The driver part of the ac is not cold while the passenger side is cold. I've checked the blend door actuator is working well and yet it was just blowing air. What could be the problem?

Good morning,

There is an actuator for the blend door. This could be the issue for the no cold air.

I attached a procedure and pictures for you to view.

Replacement

1. Disconnect the negative (-) battery terminal.
2. Pull out the passenger's crash pad center lower cover (A).

Thanks so much for your assistance. I've checked and followed this procedure but yet it's still not getting cold it is only the passenger side that's cold and I noticed a hissing sound anytime I on the A/C and one part of evaporator is dry and the order side where cold water Is dripping the normal way into the vacuum through the hose. Why is the driver part dry?

Okay, we need to go in another direction.

Do you have gauges to test Freon pressures while the A/C is running?

I think you have a Freon issue here.
