09 Tahoe LS - No AC

[bigpappa318]

I have an 09 LS with manual temperature control dial, not digital. A few months ago, the rear AC fan speed would only work at the same speed as the front AC fan speed. Recently the rear blower quit working all together. Rear blower motor was not turning. I replaced both the rear blower motor and blower motor resistor. No change, still not working. I then removed the front HVAC Control panel (the knobs to turn on the AC and blower motor speed dials). When I removed the green wire harness from the back, there was one pin that either was broke off, or broke off when i removed the harness.

Now I don't have front AC either. The light blinks a few times and turns off. Any ideas on what my issues are before I continue to spend money replacing things I don't need to??????

Thanks in advance!
