I'd be careful shorting out the thermal fuse. Something caused it to
'open' and they are installed for a reason.

If you solder it, use the 'heat shunt' method with pliers- like we
used with old fashioned transistors.
what is that then?

Hold the wire, between the body and joint, with pliers while soldering.

As Harry mentioned, wrap the wire first and 'nip it' up. The solder is
really just to stop it shaking.

Unless it overheats, the solder shouldn't really melt in normal use.

If, as it sounds, you've not changed the filter, it could be it has
overheated. Filters should be changed every year at least. They aren't
expensive- I pay between £7 and £20 or so, depending on the car.
Usually a 5 min job.
as I said the specs of the car at the time said it didn't have one being
the basic model......probably has one after all...

Even worse, the all kinds of 'cr*p', including leaves, can end up in the
heater. Often, there is space for one in the basic model - they just
don't put the filter(s) in. Worth finding out and inserting. Helps if
someone has Hay Fever as well.
