Having problems with your 2005 Jeep Liberty ?
Blower control only works on high
\015 The blower control for the a/c & heater only works on the number four high level, one, two & three don't work.\015
Either the switch, relay or blower resistor has failed. I would check resistor and relay first. The resistor is a flat usually brown item attached by two screws to the blower box, usually fairly close to the blower fan. the relay is usually just upstream from there. Unless the switch feels sloppy, it's probably OK. If you can't locate these items, get a manual. It will help you with this and lots of other stuff!!
