Does the one fan that runs all the time run with the A/C and defroster
OFF (it will run continuously with either ON).
I have seen many cars that virtually never run the fan and stay at
proper temp.
On some cars, that 'jiggle valve' is a critical air bleed that can cause
bizarre problems if not installed correctly (or without one)
