Problem Related to Heater Blower Motor

I noticed yesterday that the blower motor for HVAC in my 1999 Grand Prix GT only works on a setting of "5". I checked it in different modes (heat, a/c, vent), and the result seems to be the same. Any suggestions on where to start looking for the problem?

if you have the manual a/c controls (not the digital climate control), you need a blower speed resistor. It's a very common issue on these cars, AC-Delco part# 15-80571, and it runs about $30-$35. Its mounted under the dash below the glove box behind the blower motor. Just follow the red and black wires that plug into the blower motor back to the resistor.

Rich,

Thanks for the info and your help.
