Heater / AC control getting reset ?
'94 2500, AT, 5.7L v8, PB, PS, Ext Cab, AC, etc...

When I turn the truck off / on, somehow the setting for the heater control system gets reset to:

Fan = Low
Temp = Mid range between blue and red.

Even if I have the AC ON and Fan set on high, it some times gets reset. Not all the time, only sometimes.

Same if I have it OFF, sometimes it gets reset to Fan = Low and temp = midrange.

This is annoying. Why is it happening ?
