So I woke up this morning walk out to my car and as it was a beautiful day rolled the windows down. After work tried to do the same thing just to find out only my driver side window rolls down. I own an evo 4, any ideas?

 

Child safety switch?

 

^ Cycle the little button next to the window controls (the child safety switch). Its happened to me a few times

 

Agree with the two above. Have had that happen to me before in other vehicles, you just dont realize you bumped the switch.
