2004 EB Explorer
My defroster in my 04 EB Explorer is not opening, I know its operated by vacuum, just not sure where it is located. Ive opened the glove box and found the control valves for the sources of heat but the defroster. I can hit the defrost button and hear a lil noise but not like the noise from the other controls. Where is the vac. control for the defrost located at?
