Hope this help

Double check your coolant level. If it is a little low this will drastically effect your heat. Feedback and votes are appreciated.

Hi there,

The heater tap or the controller may have failed, to do a basic check, with the heater on& the engine at normal operating temp, both heater hoses going into the cabin should be hot to touch, if not there is no circulation through the heater and this will be the reason there is no heat in the cabin, check this out next.
