Electrical problems

Post by thecolourpurple »

So guys I'm having a major problem that is proving to be a right pain in the A*** to resolve.
Going back a few weeks I reported my blower had stopped working & found out that reverse lights/reverse sensors & main beam wont 'lock' in fwd position on the stalk. Had 2 auto sparks look at it & both said BCM has fault. Bought new unit from VW & had it coded. Guess what still got same problems. It's been at repair shop for 4 weeks now & everyone involved is scratching there heads & we're no further on

I think your facing three different problems here.

The blower fan is quite a basic control, there is a fused supply to behind the passenger side storage box, from there it's a four step resistor or electronic control. First step would be to check for voltage (0v and 12v) at the block behind the storage box.

The reverse signal, if you have manual comes from a simple switch on the gearbox. On DSG this is a switch inside the gearbox.

The high beam not latching forward is a mechanical failure inside the stalk and will require a replacement.

Hi
The ignition voltage to the relay has been lost.The blower works perfectly when the supply is bridged from another position.

I have this exact problem

No heater blower

No reverse light

No main beam on the forward push of the stalk

The flasher works pulling switch back.

I had same reply telling me it’s a BCM problem but I reckon it’s simpler than that

I would be forever in your debt for an answer

My blower was the same but it did work on setting number 4 sometimes. So may not be the same issue. But for £11 maybe worth a try.
I swapped out the fan resistor
Part number. 1K0959263A
I actually got it on Amazon! Was the cheapest and quickest £10.97.
TPS wanted £35

This fixed my fan strait away.
It’s easy to swap on my touran dash it’s below the glovebox.
Caddy same area.


Depending on where you are based?
But if you are close / prepared to travel to Sheffield there is a wizard called Chris Bellman he’s online only and you can find him on Facebook. Just look for Bellman, auto electronics in Sheffield.
He is an absolute genius with electronics.

It might be a simple problem but one thing I can tell you, Chris will 100% be able to find it and resolve it.

You may just want to keep trying different things and get guidance from this. Very very knowledgeable bunch of guys on here. Or if you’re like me, you may want to just drive it to somebody and be done with the troubleshooting! If so, Chris is your man
He only works on the vag group vehicles and is very well known in the industry. Supplies, installs and codes most peoples MK4 rear lights. And multifunction steering wheels, along with, and 3-D clusters install, coded and mileage set.
In his words I’m not on auto electrician I specialise in auto electronics.
I am quite confident if you ping him a message on Facebook with your problem, he would be able to fix it. He does not have a phone number that is quick to respond to Facebook messages.
