SOURCE: AC Driver side blows hot, passenger side blows cold
Try an A/C recharge. What is the temps of the discharge air from the vents?
SOURCE: 2004 toyota sienna a/c not working one side cold other side warm
there are two a/c lines that run down the fire wall under the van to the rear.right around the bottom of the fire wall the is a connection point on both lines. you will find a leak there .replace the orings and recharge system. also you will need two specail toyota tools to release the couplings.i have done this repair on several sienna's. let me know if this helps.
SOURCE: heat on the driver side but blows cold air out of
the operating flap isnt working ,but never done one as yet so i have no idea how to get to it
SOURCE: Drivers side vents are blowing
There are actuators that open the vents...im betting that side's are stuck.
