Has anyone else had a problem where fan speed 3 on the HVAC controls is the same as fan speed 2? Could this be a switch problem? I dont think it would be a resistor because then it wouldnt be working at all on that fan speed. If anyone knows the cause of this I would appreciate the help!

Well I guess I'll get a resistor then! lol

Two screws, it's comes out. Put a little electrical contact grease on it and your good to go. Just be careful putting it in. Don't bang up the new coils too much.

Well I put in my blower motor resistor and it didn't fix the problem, still thinking it might be the switch, any more ideas?

Its the switch... I had the same problem in my F-250

I'll provide feedback.

condition - blower motor fan speed same on 2 and 3 position, 1 and 4 working

2007 F150 265,000 miles

Blower motor replaced and resistor replaced - 2 and 3 still same speed
then
fan switch replaced - 1 2 3 4 speeds fixed and work correctly
