2012 Toyota Sienna - AC on one side

The air conditioner isn’t blowing real cold and mostly only working on the passenger side of the vehicle. I have tried recharging the system but hasn’t changed anything. What should I check or try?

The problem may be a faulty blend door actuator for the drivers side.



plus one on what Tester said . Check around and see if there is a reset procedure for the blend doors on google .
