Blower number 4 not work

Hi all my blower on number 4 won't work, 1,2,3 all work still anyone have idea, phoned Ktec but not helpful at all just said would need car as not seen on my clio
 
Chance to be your heater resistor located on the side of the motor its a common fault tht the wiring melts on theplug
 
The resistors them selfs arnt too expensive if you get 1 from a scrapyard all mk3 clios are the same(well 2 types 1 for a climate control and 1 for just standard ie,cup ect)
 
Find the resistor and wriggle the cable, my mums heater was playing up last winter, wriggled the cable and its been fine since. Give it a go and see what happens. Saves you forking out.
