Hey,

Recently my '05 Mustang has had a rather annoying issue that, now that it's cold is becoming tiresome.

For some reason the fan speeds 1,2 or 3 do not work. Fan speed 4 works but you either freeze or sweat. There is no noise or anything occurring when you select 1,2 or 3.

I've done the obvious, fuses, mini-relays, all are OK and I pulled the dash and didn't notice anything obvious.

Does anyone have any ideas or even perhaps a wiring diagram?

Thanks,

Luke
