Heater/blower problems. 92 escort. - escort man
Hi,
1992 (J reg) Ford Escort

Ive got a problem with the air flow. everything seems to work fine - the fan blows, air comes out the front vents (into the car) and the lower (footwell) vents but not out the top (onto the windscreen)

Well that not strictly true, if you fiddle with the knob that directs the airflow to the respective vents you can get some air onto the windscreen - as long as the knob is inbetween the top and bottom air vent settings.
There is nothing at all if the knob points to the top vent alone - even with the fan on max.

Garage has recently taken the dash off the replace the heater matrix, but could not see anything out of the ordinary ie blockages.
It was doing it b4 the dash was taken off.

Has anyine else had similar probs, it takes ages to demist the windscreen!

Thanks,
Dave.
