Default C6 hvac control

Im getting power to my ac control module but no ac, heat, blowers, nothing is going on. Seems like a bad module to me. But before I spend that kind of money on a non returnable part I wanted to see if anyone else had this issue. Wires, harness, fuses have all been checked and in good working order. Digital loghts on unit come on. Just not turning on the blower.

My problem has been going on for months now. So ive driven and shut it off and so forth many many times. Had it checked out last week but the mech is only 80-85% sure its the module. But says and has shown me everything up to the module is fine. I sparatically get power to the blowers every so often but not a lot. It may stay working for a day. It may stay working for 30 seconds. And it may only come on 1x every so many weeks. But the digital display works fine. Never goes blank.

Basically you're saying no air hot or cold from vents. little or no voltage to blower motor. If this is the case check the blower speed control module.

Thats exactly whats happening. I can hear it kicking on in the engine bay but no blower at all. The speed module is part of the ac control module isnt it?
