vents don't work
 

Hi looking for advice on where i can look to fix my vents
when i press the vent button
the temp disappears on the temp selector
and no air comes from the vents

can anyone please help me figure out where i should start to look to fix this

the temperature will disappear while on vent. The blower fan should come on though.

ok, well i know that isn't a problem
when i do vent the fan is on
but it still comes out under the windshield
no air blowing from any vent

The levers under the dash may be sticking. Does any air come out the vents on "ECON" or "AUTO"?

no econ and auto come out at the feet as far as i can tell

is there supposed to be vent action on them?

When I press "vent", the floor vents open and blow relatively cool air. Nothing else happens.
