@ongosib, TomB , To be safe check all fuses in case the pwr. window circuit uses more then one fuse. Check for power to the switch(key on), no power to switch check plug and wires for corrosion/ damage. If you have power to the switch, check the switch(contacts in switch may be worn/corroded/damaged. If switch is working probable bad window motor/binding regulator, test the power window motor/regulator,replace if weak,damaged or not functioning. Find below a couple links to help troubleshoot power windows and last link will show what may be involved in replacing window motor/regulator. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
