Sorry, I Forgot I had this ad up. I found everything I needed. Thanks for the pics and that is most of what I was looking for.

First thing I had to do in this project was replace my blower motor.....that thing was locked up. So apparently, my original control switch did not power the blower in the "OFF" mode or I would have the current drain. The fuse was not blown nor was the motor showing signs of having been...

Do you hear any vacuum noise from the switch when you change modes? I can hear it on mine.

Have you had any experience or seen any reviews on htis reproduction? I can't find any meaningful reviews on it. I assume that with the part number they use on it, that it will run the compressor in defrost mode...which is ok with me. Still waiting to hear back from OER about how it...

So it looks like my NOS switch is bad....so the blower is supposed to run all the time. I guess that's okay, but the compressor should not be running in "HEAT" and "OFF" modes as my NOS switch is doing. I guess I just need another switch. Still waiting to hear from OER about the repro switch...

I read somewhere that the vacuum "T" on the intake manifold...where the brake booster and the small vacuum hose that feeds the vacuum reservoir...can get restricted with debris. I used a short piece of wire to ream out the T where the small hose connects....don't know if it helped or not, but...

The only good thing about the NOS switch is that the vacuum actuators now have full travel....before they were only moving maybe a quarter of an inch or so.

Sounds like we have the very same issue with the NOS switches. I emailed OER that makes the repro switch and asked them in what modes the blower and compressor are energized. I haven't heard back yet, but will post here when I do.

My original was 3431020 and the NOS one I bought was the very same number. Is your compressor and blower energized all the time with your new switch? I can understand it being on for the DEF mode, but not in "OFF". My original switch shut off the compressor and blower in the "OFF" mode.

What part number was on your NOS switch?

Wouldn't that be if the system was the Automatic Temp Control AC option? Mine is the basic manual temp control version. Maybe this NOS switch is just defective.

Was your compressor energized even in the "OFF" switch mode? Mine is with this NOS switch assembly...same part number stamped on it as yours.

I bought an NOS vacuum switch on eBay, part #3431020...for my '70 Suburban non-ATC wagon. The vacuum part now works great, but the AC compressor and blower motor stay on all the time regardless of what mode button is depressed. I've heard that Chrysler did that on purpose in some later years...

I wasn't thinking about going with the pre-70 4 piston setup....that stuff is crazy rare and expensive. Besides my '69 Fury that has those, I also have a '68 Roadrunner with them. The 70 style calipers is what I want to go with on the wagon.

Okay, looks like my initial feeling about going with the stock setup is the correct one. My '69 Fury III has the original factory 4 piston calipers and the brakes feel like I want this wagon to feel....awesome. Now, to figure out what year cars to look for in the junkyard for the "right...
