Why is my blower fan not blowing air?
The blower fan resistor is a simple electronic circuit that changes the resistance of the current sent to the blower motor, and enables multiple fan speeds. If you find the blower fan works, but only at a single speed setting, the blower motor resistor has probably gone bad.
What happens when the heater on a VW Beetle stops working?
At this point, the blower motor blows air across the it and the newly heated air blows on to the driver and passengers.

What happens when a car thermostat goes bad?
Sometimes when a thermostat goes bad, it stays stuck open. This allows the coolant to continuously enter the engine. When this happens it’ll feel like the heat is barely working, or you may notice that it’ll work if the vehicle isn’t moving, but if you get on the highway it stops working.
