that sounds like a loose wire, or maybe the blower motor resistor, witch is under the dash behind the glove box, along with the blower its self, theres a write up here in the how to section on that, i haven't had to deal with it myself yet. search away for that one.

I don't know if this helps...on my 04 the wiring for the HVAC panel was rubbing on the dash console and frayed a couple of wires causing a similar issue for me.

he might be talking about the climate control with the fans speeds, and what not. they come out easily to inspect it and the wires. just need to pop off the panels from the dash front.
