Excessive Heat

EXCESSIVE HEAT

The most likely cause of excessive heat from the heater system is an out-of-adjustment temperature control cable. Other related causes of excessive heat include a slipping self-adjusting clip at the temperature control cable end, a loose control cable sheath retainer or bracket at the bottom of the heater assembly, or a binding or obstructed temperature air valve. A hot air leak from the engine compartment to the blower inlet is also a remote possibility.
