Hello - I have attached the info you requested...you didn't specify which engine size so I went with a 3.8L VIN K....(the VIN is the 8th digit of your VIN number) I gave you the procedure on blower motor replacement. You most likely cause for the fan speed is the blower resistor is bad. I have also provided that for you.
