Last year my heater blower packed in on 1,2 and 3, but 4 was OK, so a chappie who worked in a Ford workshop gave me an old spare resistor thingie which when I swapped them over started up 1,2 and 3 again (as well as 4).

It lasted a year, then last week went pop again (1,2 and 3 off, 4 OK). So I bought one off Amazon (just ?8) for Ford Focus 2002 and in it went and all started again.

Yesterday, got in the car and 1,2 and 3 have gone pop again, but now also 4 has gone as well. Checked the 30amp fuse (changed it) no joy.

If I get another resistor and change it again, will this do you think, make all 4 work again? I'm thinking the resistor has lost the loop to all 4 settings maybe?

I know nowt about cars and mechanics so thought I would ask if anyone has an idea why all 4 have now stopped blowing and the likely reason & solution.


Cheers.
