Howdy! I assume you've got the manual heater control panel with the rotary dial with 4 settings to set the blower speed? Does it work at all on settings 1-3 or only on 4?

sounds like pollen filter is blocked....motor strains trying to drag air through a wet lump of paper, other fords used to burn out the motors, looms and switches ( ask Vauxhall motor co about zafiras !!)

+1 for pollen filter blocked.

I did not had a problem with blower going too slow, but not blowing enough air. Changed pollen filter and now i can feel a breeze
