Why is my blower motor stuck on the lowest setting?
A blower motor stuck on its lowest setting prevents the fan speed from changing even when you turn the dashboard dial or install a new resistor. Replacement parts, especially cheap ones, often burn out immediately, leaving the climate control system permanently trapped on low.

“my AC stopped blowing strongly on me two days ago. The air blows really low, and it seems to be blowing air really low like if it was in a low setting and doesn't want to go up.”source ↗
