    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?

    Thanks!!!

    What's your engine temperature gauge at when it's blowing cold air?

    It's the hot engine coolant flowing through your heater core that warms the air in the cab. Cold engine = cold air.

    It warms up to normal temperature within a few minutes. I get hot air to flow into the cab but only after moving the temperature dial back and forth a few times.

    Sorry, I hit enter before I put in the full title.

    Here's some eye candy to mollify the hoards:
