Fan & Lights Gremlin?

[domino]

So, here's a feature I haven't found in the handbook - perhaps someone can shed some light (badumtish).

Was just out in the car and, as it's freezing, put the blowers on full (manually) to heat up my feet. Happened to then notice that the interior lights came on..? If you drop the fan down by one notch, they go out. Back up 1 notch to full blast and they come back on.

What voodoo is this?

don't know about p38 and it's electricery but i'd say that is usually an earth fault.

As above....!!

Would it be a bad earth relating to the lights or the HEVAC?

Take a look at the earthing arrangements in RAVE....you may find they share the same earth stud!

Hmm, I wonder if the radio also shares it.. as that's developed a noticeable whine while playing cassettes and CD's - only started after I removed some of it to sort the o rings.

hmmm...

I'll still need to check but thought I'd mention the problem isn't there anymore!

Damp causing earth issues??

Just to come back to this and update slightly - it hasn't happened again since that one time however I have noticed that I've been getting problems with the tailgate. When driving over bumps or the traditionally great-condition roads, a warning flashes up that the tailgate is open and the lights come on.

I presume there's a switch/sensor in the tailgate area that might need some TLC. Don't fancy going out in this weather to look for it, mind.

Yes if it thinks a door is ajar it will put the interiors on. So maybe coincidental to the heater fans and a duff switch on the tailgate. I can see no relationship heater fans to interior lamps on diagrams with a quick look.

Just need to hope it behaves itself - MOT tomorrow afternoon!
