Initially the rear blowers stopped working, then the front directional switch only blew out on the windscreen. Itook fuse out & when I put it back in it now only blows out on your face. Now the other switch only blows air out on number 4, nothing at all on 1, 2, or3. HEEEEELLLLP.
You have different issues here. You likely have a bad rear blower motor that is drawing too much current and that has led to burning out the blower resister also. That's why you lost the other speeds. The air direction is another whole issue.
