1971 RR AC Blower Control Switch

[ct71rr]

Hello all, I started cleaning up my heater/AC control unit for my 1971 Road Runner. And, like everything else on this car, a PO decided to “fix” it previously. It looks like my AC blower switch has been modified or it’s the wrong one. When I took it out for cleaning, it was held in with a DIY brace covered in electrical tape. It also looks like the original mounting “wings” have been cutoff and the remaining pieces bent in. The wire connections are pointed straight up, on others online, they appear to point to the right. Is this even the correct switch?

What I have:

What I’ve been able to find on the internet:

Any help is greatly appreciated!

Chad, the one you found on the internet looks to be somewhat correct, but the number of connectors looks off.
The mounting pattern is the same.

Here's a pic of the back of my blower motor switch.

I assume the non A/C and A/c one would be the same.

Thanks John! I’m thinking someone cut up the mounting plate for some reason. It was done pretty accurately though, looks almost factory. I can’t figure out why they would though. I found switches for A, B and E bodies on the internet and they pretty much look the same as yours and the images I posted.

And my plastic mount is white where others I’ve seen are black like yours. I’m guessing that’s one of the differences between AC and non-AC?

Chad, the white units I think are 1972 & up units. On the photo above the two open holes on either side of the fan switch are for the dash lights.
The white plastic unit only has one hole for the dash light, that's another indicator that its a 72 & up unit.

Or, I'm completely off as I've not seen an A/C unit in person to tell the differences.

From what I’ve been able to learn on the internet from my deep rabbit hole dive , the white assembly is “correct” for ‘71-‘73, or will work with those years. I found a match of mine - same part number- on ebay and it is white and has the two holes for the two bulbs like yours. I was also able to find an nos switch that is the same as the one i have, mounting tabs bent forward with tapped screw holes on each side. It also has “F” marked on each of the three wire mounting tabs like mine. Apparently this is correct for ‘73-‘76 A & B bodies.

eBay Unit:

Same part # as mine:

My control unit, same part #:

Switch:

Same “F” on wire plugs and bent forward mounting tabs with tapped holes:

My switch:

Thanks for your responses john!
I’m either going to modify the mount to work on try to find the correct switch, which I haven’t been able to do yet. I’ll also have to try to figure out a way to test the switch I have - I have zero experience with electrical and switches.

Hmmm, I just learned something new - thanks Chad!
