Hope someone can help
Ive got a 2001 ford focus elle and the outer 2 grilles/louvres for the heater blower dont have any ai coming from them, The inner 2 above the stereo are fine ive open up the dampers on them all and nothing, Ive shut all bar 1 of the outer ones and there is a slight bit of air but nothing to write home about

Any ideas
Cheers
