The wife's car doing the same I've replaced the plug which goes into the resistor and we still had no joy. So I have just try a new resistor all working. Now probably a really stupid question but the green part is it supposed to get that hot? Also there were smoke coming from the brand new one. Any help

Re: Burnt wiring in heater

The way they engineered this is realy bad, a PWM drive would have been better, but more expensive.

All the power that is not used to run the blower is simply lost in heat by the résistors, so yes, it can become very hot, specially if you keep it running at low speed since more curent is dissipated in the block. On 4th position the résistors are all by-passed.

Regarding the smoke, I wouldn't worry too much IF it stopped after a little while, new stuff may have some greasy packing stuff / finger prints etc. on them. However it's worth to double chek the plug is firmly inserted to avoid extra heat ...

BRs, Bernie

Re: Burnt wiring in heater


Also note that the resistor (green part) is normally cooled by the airflow from the fan. If you test it outside the duct were it normally fits it will be a lot hotter than normal.

Re: Burnt wiring in heater

Hello,


I'm sorry for bringing up this old post again, but I'm having the same issue - it seems as though my fan has died - it was working intermittently and then all of a sudden today has totally stopped working. I've taken the clip off from the resistor thinggy and its melted one of the pins so I'm going to buy this repair thinggy off ebay.


My question is, its almost as cheap to buy a new resistor pack too (with the wire) but before I buy anything, I just wanted to check and make sure I'm buying the right thing as, of course I'm searching for a corsa part. Will the corsa resistor pack thing work fine if I buy both the connector and the resistor together?


They look identical to the fiat resistor packs, so I'm just wondering if it was safe to use that?


Thanks for any help.
