Fan blowing but not coming out of vents - 2005 Renault Megane Scenic

It's the vent actuator, it moves the baffle that changes the direction of the air flow.
Here is a video of a broken vacuum hose that creates the same problem.

It could also be a failed actuator.

if the ac works and the fan works in the other positions and is only not coming out of the top vents , check that the plastic pipe behind dash and is also located near fan assembly is connected to the vents that you are talking about . also check adjust ment on the vent controls to see that there is correct operation on vent controls in all positions. hope that is of some help to you

With the A/C on check to make sure the cooling fan is coming on. If the fan does not come on than you need to figure that out first. Fans are fairly common to go bad along with the fan control relay.

sounds like the blend motor from hot to cold is stuck open half way allowing both temps to come into the car.

The A/C blender doors on the 2006 Ram are defective and are prone to breaking. Call your local dealer and ask them if they've heard of this problem. My truck had the same issue and Dodge repaired it under warranty. Good luck.

blower motor fan may be bad

Vacuum hose most likely the problem. They get dry and crack open especially near the connections. Check the vacuum and listen for a hissing sound with the engine running. Don't put your hands near the fan!

Look for a vacuum leek usually in the engine compartment but it could be under dash if this was helpful please leave good feed back.

The Fan COULD be the Problem, but Fuse RELAY and A/C Control Modual Also Can Cause this. No Air Coming out of Vents Does SAY "FAN" is not BLOWING But it Can Be Any ONE of these Items that are Keepin FAN from BLOWING
