Re: recovering R12 - antique recovery machine - useable/worth it?

You could contact Bacharach to see whether they can help with a manual. But with the flooding and the other questions you have about the old recovery unit—and wondering whether it will work at all—would compel me to leave it behind. I wonder, too, whether there's any R-12 in the system to begin with...

Re: Noise from console while changing vent position

If I understand correctly, it appears that the two cams (white plastic parts) and actuators still work, just that the cams touch and make noise—although I don't hear any mechanical noise in the video, only voices. I'm guessing that one or both of the shafts on which they pivot have moved laterally s...

Re: Noise from console while changing vent position

I can't tell from the video, but is one of those cams (lacking a better term) interacting with the other cam, or do they move independently via separate actuators?

Re: Old school AC system compressor burned out

If memory serves (and it has been quite a while), the Compressor Thermal Limiter Switch on a VIR system from the early to mid 1970's opened with a pressure anomaly on either the high or low sides. Once it opened, it couldn't be re-set and had to be replaced, like a fuse. I remember changing those sw...

Re: Vintage air monster condensers

A search resulted in one heat-transfer products manufacturer who produces all-aluminum parallel-flow A/C condensers in 18 mm (0.71 inch) and 25.4 mm (1 inch) fin depths, probably in whatever length, width, and connections that you're looking for.

Re: Old school AC system compressor burned out

It has been quite a while since I worked on or even saw a GM VIR system. If you want to take a chance, you could disassemble the VIR and replace the desiccant bag yourself. Desiccant kits are available in the market. Better yet, I think, is to purchase an entire VIR unit that has been rebuilt by a r...

Re: Old school AC system compressor burned out

I'll take a guess about the thermal limiter: If it was the original part from 1976, it might have "silently" failed at some point, resulting in its inability to open and protect the compressor when something went wrong with it. Also, you mentioned that this VIR system was converted to R-13...

Re: 06 Tundra not taking A/C charge

I forgot to mention this earlier, but your 2006 Tundra (4-door model) takes 21 ounces net weight of R-134a and 7.75 fluid ounces of PAG-46. The 2-door model takes 23 ounces of R-134a; the oil amount and type are the same as the former.
