Heating A/C and Daytime Running Lights on 2001 GMC Yukon Denali

The rear heater and AC work fine but the front vents seem blocked as no air comes out at all, how and what do I check for?

the front blower/heater fan motor may not be working. check fuse and then see if there is power to it which is a little difficult.
