Re: Renault Scenic I - Heater Fan Fix

Hi, I've taken the resistor pack out the dash on a 54 scenic II. The fan only worked on position 4. I have replaced the thermal fuse with a 192c from Maplin. Before I put it back together I have tested it and the repair works, but the resistor pack started to smoke after 5 seconds. Does anybody know if this is because there is no airflow to cool it down or a problem with the resistor pack? Any help will be very welcome.

Re: Renault Scenic I - Heater Fan Fix

I just carried out this fix, and thought I would add three things that I discovered to make it a bit easier.

1. You don't need to remove the duct pipe completely. If you remove the right hand end (where it links to air distribution box) you can gently lever it up so as to make room to get in. Its even easier to see if you have a dentist mirror type thing, and a torch.

2. If you remove the clock console as well (2 screws and 3 connectors) it's easier to get the duct pipe back on without bending or breaking it, as you can use both hands....all you need to do after is reset the clock

3. The fan itself on mine was also in a bit of a state, but I couldn't remove it, as with others, and I didn't fancy hacksawing things off.....so I unbolted it, lowered it as much as I could, and then used a pipe and some wd40 to liberally spray towards the spindle, and under the fan.....seems to work a treat.

Thanks for the help, and great fix.

Thumbs up Re: Renault Scenic I - Heater Fan Fix

Just a little note of thanks and a little tip.

There was no trod screw retaining my pollen filter cover. It wasn't missing as there was no hole for it.

Took a few minutes of trying to find a non-existent screw before I got a mirror.

Other than that I got it all done in less than an hour.

Top notch help folks.

Re: Renault Scenic I - Heater Fan Fix

as per peoples instructions about resistor pack, the first thing to check is fuses and mine were all ok, rather than pulling the dash apart just to check something that may not be faulty if you have no blowers at all unplug the connection in passenger foot well (red and black wires) put a volt meter in the terminals coming down from dash (remove white insert on plug) with ignition on and fan switch on 0 place meter on terminals when the switch is moved to position 1 you should get 12.1v and as you move switch to higher positions voltage will rise but not by a lot, if you have voltage on all positions then its the motor at fault not the resistor pack. could be water ingress from air intake as there is no cover it just goes straight to the motor or it could be clogged by leaves and other junk its sucked in, remove blower motor and try putting 12v straight to motor if it wont run replace!!!!

Re: Renault Scenic I - Heater Fan Fix

Thanks to all of you for the hints and tips on this issue, especially removing the clock display when fitting duct. Now I will try to add a little help myself:-

When removing and re-fitting the duct be aware that it can dislodge the vent 'open/close' control - it's a small grey lever that clips onto the butterfly shaft and has a slot that locates over a pin on the thumb-wheel. It can be re-fitted if you have a mirror and a torch but if you close the vent flap before removing the duct that helps avoid the problem.

I managed, with brute force, to remove the fan unit without sawing off the bracket but it moved the fan on its shaft so when re-fitted the fan was binding -Beware!
