VW Sharan 05 plate 2.0TDi Electrical problems

[TBaxie]

Hi there,

As I did not see a specific Sharan section, I thought it would be best to post here, apologize if I put it in the wrong place.

As the title says, I have a VW Sharan 05 plate with a 2.0 TDi Engine.

The car has been suffering weird minor issues, which is started to grow larger and more constant and unsure what could be causing it.

Inital faults with other problems going down wards

Electric Window switches wouldnt work correctly (Drivers side) this got replaced and problems went away.

Now, on and off, no way to judge when it will happen, the drivers door will come down but wont go back up, after turn off's and waiting, it eventually works again.

Similar with the passanger side, sometimes it will go down but not up, this is with either driver/passanger trying to close it.

Then lately, when I try and open a window, if it doesnt want it, the harzards now flash if I touch the window switch

I also have a problem with my Central locking, where some doors wont lock, it can be random, it can be drivers door, door behind drivers and all werid combinations. I note my flip key thob no longer seems to open/close doors at all even with battery replaced.

Spare key which isnt a flip key works but as mentioned, sometimes not all doors lock (same with manually locking door, not all doors lock)

The latest thing is, when I put the rear window heat switch on, the hazards will come on but at this stage I hear a clicking as well to the hazards.

One that hasnt happened recently was a few weeks back, driving home at night, my hazards kept coming on without being put on randomly.

I have checked what fuses I think are linked to electrics and have no problems, that said, few christmas's back my wipers stopped and it turned out a fues with a symbol I didnt think related to wipers was the problem, so would be grateful if that could be mentioned

Any help would be amazing and getting alittle worried that this is going to be a huge bill if I put it into a garage

hey
having just solved many electrical problems on my 2002 sharan id start by pulling back the rubbers that "protect" the wires between the body and the door.
these have a habbit of nipping at the wires then eventually breaking and sometimes shorting them.
with the locks being conected to the hazzards (for the alarm arming/disarming) this could be your problem, not sure why it would be conected to the heated rear window ?
id have to check related fuse's.
but there you go give that a try.

The heated rear window connection is probably that the heated door mirrors are activated when the HRW is switched on so there must be a feed to tell the mirrors to heat - fix the wires in the convoluted trunking and I'm pretty sure problems will vanish

Many thanks for the reply guys,
Am going to try google up how the best/easiest way to get this trunking off, cause there doesnt seem to be much room for play.

If there is any tips/tricks to it, I would be greatful to hear, will be nice to cure these problems without the silly garage costs

Thanks again.

where it go's into the body, this is a screw conection just use some force and turn it anti clockwise this will disconect it from the body, then the rubber pulls away from the plastic and you can kind of push it into the door to reveal the wires, its pretty easy

Many thanks for the advise, it seems after I got the plug out of the side of the body, I had the large brown wire completely shredded in half. plus a few other wires with damage.

Had to go out buy a soldering iron and do a "extending" job, once done, all seems so far as good

Cheers for the help!
