Isn't 15 hours labor around $1500 or more?
If a Dealer wants to fix the problem with everything in its original configuration, the Dashboard, Instrument Panel, HVAC Cabinet, all have to come out. The Vacuum Tank and Check Valve are both buried in the Cabinet.
I read a number of threads about this when our controls went out in 2015, and the dealer repair estimates were around $1000. Which is why I like the fix I did or one very similar to it. It's apparently a common Ford problem, at least in trucks.
I looked up some of the Ford Vacuum Tanks. They are contorted, flat things. Unsuited for vacuum, that wants to flex and flatten the tank. That promotes cracking. Look at Deep Dive Vehicles. They're all Spherical.
This is the Dorman 47076 tank with Internal Check Valve.
Here's 47077. Internal Check Valve. One end to Engine, one to Controls.
It's the one I used, with a Dorman 47150 Check Valve. The single end is From Engine Source. The two angled ends are for Control and Tank.
