Question about 2003 Toyota Highlander
I turn the heater on and only cold air comes out. The air conditioner works perfect.
It's usually broken solder joints on a cable behind, and feeding, the temperature knob.
I repaired my 2002 Highlander yesterday thanks to this site.

Wow, I have the same problem, heater blows out cold air and AC works fine. All of the whack jobs at work told me repeatedly your thermostat is bad. I changed it even though i felt like that wasn't it, and low and behold the same problems exist (no heat). Whats the next step? someone at the auto part store said try the heater Valve.
