Why would the drivers side of my car have hot air but the passenger side has cool?

I used EZ-chill but that didn't make a difference. My moms 2005 Toyota Avalon has hot air coming out of her side even though the air conditioning is turned on. Only cold air comes out from the passenger side.

    It seems that the refrigerant was not "low".  So now you MAY have too much!  Just adding refrigerant without using the dual-gauge set to read the a/c system LOW and HIGH pressures is a big mistake! 

    I'm not familiar with that car's duct system, but likely some internal "door" is not operating properly.  You need to get a service manual and see how the duct system is made.

    You have a bad drivers side blend door actuator. Do a search on youtube for replacing it.
