Hyundai Elantra 2003 fan blower

The blower has stopped working. Noting works at any speed. That's a
very bad moment -20°C. Where should i look first for this trouble?
What are the common parts that may cause this problem?

Thanks.

 

This evening when searching for the problem i gave a knock on the fan
motor and it started again! It seems to be an intermittent contact
problem. Somebody have an idea?

Thanks again...

 

From the nature of your questions Syl, I'd suggest you take it to a
qualified mechanic. What you're faced with is sort of obvious, but you're
asking for suggestions. No offense, but that implies that you don't really
have the basics to go any further. You'd probably be way better served by
simply taking it to a garage.

 

brushes stuck. Off hand at -20 if you had some moisture in the brsh
holder and it froze the motor would run until the brush wear created
enough gap. Knocking on the motor added a little more force to the
brush holder spring and reset them to contact the armature. The
question is if the "repair" will last or if you need to
rebuild/replace the fan motor. It seems to be getting ever harder to
get parts like brushes so you will probably get stuck with replace.
Teh thing to do now is give it a bit of time and maybe invest in one
of those 12 v heater fans. ;-)
