Blower motor dosen't work in sub zero temps

Hey all, I researched prior threads and didn't find anything similar to my question.

2000 Regal GS dual ACC. Very odd thing happining here, when the temp is under zero, blower motor will not work, all HVAC controls are working, (ie...auto, air positions, dual controls. etc, I know this because I can hear them changing..) When the temp goes above 0, it works like a charm. I find this to be quite weird and I know someone out there can assist me on this issue.

Thank you in advance.

That is a weird problem. You may have to take it to a GM dealership and have a diagnostics performed on the CJ2 ACC climate control system. It may just need a re-program job.
