According to the RAVE Cd it's "1E3 ohms", hopefully a mathematician will be along soon to translate that into real money !
Incidentally, I went looking for my heater resistor, as the fan refused to work on maximum speed (lever right down), couldn't find it - unless it's actually inside the heater box ?, so put the dash and everything back together - and as if by magic it's started working...........but for how long :?
