    Hello, thought maybe someone could tell me why a front blower wont blow on high, works great on the other 3 speeds. I thought that the high speed was direct and bypassed the 4 speed switch down under the seat? Is there 2 sets of breaker/ relays for this blower?

    Yes, it does by pass the "resistor", but when you select your switch to high that turns on the high speed relay. The high speed relay is powered from it's own 30amp breaker. The other speeds go through other relays that are powered from different breakers. Check your F1-A 30 amp breaker or fuse and make sure it isn't popped. If that is good, try to swap the high speed relay with the horn relay or something to make sure the relay is ok. ( I bet it is just the breaker)

    My 9200i has a different fuse for high speed 4 and 1-3. So check both fuses

    Usually the resistor is bad to cause that.
