Technical Heater speeds

[dazfaz]

Fiat dablo 11 plate. Heater only works on number 4, all other speeds there is nothing. Any help with solving this problem would be a great help.

You need to change fan resistor. Look under glove compartment, you will see heater fan. There are two plugs, smaller one is for the fan motor, and larger is for fan resistor. It is very easy to remove, just unplug the plug and unscrew 10mm screw, and you can take it out.
You can see location of parts in this video

But don't worry, you don't need to disassemble everything. The resistor is accessible from below the glove compartment.

Thanks dinkocar, that was exactly what I needed and fix my problem with a new fan resistor within 15 mins. Cheers
