I have hot/cold air coming from the left and right most vents on the dash. However there is no air coming at all from the center vents.

Any body run into this issue.

thank you for your help.

Read you manual, while in heat mode there should be no air from the center vents---then check you temps settings to make sure both sides are set for heat---if so diagnose the duovalve, as one side may be closed when it should be open.
