Q: A/C won't turn off or lower from high

asked by on July 06, 2016

About a month ago, I turned on my car and the A/C blower was on high ("4") and I was una le to turn it off or lower it to 1, 2 or 3 (that is, the knob moves, but the system doesn't respond.) Fortunately, it cools, so my problem is I can't turn it off or use tge lower settings. I thought aboutthe blower resistor, but am not sure that helps the on/off issue.

My car has 55000 miles.
My car has an automatic transmission.
