I replaced the motor blower heat resistor on my focus mk1 focus last week.

This got the fan working again on all its settings, and the AC button lit up again.

I replaced the pollen/ cabin filter too.

I thought all was good  - however, now on the lower fan settings there is a fume-like burning smell coming through the heater vents a few minutes after the fan is on. 

 

But if I switch it to the max/ top setting it seems to stop the burning smell (I'm assuming that is a different circuit as the max setting always worked before the resistor was replaced).

 

The air con probably is empty, but that shouldn't give off a burning smell when its not engaged right?

 

Any idea what the issue might be?

 

Thanks!

Had similar on 2002 Focus 1.6,could be the new resistor heating up and probably 

smell will stop after using it a few times.

Also after a year or so of using new resistor i had sizzling and burnt electrical smoke

coming from passenger vent,never happened again next time i used it and all 4 settings

worked fine.

Thanks.

 

The smell is a bit toxic - so just wondered if there was anything else it could be?

 

I didn't want to burn it out after just putting it in  :biggrin:
