My mechanic replaced the swtich thingy that controls the hot/cold air that blows through the rear vents. It's been less then a year and now the rear only blows non-a/c air. The A/C in the front is working great.

Is the switch thingy the root cause or is it something else? Is this a known issue? Is this someting I can replace myself? I'm trying to avoid having pay $$$ without knowing what the root cause is. Any suggesstions?


Thank you,

does it do the same thing when controlled from the front controls??

 

It does the same thing via front controls.

 

up in the DIY sticky, there is a cut and paste from the service manual for doing an actuator test / calibration of the hvac system. Try that and see if you get any codes. If you have a bad actuator it should show up with the test.

 

Tizzy,
What/where is the DIY Sticky? Is the acutator the motor that controls heat/cold air? Will it show me a 'Check Engine' light or do I need a computer when I do this?

Thanks,
-T

 

You will find the DIY sticky at the top of page,under Tizzy and other DIY.

ist a comination of pushing buttons on the heater controls and observing the light flash on the rear wiper button. counting flashes = numbers.
