Hi, hoping someone might be able to point me in the right direction of a problem that's starting to drive me nuts:
Hi, hoping someone might be able to point me in the right direction. On the wife's MK3 Leon (2016 1.6tdi with stop/start) had a load of odd electrical issues recently. link deleted [moderator] Firstly 12v socket and blower motor stopped working.
Was working fine, stopped next journey, worked again then died permanently Took the blower motor out, works fine with 12v direct to the fan. Fuse had blown on the 12v socket so replaced that - may have been related or may have been one of the kids plugging in their dvd player. Thought it might be the controller/resistor pack, swapped for an apparently known good 2/h one still nowt. No codes on vcds
Checked all fuses in both fuse boxes - behind glovebox and in engine bay. Few days later on a long 4 hour trip I dropped the e/window and the traction control/abs/headlight range warning lights all came on. plus odd ball stuff like winter tyres and cornering light errors (which it doesn't have). My cousins garage up north read loads of low voltage warnings and rear left abs error. He swapped the abs sensor, checked wiring back to abs pump and all ok so he thought it might be the pump.
Still suspecting electrics as more random warnings on on the way back I put a new battery on it and all warning lights went away. Blower still not working though Fast-forward a couple of weeks and the mrs driving it yesterday, put the rear wiper on, which didn't activate straight away, but when it did all the warning lights came back on again.
I found this thread on another forum which said blower motor, 12v socket and rear wiper shared a circuit which makes me wonder if it's a faulty relay. However, the thread was for the mk2 model and theres no 373 relay on this car. On the advice of a mate who's good with this stuff, left ignition on, plugged a phone charger into 12v socket and removed each relay in those 2 locations 1 by 1, hoping this would i/d the one for the blower/rear wiper/12v socket circuit. However, power to the socket stayed on the whole time so assuming there's no relay. Ran vcds again - No obvious damp issues (stopped working in the middle of the recent 6 week dry spell). At a bit of a loss now apart from start checking every bit of wiring on the car for damage.
Car drives spot on.
Latest vcds scan below with the non-fault bits removed
Any ideas would be greatly appreciated, Thanks
