This one's in a Dacia Duster but the same setup as a mk2 clio, probably many others too.

It's a regular failure point, (thermal fuse) anyone come up with a satisfactory solution?

make sure the pollen filter is changed regularly but they do seem to be a consumable.

Is it for the blower motor?

Yes blower motor, and I'll swap the cabin filter this time too.

This will be the 3rd one tge car has had, 1st one under warranty @ 2yrs old, 2nd one I replaced after another couple of years, just failed again. Car about 6 yrs old.

Do you park outside? Are your windscreen scuttle drains blocked? Water can build up and overflow into the blower motor. The motor still works but draws a lot more current and will burn out the speed control resistors or thermal fuse.

If you need a new blower motor it's often a right pita, buried high up behind the dash.

Yes we park outside, but keep scuttle drains clear.

So when you pour a watering can onto the windscreen the water immediately drains out from the right places under the car?

If it doesn't come straight through, the drains can get blocked lower down by an accumulation of powdery crud which makes it through the coarse grid in the scuttle and forms itself into a plug.

Hopefully it won't be this, but it's worth checking.

It drains really well thx, we have pine trees, so something I get a bit paranoid about!
