So , you dont like heat?
my guess is you selected, cold with the cold lever. from hot
and it still blows hot., right?
that means the (depend on year, and submodels) if car
has hot water valve or hot damper
but really dont matter, one or other is dead. and stuck.
i login to alldata.com and see ,bingo a valve. water valve.
it has , a valve lever. and when you move dash lever the valve
lever most move in direct proportions.
if not the cable is bad. (busted) 4 ways possible. but is obvious.
this car has auto or manual A/c dash controls. options.
so that has bearing on the fix.
and aux, heating option. which i ignore here.
the abvious:
the cable at dash , fell loose. clips)
cable at end, valve, same. as above.
cable sheath not clamped and just wiggles,, messing up action.
the cable inside is snapped.
