Question about 1999 Chevrolet Silverado 1500
It sure could be a blend gate. I have had some problems with the blower motor fans rubbing on the inside of the hvac housing too. When this happens the air will not flow to the hvac housing and then out to the vents. It is an easy check. Just pull out your blower motor and check the housing for any rubbing marks on the housing or the fan. Past that then you need to further check the blend doors or possible blockage of the heater core or A/C evaporator. Hope this helps.
