Between the 2 the vents in the centre of the dash (i.e. above the radio) there is the lever that can be adjusted to mix in 'some cold air' with whatever the heater control is set too. however i can't feel any difference! is this normal ...or should there be definite cold air coming through???
The cable from the lever seems to work ok & rotates something under the passenger glove box - presumably a flap in the ducting above.
all the other vents 7 ducts blow air strongly, although the 2 mentioned are the weakest - however they let a fair amount of air through so just assume this is the design rather than a blockage ...is there a way of checking, as i can see how to get access???
ps. have replaced pollen filter & cleaned out area around filter.
