Where can I find relay schematics? My blower only works on the highest setting.

You are probably going to want to get your hands on a Chilton or Haynes manual. It will have the schematics you are looking for.

Did you ever find schematics for your blower? Do you remember what fixed it? Our 2006 Freestyle is doing the same thing.

Before wasting your time with schematics, i would inspect the blower motor resistor and connector. Inspect the resistor for continuity and visually for anything burnt, even go as far to smell it. Also inspect the connector to ensure when/if the resistor failed that it didn't destroy that as well.

if it only works on high its the blower resistor some mount on the outside most are on the inside behind the glove compartment

its must be your resitor,it went on my 04 mazda b-3000 that i had( is really a ford ranger)it was located beside the blower motor.26$ for resistor,5 mins to replace.
