Heat Excessive

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 the following:

* 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.
* A binding or obstructed temperature air door.

A hot air leak from the engine compartment to the blower inlet is also a remote possibility.
