Disconnecting The Aux Heater

[Ryanon]

Hello Everyone, fantastic site here and some very knowledgeable people who I am at the mercy of tonight

I have read read read all day about my smoking Aux Heater, and forced to seek help through absolute embarrassment lately as whenever I drive somewhere, People think my car is on fire I understand this may be the plug needing replaced, and we are in the snow here in Scotland now so can not do anything for the time being. I need to use the car and really have to stop this smoke just now.

Can someone tell me which fuse would shut down the unit just now so I can coldly go about my business till I get around to having it sorted properly? I can not seem to find an answer anywhere for this.

Any help would be greatly appreciated.

Massive thanks in advance!

have you got an ECON button next to your heater controls? This should disable aux heater in winter and ac in summer

Hi Rob, thank you for the reply! I do not have an ECON button

I don't think there is a fuse for the Aux heater itself. I'm pretty sure it's powered by the fuses for the aircon system, so if you pulled the fuses you wouldn't have any heating at all.
I know it means crawling under the car in the snow, but perhaps you could just disconnect the electrical connector from the Aux heaters fuel pump. I'm sure it's mounted around the fuel tank somewhere. If it's not getting any fuel it wont create any smoke.

Thank you Jim! I will just need to brave the cold and see what I can do! Much appreciated!

An Update:

By not requesting instant heat inside, I managed to reduce the amount of smoke this morning, only sparsely doing such when I stopped. It's very temperamental, only wishing to embarrass me when folk are around Hahaha

So checked the fuses, found the heater is in fact fuse 12 which is also for the AC - my AC unit does not work and was disconnected when I bought the car - so I pulled the fuse and monitored the driving and inside conditions. The Aux Heater does not fire on now, no smoke, and the car heats up as should as normal cars do. It sits perfectly at 90c (half way) and varies down to about 75 ish when I request full heat on full blower. Obviously, I reckon you could not use the back heaters and have the car sweltering hot with the AUX disabled, I also think it will take a wee bit longer to get the car up to it's temperature for optimal driving. It does drive perfectly fine though.

Must do job before next winter, but in the time being, I can drive without the stress of the last few days.

Thank you everyone, greatly appreciated and I hope this helps someone with similar problems .
