2001 Toyota Highlander Q&A
2001 Toyota Highlander Question: No heat or cooling at all now; was sporadic. Any ideas on what to fix & cost?
Heater and AC no longer work - was sporadic but able to fix sometimes (not always) by twisting knob for temperature and getting it in the "right" place. Then left it exactly there and only used on/off. But now nothing works except the fan does blow current temperature air. - NChighlander
sounds like the controller contacts are bad inside the dash controls. seek a diag and est as not to waste $ - globalhelper
