I managed to find two valves. The first valve was in the front side closer to the bumper. However, the recharge hose wouldn't fit. On the other hand, when I attached the recharge hose to the nozzle in the back on the passenger side, the pressure readings kept oscillating back and forth between low and high.
Just to note, I had turned on the engine and turned on the cooler to Max A/C like the directions on the can told me.
Thanks

AC should not be charged or repaired by people that are not trained.
How do you know that you need a charge any way?
Do you know the exact amount to add?
The valve that it hooked up to is the "Low Pressure" service port and you seem to have a problem.
If you do not want to be hurt by this, get it done by a Pro.

You found the right fitting. 134A uses quick disconnect and they are different size for high and low. Always have engine running as pressure can be over 100 psi when not running. Connect as directions tell you and hold canister according to directions, probably upright to get gas chsrge. Open the valve slowly and keep the pressure below 50 psi. The oscillating should stop and continue adding refrigerant till pressure drops to about 30 psi all done

The low pressure is the smaller connector, the only one the cans you buy will connect to. The low pressure side is the side that gets cold, the high pressure gets hot.

the high side and low side are different sizes. the high side is for pressure and the low side, which u referred to be on the passenger side, is the part where u put in the freon.

Your low side is always the larger hose
