So I have a 99 Tracker.
the heater is either putting out full heat or full cold vent.
it does not have air conditioning just the heater.
I have traced the temp cable down to the the Damper box and it moves the arm and is properly adjusted to give full range. the control to recirculate to open air works fine I hear it thump.
so It seems that it varies per starting cycle. So if it's working on full heat and I turn off the engine then it most likely will not be on again when I start again. I sometimes hear a thump just as I turn on the system and that usually tells me there is a change it will either change from full hot to full cold.
I have the full shop manuals for this Tracker but there just isn't enough information on what is going on inside that damper box. I don't think it has the electric motors and it's all run by cables but i'm not sure. I think the heater core is good and the thermostat is ok . it's just there is no mixing of the air with the movement of the temp slider. Im getting good flow of hot water through the core as far as I can tell.
any help would be great!!!
