Heater blower was working fine. After turning ignition off and re-starting,blower was not blowing out any air at all. Have changed fuse and still not working. Any ideas?

motor is shagged. its a shagged motor, your motor is shagged

or could be something else

Hi there, check the fan does not work at all by turning the fan speed control, if it works on full speed only then a heater reostat/resistor is req'd.
Another check is to turn on heater fan speed to full & using a test lamp connected to earth/chassis of car, find the connection plug at bottom of blower motor beneath glovebox, remove plug (2 wires in plug) & using test lamp, touch each wire & if power is live at wire the test lamp will light. This lets u know that there is feed/power to blower motor & it then points to motor.
If no power is present at plug then recheck ur fuses making sure that u have checked all the fuses even the fuses in the engine bay. If the fuses r ok then it would really need someone with experience to check all the system to ensure that wiring ie ground & power is present at every connection/switch.
Good Luck
Cheers

sell l have Clio 2002, its crap

Well, check the fan first - turn the fan dial & see if that does anything - Clio should have a fan dial that u can turn both ways (it can also recirculate air), so turn the dial anyway u can - if u hear a sound (like something falling, or just a noise) when u switch from recirculating to normal mode - then ur fan has fallen off it is sockets - u need to go to a car service so they can repair it.
The air conditioning pipes could be clogged with dirt, dust, whatever (the car has 10 years do not forget it).
Other then that, maybe the fan is completely broken, in which case u should still go to the car service.
