Defender Air Conditioning fan switch

The A/C fan switch has 3 positions : low -mid-Hi .Low was not working in my Defender 110 .Two days ago I heard a noise coming from the fan and the A/c stopped suddenly when it was in the mid position.Now the switch works only in the Hi position.
I checked the fuse box but there is no separate fuse for the switch.
what is the solution ?

I could locate the resister pack thanks.
However I want to fix the blower, it works on full speed but it is noisy.
I suspect the bushing or bearings.

Thanks for your care

might be worth checking there is nothing in the blades like leaves etc and throwing fan out of balance that could make it noisy

if there is , it can damage the resistor as the restricted air flow doesn't cool the resistor causing it to burn out

so there is a chance the problems are linked together
