Why wont the power windows in my 2004 Mitsubishi eclipse rs work?

If this problem has to do with just one window , then the windows motor has to be replaced . If all of the windows don't work , check the power cable or the fuses : there is a fuse box under the hood .

Does it set the check engine light? Can you smell fuel fumes in engine compartment? Reading the computer code will get you on the right path to find the problem. Could be loss of fuel, flooding of fuel, or loss of ignition. Need tests to find this one.
