Hello,
the car blowers stopped working a long time ago (during the summer) so i didn't address the issue at the time.
it is now winter and its a cold drive to work.

i have replaced the resistor but it doesn't seem to have made any difference, one thing i did notice is that my connector block only has 4 wires where as those i have seen in previous posts have 5....is this normal or am i missing a wire?

i am going to check the fan next but my question is is there a way to bypass the resistor at all?

any wireing diagrams of the heater system would be appriciated

thanks
 
Hi. :)

The manual 'twisty knob' system is the same as the grande.. see the GUIDES ;)

INITIALLY: you need a 12 volt supply..

That will run the fan ( the resistor is just reducing power for slower fan speeds)
