Weak screen vents

The screen vents seem very weak. With all three heater control knobs turned fully clockwise ( max heat, max fan speed and all air to the screen) there is barely any air coming out of the vents. Hence takes ages to demist. Air con does work and helps speed the process up, but the vents are so weak.

Does anyone know if this the same on all S2s or a known problem which can be fixed ?

That happened to my Exige S about two weeks ago and I was going to send it back to the dealer for a warranty claim for fan failure but the next day it burst back into life again. Still works at the moment.??

Do the vents work on the other direction settings?

Can you hear the fan?

Maybe one of the air ducts in the front clam is dislodged

Mine did that, got the whole heater matrix replaced under warranty. Get it done ASAP.
