If you are not getting heat, and you know the heater valve is working, you may have more air in the system than you think. If your thermostat is stuck closed, you'll have difficulty bleeding it properly. Change your thermostat.
yes the fan does usually turn on for 30 seconds when the car is cold as a self check. He did bleed it five times, so I dont believe that is his major problem. I believe its the fan or fan switch
Always Mod!!!
