My heater works like my indicators...on and off...
Sometimes it start heating up as soon as I turn the cabin temp to 22 degrees. Other times it only work when I turn it up to 27 degrees. Why is that? Got anything to do with the heater thermostat? Water problem?

Hi Oubaas

Could be as simple as a faulty switch, or less so, could be the valve or heater core. Since it is acting up like that, my money would be either on the switch or valve/thermostat. Have not experienced this issue yet but would like to know the outcome.

Cheers
