Just in case this is helpful to anyone...This car had 2 separate Bosch fans with their own motors. The PVC heating system box had been frankensteined with these fans glued, taped, and pop rivetted in there. I had to take the whole system apart and refabricate the box using a second donor box and the expected fan set up, which can now be accessed from under the wiper, like it is supposed to be.
