Hi all,

Recently purchased a Fiesta 1.25 very happy, only slight problem, the 1,2,3,4 fan speeds, only 1 and 4 seem to work, any idea's?

Cheers in advance guys

 

Almost defo the resistor pack, not sure where it is on your car though, try looking on the heater motor itself.
The resistor pack cuts the full voltage down for speed 1, 2 and 3, each one being subsequently high till number 4 which is full voltage to spin heater motor, at full speed.
