I've lived with no AC for about 2 years. Now that I have a baby, I need it to avoid accusations of child abuse.

This is for a 1990 350sdl. Here are the symptoms:

-No A/C (even though it was charged; converted to new system in 2003)
-the defrost vents won't close
-the center vents are weak
-No heat , just the fan blowing

And honestly, I don't know what all those buttons mean. What is "EC", does the shaded arrow mean "on" or "off"?

By the way, yall say hello to Emily! Had she been a boy...she would have be Horhe de Cemento
