I think this is a known problem.

I can't really investigate till it gets warmer but the blower from dead cold 1deg or lower SOMETIMES buzzes like a cricket, turning the fan higher speed stops it.

I've heard it can be due to water leakage on the blower, might need removing and cleaning

any thoughts

I found that removing the cabin air filter, I could have a look at the top of the motor, a little bit of rust on the top spindle, managed to squirt a bit of PB blaster on the top from the slot, not sure what that will do or help,
it was a bit hit and miss becuase the straw wasn't long enough, but I manged to hit it, cabin smells of PB blaster now LOL

I did the same thing and the excess oil mixed with the carbon dust from the brushes and shorted out the commutator. The fan ran fine for a few days and then would only run on low speed. Higher speeds would trip the over current protection in the speed control module and shutdown the motor.
I had to take the motor out and flush it clean with carb cleaner and compressed air.
