My ac/heat Blower would only work at certain speeds, but suddenly will not blow on 2009 Chevrolet Impala
Could be a blower resistor, wiring or switch. If it stopped completely now you could even have a motor issue. If you want us to check this out please call 313-562-7022 or schedule an appointment on line at StansGarage.net. I am sure we can diagnose it and give you the answer you need.
