yeah, it sounds like you have some current leakage and your a/c unit is pulling more than the fuse can handle. check the whole wire, not just the connections, you could have a skinned or burnt wire that is causing the current leak
Moved on to bigger and better things. the ride: SRT4 with 230 whp stock!!! i loved the focus but this one is just a better car for what i want. not so stock anymore. pushing 307whp/301wtq @ 19 psi.
