Blower Motor Resistor???

I have a theory that my Heater-AC blower motor might have a bad resistor. Could somebody confirm if this symptom is typical of a bad resistor?

First off, I have a 2008 6.4L F250 and the problem I'm encountering is that whenever I start up the vehicle the blower either works or it doesn't. Your chances are 50/50 most of the time. If it failed to start blowing air initially,often after the truck has been running a good 30 minutes or so, it will kick on all of a sudden. But if I turn off the vehicle and start it again, it's back to the 50/50 cross your fingers.


Has anybody had a similar issue with the blower in the Super Duty? And if so, is it a cheap fix of replacing the blower resistor or could it be more serious?

Thanks,

The resistor only controls fan speeds. If it dies, you will have your high fan setting, none of the other settings will work.

The fan blowing is all that seems to be the issue. When it randomly works, you can adjust the speed between low and high and it responds accordingly. But until it magically kicks on, all you get is just the "drip, drip" of heat coming through since nothing is actually blowing it.

I've been lazy and haven't replaced the resistor yet. Time for a visit to the local Advanced Auto store.

In all honesty, I've been a slacker with buying a resistor and seeing if swapping it our resolves the issue. Since I telecommute from home, I've not been subjected to a lot of cold driving days. So my issue still remains with the blower only pushing out heat at random times.

Overall, from my research, it is one of two issues. Either the resistor needs replacement ($25.00 from Advanced Auto) or the whole blower motor needs to be replaced ($$$$ from whomever).

As soon as I get my lazy butt up and order that part (along with some other stuff to do a tune up on my wife's car) I might be able to confirm/deny that resistor as the culprit.

What is the location of the resistor? I have similar issue with fan only blowing on high and am going after part soon. Thanks.

It is in the worst possible location that isn't access friendly.

Open your glove box and squeeze the back section of the glove box so it completely drops
down. You should now see the area behind the glove box with cabling
and such. To the right and slightly around the corner is where the resistor
is located.
