Bit of a strange issue with my E36 Blower motor it seems to work intermittently. At first it would only work for a few minutes when the car was started on the highest speed so i changed the Final stage resistor for a working one from another e36 which i know was working perfect. Put it into the car and it works on all speeds now but again only runs for a few minutes and stops.
Its a basic analogue system not the climate control when the fan works it sounds perfect not like it is worn out or damaged. Anyone any idea what the issue is?
