Hi,

 

My ventilation is alternately stuck on hot or cold. The heater and AC both work fine, but when changing the temperate it seems to get stuck. Right now it is stuck on cold. Turning the knob has no effect. Last week it was stuck on hot. Any clues? It's a 2000 legacy wagon.

 

Thanks

Just a wild guess, but is the knob broken?

 

The 'guts' in behind that grip the stem of the actual control may be busted. This happened on my ex's 99 Honda Odyssey recently (rear climate control knob).

 

Pop the knob off and take a look at the backside. Turn the stem by hand and see if it works that way.

Thanks for the suggestiong. I don't think it is the knob, as I have been able to change the temperature a few times. I turned on the heat for the first time this week and it stuck on hot for a day, then it was OK. Then it spontaneaously got stuck on hot (while the switch was on cool) but also went away. Currently it is on cool.

You may have a problem with the vent door or the control to it.

if anyone's curous it turned out to be a disconnected cable

Thanks for the feedback Scooby Dooo.

The cable from the controls to the mechanism that determines the air temp. Dealer did it for 1 hr labor charge.
