Free air flow may help but on one car I had water had entered the cabin
air intake and the blower motor shaft was getting rusty and binding
slightly. I just put one drop of engine oil on each bearing to free it
up.

Note: don't use wd40 or similar. You will have a supply of readily
available engine oil in the sump - use the dip stick to extract one drop

Hi,
I've tried the DIY solution but cannot get the thermal fuses soldered
without them blowing. They should be spot welded as they are at manufacture.
So I've gone to the dealer, bought another one and crossed my fingers.

Cheers

Peter.

I'm sure a cheap and cheerful solution for them but not me!

The trick is first to cut off the old fuse leaving behind most of the
connecting lead. Bend these stubs of wire at 90 degrees. Fit the new
fuse between these wires and make a good mechanical joint by bending the
wires as appropriate. Use a _high_ powered soldering iron or gun but
first make sure it's up to full heat. Feed some electrical/electronic
lead/tin solder with integral flux to the tip of the iron to 'wet' it.
Shake off the solder then put the iron on the joint at the same time as
feeding in fresh solder.

I've personally made a repair to two modules[1] in this way and advised
friends on this approach. The modules didn't fail in 5+ years[2] and/or
are still in service without problems years later.

[1] I've seen the same problems on Vauxhall and Citroen blower motor
assemblies.

[2] cars have been scrapped or sold on for other reasons

I think you are on the right track. I replaced my blower motor. The old
one would work but the fuse got hot enough to smell. When I took it out, it
looked like it had been exposed to moisture and did not spin very well.

New one works fine and the fuse is a-ok. I think the blower motor was about
$60.

New pack has lasted a week. I think I'm OK.
