I could use a little advice on my 2014 Titan heater switch. The past few years as summer turns to fall and I crank on my heater she still blows cold air. I had my local dealer and mechanic look at it and they could not find a definitive problem. The only fix was driving her to operating temperature and then "burping" the reservoir and radiator caps. After that boom I have heat again. I had to repeat this several times last winter. Now that Fall had hit I warm her up on cooler mornings and nothing..... just cool AC to defrost my windows. I am thinking about doing a complete cooking system flush and fill maybe it might free a stuck valve? Any thoughts my friends? Thanks !
