Rear Hvac '01 Suburban

[Zimm]

The rear air quit working on my 2001 Suburban LS. It has the "computer climate" option with rear controls. All fuses in the blocks are good. The rear HVAC has always worked fine, but suddenly quit. My daughter claims in came on briefly when we went over railroad tracks, so I'm wondering if it has a loose ground on the blower, etc.. Is the blower located under the right rear interior wheel trim?

 

Thanks in advance for any help with this matter.

The problem was a faulty rear blower module.
