My car has climatronic so I know the fan speed adjusts from time to time but this is NOT normal! The fan speed goes fast then slow constantly and randomly without the indicated fan speed changing on the climate screen. I can hear a faint squealing sound coming from passenger footwell which I think is where the fan is located?? Has anybody come across this and what was the problem please!! Could it be a sensor sending it crazy? Or is the fan seizing up or loose??!!
