What is your question?
My 1999 Buick Century blower fan only works on HIGH. I beleive the issue is the heater blower motor resistor. Where is this located at on the 1999 Buick Century?

There is a fuse labeled "low blower". This fuse controls all speeds except high. Check that first. There is a separate fuse for high speed. If the fuse is good, the problem is probably the resistor module. It's right against the firewall behind the blower motor.
