When you say little heat, you refering to heater blowing cool air or that air flow is not present?

How is the temp. gauge reading? Running to normal temp? Does the control switch adjust the heat temp. cooler and warmer or does the heat stay at the same temp ?

Could be possible resistor if controls not working, or switch itself is faulty.
