Finally something broke

[jambo101]

The first thing outside scheduled maintenance is the knob that controls which way the heat comes out of which vent,it seems to have become disconnected from whatever it was connected to, after 220K thats not bad reliability.
Any one else have this problem or know how fix it?
Thanks
Its the one on the upper right with the A/C button in the middle=

Check under the dash for the cable connected to the air box. I think I've heard of it coming disconnected.

Hi jambo.. I have the same issue.. I took apart the dash and my issue is that the insulation came out of its mount and it get stuck some times..

The cable assembly can be easily removed from the control knob, the issue is finding a way to disconnect it from the hvac box deeper inside the dash with minimal disassemble..

Anyone out there has any suggestion(s) for us?

Thanks for the pics CB. its clearly a job thats beyond my capabilities and if taken to a mechanic looks expensive to repair. fortunately the position seems to have locked in the defrost/ foot position,i think i can live with it.

Looks like a bomb exploded but I think if you search for a procedure youll find its not as hard as it looks.

When it's on one of the defrost settings, doesn't it make the AC run?

I thought I remember reading that's how the Yaris works.

[jambo101]

Yes it will cycle on and off, not sure of the frequency but that defrost/ foot position has been my basic default setting since i bought the car new,doesnt seem to be a problem.

Yes AC will run. Most cars are set up like this.

I'm sort of the same way in that I'm almost always running the AC.

Defrost off on my 09 Yaris: 36 mpg summer, intown driving.

If I forget to turn the defrost off: 32 mpg ditto.

Fixed it, evidently a cable came loose, the mechanic re attached it , charged $45

Hi Scott...

Based on your experience, is there enough room where the other end of the defroster damper control connects too between the haves of the HVAC body(see pic) to unsnap the control to remove it with our having to take maybe the one half(right side) apart?

And if so, do you know where the snap legs are located on the end so I can get a good idea if I can reach inside and press the hold to un latch the control end?

A reasonable happy ending! :clap:

[inamoto]

interesting thread, I too was having the same problem

[CB900F2]

Hey all.. Wanted to see if anyone has been able to replace the Defroster Damper Control cable assembly with out having to take apart the entire dash and top dash cover??

Mine finally fully gave out!.. So I am forced to replace it now..

Thanks all!!!

Mine does this every 1-2 years. Just reattach it, takes like 10 minutes. Haven’t figured a permanent fix yet.
