I am not getting any heat at my feet, & my windows have started fogging up. Both on 2001 Chevrolet Venture

of these things started at about the same time. I get plenty of heat up high. All my maintenance is up to date. Cooling system,brakes & etc.

Asked by for the 2001 Chevrolet Venture
Need to get a inspection done. Probably a blend door actuator issue. It can be the switch as well or a fuse.
Thank you very much!
