Hello, This may be caused by system being low on freon. That would be the first thing iI would check. If not low on freon the it may be thedriver side air mix actuator, remove the close out panel on the driver side, at the center you will see two electric actuators, the lower one is the driver actuator, Move the temp from 60 to 90, Watch the round part toward the top of the actuator, it should move. Hope this will help you.

Toyota D4D 2007 Verso Side Blows Cold Air driver side warm in passenger side

the best first thing to do is check for a rodent nest in your system, look into the hvac air intake which should be under the cowl cover on the passenger side. if there is debris in there you have a rodent nest which needs cleared out. if your vehicle has a cabin air filter this is where the intake for the hvac is.

Car heats up the steam is on the drivers side

Your heater core is probably on the drivers side. It may be leaking or one or both of the hoses connected to it are leaking.. Is there water and or antifreeze leaking on the drivers side floor. The heater core is a small radiator through which air from the blower passes to warm the car when it is cold. they are not too expensive for the part, they can be hard to replace.

99 deville,cold air on pass. side warm on drivers side

There should be a nozzle on the left passenger side that has blue for cold and red for hot so if there is a light on the nozzle all you have to do is turn it to cold if you want it cold. Caddy's have dual heat so you can change what you feel coming out push the nozzle in and the light should go off. Therefore making the car on the same hot/cold.

Passenger side only blowing cold air.

You need to replace the "blend" door actuator motor on the pass side. I recommend getting that from your nearest gm dealer to ensure proper fit. When you adjust the air from cold to warm to hot, the blend door moves to direct the right amount of cold, or warm, or hot air your desire on that side of the vehicle

I had same problem on 2000 Lesabre blowing cold on passenger and warm on driver. I fixed it by adding more freon even though it had 28 pounds of preasure. Now it works great!
