When I bought my x the cruse didn't work then the door sensors stoped working then the only way you could lock or unlock the x was to use the remote the buttons didn't work and now nothing works windows don't roll down the back ones won't open the gages don't work the stereo don't work the power seat wont move the pedals wont adjust but the heater still works I did find one bad fuse under the dash but it didn't fix anything I dont know what else it could be please help

 

and the back up sensors don't work. O its an 02 limited v 10 all stock no modified parts on anything other than I went to a 285 tire instead of a 265 but it brought the speedometer to read right and its got 170000 miles and its white ha ha not that it matters thanks guy's

Looks like a v10 was stated

 

I would test to see if you have power going to each of the circuits. Start at the fuse then work your way thru each item to its end point(window motor,lock solinoid). Look closely at all the wires. Look for butt connectors/cuts/chaffing.
Also I'd take a look at your alternator and battery. When they are bad they can make some funky things happen.

 

What fuse was blown?

 

I would use a multi-meter to make sure 12V is over each fuse. Just ground the negative wire of the multi-meter and poke the exposed metal on the fuse with the positive wire.
