    Default None laser related - Transistor help

    all the blowers/fans have died in my car ive traced it back to the resistor pack.

    did a google search but nothing, number on this transistor reads

    F n506ab
    75344g

    anyone know where i can get one?

    Should do, just make sure you check the pinouts

    I would check the blower motor too, the transistor pack generally fails due to tight bearings in the blower motor.

    The pack might also be protected by a thermal fuse.

    once i get the resistor pack working i will be checking the blower motor.

    what would a thermal fuse look like?

    Generally a thermal fuse looks like a metal canned resistor or a very slim plain ally axial capacitor, usually with a silicone compound around one lead of the component where the lead enters the can.

    If it has one I would expect it to be adjacent to the heatsink.

    ok cheers

    so how do i check that the transistor i got from maplin has the same pin out as the original one when i dont have a data sheet for the original?
