View Full Version : Blower Motor (fan speeds) Resistor Block

Anyone know what the specs of the diode used on the resistor block for the fan speeds of the heater/AC blower are? Only speeds 3 and 4 work on my fan for AC/Heat. I disconnected the resistor block and it works on full speed (4) so I know it is bypassing the resistor block. I took a pop can top and bridged the connection (bypassing the diode) so I have narrowed it down to needing a new diode but all the numbers and specs are worn off. In the OEM manual it say the resistor blocks are not fixable and you have to get a complete new one which is bullsh*t. It would be so simple to soder a new diode in place if I new the watts, voltage, amps etc.

thanks
