I installed a aftermarket radio and my now I have no air through the vents on heat or AC. I thought I must have disconnected something running the wire harness for the radio. I took out the glove box to get a better look and didn't see anything. I've checked my fuses, did a hvac reset. The blower comes on and I can hear the actuator when I change it on the control and I can see it change positions under the dash.

Well, it could be a coincidence and the blower motor resister died and needs replacing.
