HEATER PROBLEMS
 

I wonder if somebody could give me some advice about a problem that I'm
having on the heater and defroster on my 1970 Cadillac Sedan DeVille.
When I turn on the heater or defroster they blow cool to lukewarm air,
and the interior of the car fills with smoke.

The obvious answer is the heater core. However, I've had the car to two
different repair shops. They both checked the heater core, and found
nothing wrong with it. They also checked the radiator, the hoses &
clamps, as well as the exhuast system. Everything checks out normal.

Neither repair shop has a clue as to what is causing the problem.

Would appreciate any thoughts.
