When checking, the engine must be warmed up and the ignition on
Does the air blower work on all four stages?
At the 4th stage of the blower, turn the left rotary knob fully to the right - after a short time, only cold air should come out of the holes, otherwise the air mixing damper does not close correctly.
Are all vents supplying warm or cold air?
Does the up and down air distribution function?
