    So my air hot or cold only slightly blows while I’m driving. I replaced to blower motor resistor and that worked for a short time and then failed I swapped for a new one but it didn’t work the second time. Any idea on what it could be?

    Brand: Chevrolet
    Model: Silverado

    Often a worn heater blower fan that turns heavily will cause the resistor to get damaged. This will cause the new resistor to blow also. Check the fan to ensure it’s turning freely and most likely you will need a new one before installing another resistor!

    When you turn on the fan do you hear it running?  If the heater fan worked before I would suggest checking the speeds on the fan.    Check the connection and the ground.   The heater control switch may be going bad or had stopped.   Turn the heater switch  and see if there is any sounds.  You have probly all ready but take a look at you fuses.
