Your front blower motor has gone out. There is a front and a rear blower motor.
Your air conditioning cool air is routed to the various vents by routing doors. A malfunctioning routing door can be stuck and remain closed.
My 1998 Civic EX engine (CA emissions) vents the upper valve cover into the air intake for combustion. I could not locate a traditional Positive Crankcase Ventilation (PVC) valve on my vehicle.
you need to replace your heater core that smoke and oily film is anti-freeze
yes
a person satnding in the way of the vents
The flap that directs sir to the selected vents is jammed or broken...or the switch that controls it is.
Fuel level, heat or air conditioning up, both high and low, high only, floor only. Center vents are for air conditioning output only, no heat. Heat is designed to blow out side and floor vents only. NOT center. Center is only for air conditioning or summer vents.
it is a vent that is in the center obviously
To remove center air vent s a t20 tool is needed. Unscrew, climate control unit and compartment. After it is pulled away, their vents are exposed. To remove air vents unscrew bolts and pop out of place.
check to see if the controls for the vents are working, there is ususally a vaccum control unit and it may mot be working on the rear vents. hope it helps. duboff
vacuum leak?
