Try checking your circuit breakers largefuses or relay switches for front power windows.
If it both windows at the same time, it is likely to be a fuse related to the windows. Check you manual and/or fuse box for blown fuse and replace.
blown fuses, dirty switches, bad relay, broken poer lead to switches.
Check that the wire that controls the seat adjustment has not been cut through.
Check the switches make sure they are good. if they are then the problem is either the window motor or the window regulater. Maybe a bit obvious but just checking - If both of them are not working then check the isolation switch - its the extra switch on the drivers panel that stops the kids from playing with the rear windows, it should be in the up position. good luck.
If both front speakers are not working, then either the fade control is set to rear speakers only, or the front speaker plug has fallen out - very unlikely. Check the fade control, first. Or, I suppose a particularly loud blast of music could blow both speakers at once . . .
It could only be either a fuse, the switch/or wiring, or the motor burned up. I would check the fuse 1st.
I would suspect the connections at the drivers door switch. Make sure they are tight and clean. Most switches can be removed without removing the door panel. Mark
Check wiring in door jam to door.
Either the motor has burned out, or you have blown a fuse. Check the fuse box first. The owners manual will have a diagram for your fuse box.
You either have the lockout on or you have a defective master switch.
Junk yard? E-Bay?
Try the switch that keeps the kids from opening the back window.
