I am having issues with the master window switch. It got wet, I can hear the other switches working but only the drivers window goes up and down. I can purchase an after market part but there are two options a cheap one 50.00+ or an expensive one 200.00+ now the only difference i can see is that the expensive one is for model ex, exl, and touring model and i assuming the other is for the basic model. What if any difference is there between these models for this part. It would not make sense that it is any different?
