Hi,
Yesterday I noticed that my cluster temp gauge was bouncing from normal to C back to 3/4 way to H and then back to normal. It never reached hot.
Now I have no heat. Does the temp sending unit regulate the flow of heat?
I bled the system just now and there were a few small bubbles and then a huge burp but that was all. Still no heat.
If the sending unit does not regulate heat then is it the thermostat, water pump, temp sensor or even heater core?
I have read that if it is the water pump or thermostat, the vehicle should overheat and it isn't.
Also, there are no leaks.
Any and all help is greatly appreciated.
