definately the resistor pack..

if its anything like a normal foci get your head down in the passanger footwell and remove the carpet trim under there, look up and you can see the blower unit, big round thing.. to the rear of that is a small blue box looking thing about an inch by 2 inch.. replace it. behind the glove box is also a good place to access it as martysmartie said.

salvage yards are a good place for them though being a common focus gripe you might be hard pushed to get one?

try the bay bud, plenty on there..
