So that fails AND can't be replaced without removing the dash?  What kind of trash is this?  o_O

 You have to remove the hvac control assembly to remove the dash.  not the other way around.     

It's still a hassle but not on the same scale.

Oh, that sounds normal-ish.  Still never heard of a cable-driven unit failing on things that aren't Mitsubishis but there's a first time for everything i guess.

I haven't had a failure first hand but I think what fails is the two small knobs for the electrical switches break,  and the way they are manufactured it's not particularly easy/possible to just epoxy them back on.   

I don't know why they break,  if they just become brittle or what.    I do know that my Montero came with a replacement assembly already installed..

Thanks to a tip from Toasty I checked the heater core pipes in the engine bay and they are brass.  Going to start tearing down the dash and then take it to the local radiator / heater core repair shop ( 12 miles from me ) to have the brass one pressure tested, cleaned and repaired if needed. I will be replacing the hose in there along with a new OEM AC control unit if I can find it for the said $120. Thanks to everyone on this forum for the wealth of knowledge. I appreciate it a ton. If I make it to Overland Expo I will buy you some beers!
