Blower motor

[jesilvas]

I don't know about anyone else, but on max ac and high fan, the noise the fan puts out makes me think it should blow a lot more air but doesn't.
is there any way to check fan output?

I made my Samsung SGH-I997 send this.

Only with an anemometer to compare against a known good fan output.

Yea. i know the resistors go bad often in the Fords. Would that cause lower than normal fan speeds?

I had on my the med-high setting not working and it turned out to be the switch. Just cleaned it. In not sure if that's your problem. That's my 2cents

Same problem here. It seems like it should be more air output on mine as well.

[jesilvas]

All my positions work fine just seems like there should be more in all spots.
I'm thinking about replacing the resistor anyway to try it. 24 bucks at Oreilly's for a FoMoCo one.
Is it easy to get the to the blower wheel to see if any of the blades are gone?

Yea but, the resistor doesn't effect the HI setting...

I'm thinking there's a physical "leak" somewhere. That is, a partially closed door, misaligned duct, or too much "blend" (too many directions the air flow is trying to support) maybe

[jesilvas]

I wasn't sure what the resistor did. What DOES it do actually
I guess to check all that other stuff, the dash has to come apart?

[NoRalPh]

The resistor limits the amount of current the fan motor gets and gives you the "multi-speeds" from a single speed motor. But Hi is direct to the motor.

I would hope you don't have to actually take the dash apart,,,, but look from underneath or feel for air where it's not supposed to be blowing. Be sure the doors you can see are moving. You sure you've got good vacuum? That's what moves those doors.

How about the selector sw? Everything connected back there? You can pull the cup-holder & radio pretty easily and get a look back there.

Ha. That makes sense now
