Heater blower resistor

blastersump · 18-11-2007, 17:50

Hi all, my fabias air blower is only working on posistion 4, reading the threads it sounds like the heater blower resistor, would an independant garage fit this for me, or would I have to spend a fortune in a main dealer.

I'm sure a decent independant garage will fit it for you. Not neccesarily going to be cheaper as they may not be entirely sure of how to do the job and over quote for the time taken to cover their backs.

It's a common problem - setting 4 just has the full voltage applied, and 1-3 are retarded by the resistors. As I remember with my VW Polo, VW insisted that the job could not be done by anyone else as they had to be VAG-approved resistors. I cannot quite see how this could be the case though.

I had the identical problem on a GM car - after a forum search I bought the resistor pack from the stealer and it was a really simple matter of unscrewing a cover, unplugging the obviously burnt-out resistor pack and plugging the new one in.....

Hello and welcome.

new poster here ,
real stupid question time, so please feel free to slate me after.

So I take it from the about post, you can only buy the resistor pack from a dealer.

Cheers John

May the slating begin

I wouldn't say you deserve to be 'slated' for the question, it's perfectly reasonable. If I were looking to buy one then I would go to a main dealer as it is perhaps one of the less likely parts you'd find third party.

I had this happen on a Nissian Micra about 4 years ago. As said the top speed (Position 4) is just the full power applied to the motor. The other speeds are knocked down by going through different resistors.

It also had a little PCB with burnt out reistors on it. I just measured their values from a working mates car with a multimeter,remembering to subtract any test lead resistance and I just replaced them with 5 watt resistors of around the same value.

The resistor values on the Micra were 0.8 R, 0.9 R and 2.2 R. But the switch used some resistors in series for different speeds, so the total resistance worked out as :-
Position 1 (2.2 + 0.9 + 0.8) = 3.9 R
Position 2 (0.9 + 0.8) = 1.7 R
Position 3 0.9 R

Total cost of repair was about a pound. I'm not too sure what makes a VAG approved resistor but I bet the real part is loads more than £1.
