Blower motor works some of the time when it does work it works on all speeds. When it does not work every thing checks good, when it works you can pull out all three relays and it keeps working. Is this a resistor and if it is is there morte than one and if so with one would it be. Also my wife said that when she uses the brakes the fan quits working

Yes I have a multimeter manual dual control. I have found a resistor at the bottom of the blower motor but could not see one above it. For a little more info my wife said that this has happened with the ac as well
