2004 Expedition Blower motor off or high speed only
Wife showed me an issue with the HEAT/AC blower motor.
Expedition does have rear heat/ac and that seems OK.
I replaced the actuator for the blend door about a year or so ago.
Seems like that is still doing OK.
But now the blower either seems to be OFF or on HIGH.
None of the mid speeds seem to work.
Wondering if that is a symptom of the blower motor being bad? Relay? Switch maybe?
I have yet to look at it any closer yet.
Guessing a little chasing around with my multi meter will probably help lead me to a culprit, but wondered if sounds familiar to anyone??
THANKS !!!

Typical symptom of the blower resistor/control module going bad.

Ok, that's great!
Make sure to test the blower resistor to ensure you've found the problem. It's the most common by far, but there's also other things that can exhibit the same symptoms.

Put new resistor in for the wife a few days ago.
5-10 minute job, just over $20 part, went easy.
Appreciate the help and info.
Made my life and the fix easy.
THANKS !!!
Wish the air conditioning repair on my other Expedition would go this well.
