It worked on the way to work the car was shut off for about three and one half hours and when she started it and switched from the heater to the air conditioner the blower motor would not blow cool ait into the car.
What the hell does that mean. Hope this will lead you in the right direction. Heat and AC on window and floor only. Check the blower motor and blower motor resistor.
