My 96 a4 is in need of a heater blower. Im getting power to the blower motor but its not spinning. I understand that it differs from 97 and up, does that mean that I can use a blower out of a B4 audi then? As well as the double screen climate control (mine has display issues, sometimes it goes blank)? Also what other things are different between 96 and 97-01 b5's besides the engine?

Pretty much all the AC and climate control is different as is the keyless entry, the wiring for the powered drivers seat is also different.

I think the B4 Audi 90 fits, I looked at a pic on e-bay and it looks similar.
