Usually when there is no blower motor activity taking place when turning on the Autotemp II system, it is due to a failed vacuum check valve in one of the various vacuum lines in the system. Those valves are usually in the lines hanging down on the floor hump or otherwise in the vacuum lines...

All 1971 - 1973 C Bodies have the Autotemp II system, and the one cited above by @Imperial Pete or the one cited by me named Chris. Either one should work fine.

...apart one of the factory heater control valves an sent the unit to a friend of mine here in California that also makes/fabricates the Autotemp II control units to see if he could also fabricate a replacement out of aluminum for the standard heater valve and he told me it would not be feasible...

I have written volumes about this system in the past. Go to the search function and for subject type in Autotemp II systems and for person posting, type in my site name and a lot of threads will take you through how to fix the system and where to get the parts or just go to this...

No, Autotemp 1 only on 1967 through 1970 models, Autotemp II only on 1971-1973 models, and Autotemp II + on formals only 74 and up...................................

...valves are not robust and do go bad over time, so use of the OBD II Chrysler tester is also worth having when trying to diagnose the Autotemp II system. Adam's car is a very low mileage (12K miles) 1972 Imperial Le Baron that he covers in detail in another of his videos, one previously owned...

...they are usually not fixable because parts for them (especially the controller in the right kick panel area are no longer available). Autotemp II systems are readily fixable because parts are available for them since Mercedes Benz bought the patent rights for the system and improved the...

In 1971 Mercedes bought the patent rights to the Chrysler Autotemp II system. As such, since Mercedes wants to keep parts available for most all of their historic vehicles, I am assuming they worked with Performance Analysis Company to continue to make them available. Fortunately for us, PAC...

I had a very long discussion with the supplier of these Autotemp II controllers shown above. I was very impressed with his knowledge of these systems and determination in striving for the absolute best quality products possible. You can't go wrong with this guy and also Performance Analysis...

...temp sensing switch closer to the evaporator and premature compressor failures. There are only 2 suppliers of the really good Autotemp II newly remanufactured controllers and either one of them is fine. I also believe you would be doing yourself a favor and work with an A/C shop that is...

...with Performance Analysis on whether they can supply you with some or can recommend a vendor for them. If you can find someone with an Autotemp II tester, try using that as well. Those vacuum check valves are located conveniently at the front of the floor tunnel just under the blower...

...tends to clean leather the best in my experience but seats might also need to be redyed again to get them back to white. Your Autotemp II issues are halfway solved it seems to me since you already have the Performance Analysis Company's (PAC) aluminum controller under the hood, and they are...

He knows it is Autotemp II obviously!! At least that version is fixable.................

...the control unit in the right side kick panel. The problem is whether the effort could ever be profitable. The only reason we have Autotemp II solutions is that Mercedes bought the patent rights to a good system and then improved on them. It is the large volume of Mercedes models worldwide...

...| Performance Analysis Co. They are also very willing and helpful in getting your system to work properly if you run into any issues. Autotemp II is the only Autotemp system that can actually be brought back into good working performance and was available in the 1971-3 C body models. The...

I must have missed your original post in the 1973 Chrysler thread....! New owner probably decided he couldn't deal with Autotemp II - it still has the original controller. Not a big problem though. Just another $800+ or so....

Just curious, you indicate the a/c will be charged before the car is sold. I was wondering whether the Autotemp II controller is original or the replacement one from Performance Analysis Company? Does the system currently work and control/modulate at least the heater temperature currently...

Mercedes Benz bought the patent rights from Chrysler for the Autotemp II system but substantially improved the quality so they wouldn't fail every two years under normal use, just like Chysler's non-Autotemp II heater control valves made of bakelite plastic. Chrysler lost a lot of customers...

I spent considerable time looking through all my 1969 through 1973 parts books (I have them for all the years) while waiting to go to my Christmas dinner engagement and came to some preliminary conclusions. It appears my assumptions that all fuselage vehicles would likely have the same heater...

The Autotemp II systems are not difficult to get working primarily because of Performance Analysis Company's efforts to supply remanufactured ones including the availability of the new amplifiers. The only other things that need to be done correctly are all the hoses routed to their correct...
