Hello, I have a 1997 ford explorer with a 4.0 ohv.
I think I might have a blend door problem but no sure.
My symptoms are I only have hot when the control in set to anything other than ac/max. Once set to ac max all I have is cold air. There is no adjusting the temp. I have tried the blend door fix and I have not had any success with it.
When I look under the hood. I see the four inlet heater valve. When in a/c max the diaphragm in suck into the plunger, when the control is in any other position the diaphragm is fully extended out.
Is there anything else that might have caused this or can the blend door still be the problem.
