Wow the way you explained how the air conditioner works without a chalkboard or a board for all kinds of crazy numbers you did an excellent ABC explanation thank you😎
Okay got everything installed and ready to pull vaccum. But you never showed how to wire it. The old air products shows the green wire but my 75 has a brown and yellow wire. One goes to the liquid line valve and it goes to compressor... so do i connect that green wire from that switch to the new plug any green wire then to the accumulator switch? Then run other green wire to the compressor? Thx.
I have a 1972 corvette that I took to a shop to charge the system 2 hr later he said he just couldn't get it to get cold. Driving home the compressor froze causing me to pull over and cut the belt. I would love to have AC again and do realize it's a big job but I don't know what parts I'll need to replace after maybe metal from the compressor entered the system. I didn't return to the guy cause he didn't know what he was doing and he would have denied destroying it. Can you help with info into my problem. I like to fix things myself but need help with direction.
Great video. I did this to my 77 corvette and my compressor will not cycle, it just stays on all the time and I burnt out one compressor already. Any thoughts? Low pressure switch (does it have adjustment)?
Hi, on the kit I installed the low pressure switch is adjustable. I adjusted mine to cycle off when the pressure on the low side reaches 36 Psi. This allowes the compressor to shutoff and the pressure to stableize and come back on when the pressure reaches 48 Psi on the low side. My concern is do you have the proper amount of oil in the system? I would suggest charging with at least 8oz of Pax oil to make sure the compressor is properly lubricated. Please note in the original design of the system the compressor never shutoff and the VIR unit regulated lowside pressure. Please make sure there is oil in the system. I'm here if you have any other questions or need help. Good luck and thanks for watching.
Thanks for making this vid. I am working on an early 77 that still has the VIR. Is this a kit or did you put the parts together yourself? A link to the kit or a parts list or application would be great. Thanks!
Hi V - I purchased the kit from EklersCorvette.com. It comes with all parts needed to do the conversion. It is a little tricky attaching hoses to it due to a swivel fitting so please take your time and also disconnect the hoses from the compressor as this allows for greater mobility of the hose itself.
I can't say for sure about a 1977, but at least 1976 and earlier, there is no water valve...it is a constant flow heater core, with a blend door in between the heater core and evaporator for temp control. on my 1974 which has the old style rotary heater/AC controls in the console, the temp dial has a cable which controls the blend door in the heater core case. I know 1977 has the newer style heater/AC control, so it may not have a cable operated blend door, but if it does, the problem you're having is probably either the control cable is disconnected or the blend door seal is toast.
Hey Steve, thank you very much for the tip, I removed the right side console trim cover and was able to access the cable. I simply slid the temperature adjuster to the cold setting and adjusted the cable by turning the sleeve until the blend door completly closed off the heater core. I'm getting about 50 to 55 degrees out of the vents now. I'm happy. Thanks again!
This was not helpful at all. You just showed us how frustrated you were and then you shaking a can of freon. You don't show me where your new accumulator is, where your new orfice goes, or anything that was at all helpful to someone working on the same kind of car doing the same conversion. Boooo

Your explanation is awesome.

Thanks

Nice wind chimes...

Bryan Russell you don’t represent ‘us’ and it was helpful so take your negativity elsewhere 🙄💩
