a lot of great stuff, but I couldn't find this specific switch.
Thanks!

Just following up on my earlier post. I was able to get a replacement switch from Randy500 in this thread: http://67-72chevytrucks.com/vboard/s...d.php?t=725056 Thanks Randy500!
