Not a how-to or "fix it yourself" video (although the beginning might give you some ideas for what to check, why and how). This is also not the o-ring problem!
What are supposedly completely rebuilt EATC head units are available for $100 with a $50 core charge. Getting one of those is probably the most sensible thing to do.
Have I ever mentioned that I dislike automatic climate control in cars? (Ford's manual climate control system in these cars utilizes many of the same parts, so reliability isn't likely to be a whole lot different. I just prefer the fan speed and outlet air temperature to remain constant.)
Since I didn't mention some of them, one of the "great unknowns" is whether the solenoids allow vacuum flow at rest or when powered. Whether powered or not, I could not pull a vacuum on the solenoid assembly. I tried sealing the cracked plastic with glue to no improvement. And yes, "nine watts" isn't a measure of current. Oops.
I wonder how much detail Ford's factory service manual goes into with regard to the climate control system.
