Heater blowers

[Mikeyg345]

So the blowers on my fan control only seems to work on 4…. Any ideas before I pull the dash apart?

99.999999999% going to be the heater resistor

I replaced mine a couple of weeks ago and its blown again...? Any ideas. It was a cheapo one on ebay (£15). I read somewhere the heating fan needs replacing potentially.. Open to ideas. T6 2017 highline. The first time i replaced it, it lasted over 3 years!

Rotate the fan by hand, if it spins freely and not the slightest bit stiff then it's probably a bad resistor. Any stiffness, then needs a new fan

Zero continuity over the resistor or between the pins. Also a sorry state, corroded quite a lot!
Fan spins freely though thankfully.
