It worked for years with the variable vanes powered by 12V. To be perfectly honest since I know that the system does work on an old convertable that has zero insulation I would rather replace it with a bolt for bolt non variable compressor. The engine is a very tight fit and down where the ...

Somewhere in my absolutely impeccable garage I have a new front plate from the compressor in a 2015 GMC sierra 1500. If you think it will fit it is yours. I never throw away good parts I just put them in hidden corners never to be seen again.

The truck was a 15 gmc sierra 1500 that was the worst wreck I have ever seen. It went off road hit somethhing unmoveable and did an endo. It must have hit hard because both front seat belts were locked in the extended position. Enough of that. The point being that the whole truck was a total wreck ...

I put an LT engine in my 63 Pontiac and as the original car did not have a/c I built a unit out of junk parts and adapted all the factory parts off of the donor truck. Compressor, condensor, evaporator and hoses. Logic was if the unit worked good in the truck it should work good in the car. It is a ...

I have been talking to a lot of people on the "net" and probably the best response was to go to a brushless motor. Apparently they have the most power available for fan motors, a lot more power than a brush motor. Now my problem is to find a controller for a brushless motor. Will be doing a lot more ...

I am driving a 63 Pontiac Catalina convertible. Had it for about 10 years and the first modification was a new engine and trans. LT and 6 speed trans out of a 15 silverado. Had to adapt an A/C and found a unit out of a 96 Crown Vic that could be adapted. I got it in the available space but with all ...

Sorry I apparently was not real clear. I did replace the accumulator but when I disconnected the inlet hose on the evaporator it ran a puddle of bright green oil on the garage floor.
The green oil makes me wonder what was in the system, if it was 134 I don't need to be real careful about cleaning ...

I am ressurrecting an 89 Bronco II for my granddaughter. I am at the A/C now and am going for the R134a changeover. I changed the accumulator and the oil that ran out is bright green. I do not believe that this is mineral refrigeration oil. What are the odds that it already had R134a even though it ...

I am sure this information is in here somewhere but I did not find it. I am trying to resurrect an 89 Bronco for my granddaughter. This car only has 89000 on the clock because the previous owner blew the transmission and parked it in the desert. I have gone through the brake system, fuel system ...

Thought that I would post the findings. In the absence of any useful information on the system operation I wound up taking the whole thing apart to figure out how it worked. My ancestry comes out of southern Germany on both sides so I believe that gives me the right to cuss the Krauts. Essentially I ...
