Title says it all. The heat will work for a few days. Then one day I turn it on and it's just cold air. It never stops working while driving it, it's always when starting a new drive. I've tried turning on Auto, tried turning off the entire heat and back on, turning off the temp button on the temperature adjuster, and even added some coolant to the heater coolant tank, which wasn't really low. Anybody else have this issue? Leary of taking it to the Stealership and them wanting to just replace everything... Nobody actually fixes anymore.
