Hello My name is Angel
Have you tested to see if you're getting 12v to the grid?
Ok, you must check to see if power is coming out of the switch, remove the center bezel covers, those are the plastic pieces around the a/c controls. once removed you will see the screws that hold the defrost switch to the dash, remove those screws and you will gain access to the defrost switch,
Then with the key on, test for power on both sides of the switch. T
here should be power on both sides of the switch( both terminals ).
If there is only power on one side your switch is bad.
If there is no power on both, you have to check further, make sure there is not more than one fuse.
also make sure the fuse you're testing is getting 12 Volts.
