Expansion Valve

Can anyone tell me the steps involved to replace a rear a/c expansion valve?

i have a 99 pontiac montana. the front a/c works fine, but the rear vents only blow warm air. From researching, it appears that the problem is from the rear expansion valve. I understand that i may need to have a shop discharge my freon. Can i just replace the valve and then recharge it myself with r-134a that i can buy from the store? what steps am i missing? i'm just trying to keep my costs at a minimum. Thanks.

no once you have broken the system open it will have to be ran into a vaccum before it can be recharged to make sure you get any moisture out of the system. Im sure you can find a shop to recover the refrigerant for you and then you can do the work and take it back to them to have it vaccumed and recharghed
