paxam

All
I read before on the forums that the tacoma has several known issues.. currently I am experiancing one of them.. going down the road with the vents open and the fan on I get hot air coming out when I change the heater control from cold to hot back to cold I get cool air once again.
I am curious where this controller is.. I checked the valve on the fire wall it seams to be moving. I also zip tied it closed and still I get the hot air ...
I assume under the dash there is another valve.. where would this be?


thanks
