Blower problem?

My number 2 setting works intermittently. It doesn't bother me too much as it's neither here nor there as a setting, but it would be interesting to know what the cause is.

Curiously, when I viewed an Albi at a dealership prior to the one I bought, setting 3 didn't work on that one!
 
Take the glovebox out then pull the connector block off tht connects to the resistor on the side of the heater. take a look at the connections as they will be melted as its a common fault i just scraped all the melted plastic out cleaned the connections up and sprayed with wd40 and all was well again,im 99% certain it will be this ,if not it will be the resistor itself at fault
 
Thanks for the help! All fixed now. :smile: could not see any melted plastic, just blew on the connector and that did the trick!
