Well, after visiting Orlando for a week, in the 90 degree humidity, I got back to D.C. and decided that It would be nice to have some air conditioning in my car. So, I broke out my old set of gauges, added some dye to the system, and charged it up. Found a leak RIGHT at the compressor on the high side! Replaced the O-ring, charged it back up again, tossed on a new belt, and Voila!!! I've got A/C!!!! Man, this summer is gonna be AWESOME!!!!

did you use the R12 or convert to the 134,, I think mine works but not enough freon,,,wont get cold,,,,

AC is great... to REMOVE!! muahahaa

O_O i want AC TOOOOO .. noone have time to make a how-to manual to mount it?

yea mine needs to be recharged, but I think I'm gonna convert it to R134a, anyone do this? whats it involve?

So you were gonna keep charging it up to find leaks? That seems quite expensive to keep wasting freon, why not use a vacuum pump[ and do a leak down test with a sniffer, you have to have a vacuum pump any ways to charge it yourself.

drain it totally, swicth the compressor leads to 134a leads, and recharge with 134a oil and freon, presto your done. Dont buy an adpater kit, just buy 2 fittings for the compressor and your done.

I would advise changing allt he O rings in ALL fittings, the accumulator, and hope the compressor, evaporater etc is still good.

Lt. Dan

I own a vacuum pump, and used it to put a vaccum on the system. I stayed with R12 because I have quite a bit of it lying around still, and it blows cold as hell!!

I converted mine to R-134a and it sucks. I liked the R-12 much better. Damn naziesque price gouging epa! Houston summers require a really good a/c system. I didn't think it was up to par when it worked to factory specs but its much better than nothing. The really sad part is that R-134a isn't any less damaging to the environment than the R-12 is. Its just a little different. I need to go outside and uselessly spray a couple of hairspray bottles to let off some steam now.

Go do some research on Hydrocarbon refrigerants. I have converted two of my vehicles over so far and they cool as good as r-12. One was a r-12 vehicle and the other was a r-134a vehicle.
And before anyone goes off the handle on flammability, go do some research, r-134a is more combustable under pressure in the a/c system than Hydrocarbons are.
Hydrocarbons are a blended refrigerant, so make sure your system does not leak, because if the mixture gets off by unequal loss of gases, the system will stop cooling.

I did research last year on bus fleet AC and they 100% agreed 134 is inferior to R12. The conversion efficiency is lower and it's a complex compound so it can get weird with differential attrition.

R12 is expensive: cost me $170 last year for a recharge but it blows very cold.

Must B Nice..I put r-134 in mine, worked fine that night. Now, compressor won't kick on anymore. It will if I apply 12volts, then blows cold. AC light comes on inside car, but no 12 to the compressor. Anyone got an idea? No special fuse or link for this, is there?

R12 is illegal to buy here anymore. If you have it in your car, good for you. If you have it in your garage, good for you. If you don't, be careful who you buy it from... it's $$$ because it's rare and not allowed. You R134 or nothing now.

funny thing is i use my Air Con more on cold rainy days to stop the car fogging up than i do on a 35deg C summers day here in Oz.

Lt. Dan

In the US it's not illegal to purchase, you just need a license. Oh, and it's EXPENSIVE... the reason is because you can only buy recycled R12 now...

Sounds like the pressure switch at the accumulator isnt seeing enough pressure to close the circuit to the compressor, id say its a little bit low is why...
