My A/C only works on high? How do i fix it? Or is it the inevitable Dealer only replacement? HELP?

Im new to the MM scene, but I know cars and parts, so Im not really sure the specifics of the MM systems like some of these other guys do. But I would start looking at the blower speed switch (in the dash) and the blower relay/resistor pack (usually in the engine compartment). The relay should be easy enough...most relays under the hood are the exact same part so you could just switch it out with another one for a quick check. Hope this helps...

Sounds like a resistor to me.
All blower motors run at one speed, the resistor is what slows it down.
Usually when the resistor burns out the fan will only run on high.

Check the search engine on this one. There's several threads on AC problems. Most common problem is the AC comes out of the defrost. Search on EAC.
