AC Pro for vettes?
Does AC Pro work for our vettes? I'm sure my 2001 needs recharging since AC has not been touched since it left the factory late 2000 and has not been blowing artic winds for a few months now and it has been getting hot outside. Also not sure where to hook it up. There are two possibilities; both on the passenger side of the engine compartment. One is nearer the front while the other is closer to the firewall. Thoughts?

As long as you still have some freon in the system it should work.If you system is empty,you will need it vacuumed down.checked for leaks and then recharged.It will only hook to the low-side port,which is the one closest to the firewall.

Not sure which port is the "low port" (one that you need), however, the adapter will not fit on one of them so the one that it does fit on is the one you use. AC Pro is a very good product, just make sure you read the instructions. I believe there is even youtube videos on that subject. If you over charge the system you can ruin the compressor so make sure you understand what you are doing first it really is a easy process.

I second getting gauges and doing it properly. They're under $100 and could save potential compressor damage, which would cost significantly more to replace. R134a has a pretty tight tolerance unlike the old R12...

I do not know what A/CPro is, but if you put standard r 134 in your system with the adaptor hose kit, the fitting you will be looking for is the one just behind the battery closest to the firewall, if you have a set of gauges, one side will go to the front more visible line connector, that will be your hi side line, never try to add refrigerant in this port, the low side is where you want to put the refrigerant, I do not recommend using any refrigerant with a sealer in it, this is a quick fix and a long suicide, many shops will not work on your system or they will charge more because these sealers contaminate and damage their recovery systems, If you do buy a set of gauges, the pressures you are looking for are 28 to 34 on the low side and 225 to 275 on the high side with the fan cycling to control the head pressure, in addition you will be looking for moisture to accumulate on the low side line leading to the compressor, this system takes 1.63 lbs of r134 converts to about 24 oz, or two 12 oz cans if you have a U/V light you can buy the stuff with a uv dye in it to make troubleshooting leaks a little easier, In my opinion a vacuum pump is a nessasary need for this kind of service work. good luck.
