I'm having the same issue: heater blower works only on low speed regardless of the position of fan speed controller. I have checked the fuses and they are all good. Have taken out the fan controller box and could not find anything wrong in there (no burnt marks or black resistors on the pcb board, etc).
Where exactly is that relay that you have changed and fixed your heater blower speed problem? Cheers!
I have a 306 cabriolet 1994 1.7l manual. Thanks again.
