Question
My 1984 Eldo blower system seems to work but will not give heat. Is the door stuck on a/c and if so, how do I correct this? Thanks.

Answer
You need to replace the A/C-Heater PROGRAMMER.

If you are mechanicaly inclined or know of someone who is, You will need simple electrical schematics, Test procedures and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture.
