Clarification from previous submission (10/21/14)....... heating system blows cold air intermittently when the heat is on. The system was cleaned, worked well to a short time. Within two weeks the problem returned. The mechanic noted this was a common problem with the heating control panels of the early model Toyota's. safety factor: This is hazardous in the winter, as the windows become foggy resulting in the limited visibility especially while the vehicle is in motion.

2003 Toyota Highlander 4.0 heater has gone out in this vehicle and only the A/C now works this happened right after the purchase of this vehicle and the cost to fix this is very high and should be dealt with per Toyota since it seems alot of others are also having the problem due to a faulty knob becoming loose and breaking a tiny wire.

Manual heater control dial lost function to control temperature. Heater only blows cold air. Recommendation was to replace heater control panel at cost of approximately $600 for the part alone. Labor addition charge.
