well to day off alldays my aircon fan speed only works on fullblast, the temp settings still work as normal, but the blower dont work on 1-2 but works on 3,

im thinking fan speed resistor,, but since i havent come acrose this prob at work im hoping sumone elce has and no a fix for it, or eny idears,

thats usually the resistor pack, as mentioned.

the fans are pretty asthmatic, but this symptom matches a dodgy earth as well as the start of bearing failure. If it starts blowing fuses on the top setting but not on the first and second its the fan motor.

Is it an easy job to replace?

thats usually the switch contacts not playing the game or the earth connection on the fan motor. Easys a relative term, I reckon its all easy in a shed class. its not too bad in a D1 either.
