That is correct.

Disconnect the switch connector, and connect the two together with a paper clip. Then run the engine and hit the AC switch (fan will also have to be on - any fan speed). You should then hear the A/C clutch click and see the belt turn the pump.

Don't do this for very long - you don't know how much or how little oil there is in the pump.

What would you have to change if you truck already had an R12 system?

Component-wise there should not be much difference. The condensers are different between R12 and R134a (R134a isn't as efficient as R12), but they will still likely work.

I'm told that things need to be replaced before putting the R134a in...you can't just evac one and put the other in.

The oils are not compatible, the pump should be drained and refilled with the compatible oil - though some shops don't do this, and it still seems to work.

The hoses should be replaced with compatible hoses - apparently the R134a molecules are smaller, and leak through the R12 lines. Though some say the oils in the R12 help plug the "holes" and they don't leak.

The seals are apparently not compatible, you can get in there and replace every seal (the seal kits are cheap, the labour is a bit time-consuming).

Since you will be cracking the system open to do this, the drier should be replaced as well.

I'm running used R12 lines and pump on mine. Pump was drained and filled with the proper oil. I replaced all the seals as well as the drier. It will have been in for a year come August. Still working.

That's the info I was looking for...Where can I get seals, lines, and a drier? I assume the shop that fills the new system could replace the oil or is that something I do?

I have everything needed for someone to put ac in their truck. PM me if youre interested. Everything worked fine when removed, turned my truck into a refrigerator when on full blast. Just removed it for the simplicity in the engine bay. Will sell as a whole or will part it, just hit me up.
