Q: Air Conditioner on 1999 Nissan Sentra

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
My air conditioner only works on number 4, the highest it can go. What could be wrong with it
(1) Answer
This is likely due to a failed blower motor resistor. The resistor controls the speeds 1,2 and 3, but not the highest speed.
