simply remove the old one and fit used one in working condition...believe me it's easiest to do...I done that and no more problems and they are cheap enough from scrappies

cheers mate i think i might try that i can only try lol regard scott

Burning smell may just be a bit of excess oil getting onto the motor commutator and brushes.
It'll probably go away in a while.

why do it cut out only on speed 4 (brianmoooore) cheers scott

Only on speed 4 would indicate its a problem with the heater motor itself and not the resistor... the fan is run off the resistor on speeds 1-3, plenty of heater motors around. Try a scrappy, or if in more of a hurry I got one from e30partz.com which works grand - probably a little on the expensive side but I got it quick and they delivered to me in Ireland cheap enough so was happy with that!
