Default 1993 Corvette Heater Problems

Sure could use some advice. My 93 Corvette with automatic climate control will not put out any heat. The AC works fine... The Heater hoses are hot. Was told to check the Blend Door.
How do I do this and where is it located.

Have you run the diagnostic?

Had a very similar problem with my 93. Hoses were hot but little heat in the car. Turned out that unhooking the two heater hoses and using a water hose to flush out the heater core took care of the problem.
The heater core can accumulate deposits over the years.

Thanks,

Mike
