Check your under hood vacuum lines running from the motor to the passenger firewall , one is likely cracked or broken.

My air runs cold but is stuck between defrost and front vent. How to fix


Pull the control panel out of the dash and see if the mode control vacuum switch has a good vacuum source or the switch itself leaks vacuum. The mode control is what moves the doors that diverts the air flow around to the vents, defrost and floor.

Air conditioner blows out defrost vents when acceleration.


In f150 truck there is a small vacum hose passenger side up by the windshield. It's a small hose check really good they dry rot and it will cause your vents to switch. Also if your box is bad. It's next to the battery

When i turn the air on it doesn't flow from the front vents.


Sounds like the switch or actuator is not operating. Some vehicles have mechanical operators, and some have vacuum actuators. If a vacuum line is loose, it will not actuate.

I HAVE A 2001 DODGE DURRANGO THE DEFROSTER IS NOT BLOWING ANY AIR OUT OF TOP OF DASH BUT SEEMS TO BLOW OUT OK ON ALL VENTS AND FLOOR


it sounds like the switch lever for the vents, floor and defrost is not switching the vent door that goes to the defroster hose. You need to pull the switch consol out loose from the dash and follow the cable for the defrost that goes to the hose for the defrost. You might also have a broke switch that won't pull the cable enough to open the air for the defrost hose.

I have a dodge 600. when the heater is switched to defrost no air


check for any vaccum leaks, hoses leaking or unhooked, also may have a bad blend door motor. see if all other positions work like floor, vents, fresh air and recycle air. good luck.

Problem with air not coming out of vents.


Check for a vacum leak from the engine to the a/c.The color of the hose is black. Also check if the heater control valve hose is unplugged. If you have vacuum the it sounds like the door for the vent/floor/defrost is broken.
