Thread: Blower motor resistor issues

we replaced the blower motor resistor in my 2000 grand prix twice now. the first time we replaced it the fan worked on 1, 2, 3, and 4. but not on 5. the after 3 days it went out so we replaced it and again it works on 1,2,3,and 4 but not on 5 but there is a super glue smell that fills the car when i run it for any amout of time. the rear defrost works fine and no coads are coming up. any ideas on what this might be?
