Which valve is the low side service valve?

[uh60james]

I'm not really familiar with the a/c systems so I'm not sure whats what. Which valve is the low side service valve? The valve that is located on the drivers side by the resevoir, or the valve located on the passenger side by all the a/c components.

Passenger side of the engine bay above that black metal canister thingy

Actually nevermind you drive a 93. I believe your system is an r-12 system which will need to be serviced professionally. I think, but could be wrong, that the 94's were the first year for r-134a systems

ok, well so the low side r-143a adadpter only fits on the port on the passenger side by the condenser. My problem now is I put about 1/4 of the can in and the gauge reads 100 psi and the can does not get cold like it normally would. Any ideas?

Wow 100 PSI on the low side? That is very high....
