Hot/Cold Temperature Dial not working

    Graham [OP] Pay it Forward

    Apr 8, 2009
    Western New York
    2005 4x4 TRD Black V6 6 speed manual
    I have a 2005 TRD manual shift 4x4 Tacoma

    The hot/cold temperature dial works intermittently. I start the truck in the morning to warm up and set the temp to high to defrost the windshield. I come out after 10 minutes and have nothing but cold air blowing on the windshield. I fiddle with the temperature dial, moving it from hot to cold and it eventually starts flowing hot air into the cabin.

    I took it to my mechanic this morning and he says it's working fine and can see no reason for my symptons. He suggest I wait till it completely fails to then find out whats wrong. I don't like this solution with winter rushing rapidly towards us in upstate NY.

    Any suggestions on what to check out or what could be the issue and fix?
