ck fuses 1st then blower motor resistor the fan motor could be any of the 3 issues
thank you, checked the fuse, its fine, replaced the blower fan relay switch exactly a year ago. could it be that it has to be replaced again? mechanics not very clever in south africa
could be switch or resistor,ck ressitance at resister it should change with each speed
