Where to start!!! I tried bleeding the system no air bubbles came out of the bleeder I take it there was no air but no luck heater still not working.
I removed the valve to check the function all seemed ok the two pipes from the valve get hot I tested the function by turning the ingnition on and off ie the valve opens when key is turned on and closes when key is turned off.
Could it be the module itself thinking the car is warm therefore not diverting the hot air into the car?????? I'm bafffffffeled please somone help it was -8deg today not funny driving a cold car.
