blower motor speed control parts

Post by JonMcCann13 »

I know this is a common problem but I need some help.

I know my heater blower transistor is bad. I know I can get the parts at radio shack.

What I don't know is this.

On the back side/under side of the unit ( where the leads and resistor is located) there is a small rectangular piece in series with the resistor.

Question is what is this piece. Is it a zener diode. Is it a capacitor. Is it a resistor and the other piece is a zener diode.

I've Google this problem and found a lot of broken links.

Can someone tell me what there part numbers are or equivalents. I would really be indebted to you.

Thanks
