Worked out a Check Engine Light Code when we started to work on why the cruise control won't work. Took off the dash board cruise control on/off switch and must have shorted out the relay or fuse because now the little green light does not come on and I can't use the electric windows. Every thing else electrical works fine and there is no blown fuse that we can find. What did I do and where would I find the relay for this switch if it is indeed that.

Are there 2 O2 sensors on this car? I know there is a O2 sensor on the front manifold but is there a rear one like the 1996 and up?
