If you look under the dash on passenger side, you will see a wire pluged in directly under the glove box. Push the connector in all the way and then try useing it on the other fan speeds. I'm on my second Colorado and I have had the same problem on both of them
WOW!!! thanks for that tip of the loose wire!!!! I am sooo happy now!! I was about to go on a long trip and #1 didnt want to have to ride with it on high the whole time and #2 didnt want to ride with the windows down on the highway (bad for gas mileage)
