Power Sliding Doors Dead

[Rich44]

Hi all

 

When trying to open both doors on remote or button nothing happens. I've metered out the door wiring for faults & each wire has continuity does anyone have further suggestions? I've checked fuses too.

 

If the door is closed softly to motor operates the door catch & pulls the door shut.

 

The pull down TV is dead too but the dvd player plays the disc as you can hear the movie I'm guessing the doors & screen aren't related.

So they open close via the buttons inside the car?

[Rich44]

They open & close manually only, the soft close part still works if you close the door to the point the latch engages it then pulls the door closed on the latch.

 

The door motor itself does nothing at all. I've had the meter out and check continuity from the multi plug to the point the cabling disappears into conduit in the door pillar.

 

So I'm thinking either some kind of controller failure further up the chain however these work, a break in the cable inside the sliding door or the motors have failed completely.

 

What's the next most likely if the cable in the plastic snake appears ok?

[QinteQ]

NEG battery terminal off 16 minutes will reset the BCM and the IPM which distributes power to the doors when the BCM instructs them to open / close. If that does not help back to the door chain which can be intermittent and usually makes / breaks according to the stress point of the curve. Lot's of vids on YouTube. Best of luck.

I'm thinking if it was a cable failure then only one door would not work and not both

[Rich44]

Yeah I thought that bit I was then thinking what if it's separate faults on each door they could've occurred over time and not been repaired.

 

I'll have another crack Monday/Tuesday. I didn't know if it was related to the other thing on the floor there with a 2 pin plug off the same wiring loom, I'm guessing some kind of sensor.

[bignev]

Aha. Just twigged you've presumably just bought the 2.8 2006 that was on another post recently?

 

So I guess the doors didn't work when you picked it up? Which of course agrees with your comment that they may have both broken over time.

One door on ours would motor open or closed until it flexed the cable to the crucial point then stop, so it could be when you are metering it out the cable is making a connection as it's broken inside but of course the insulation is holding it together.

 

And do the central locking motor latches still work?

 

Do check the little button on the overhead switch bank, it turns the doors and tailgate off.

 

The two pin plug / sensor is a crash sensor, added on the facelift models. I've just tried mine unplugged and the doors still motor open.

 

On the DVD, I have to press the headset picture on the remote control to put the screen on each time it's started.

[Rich44]

Ok I've double checked both cables and cannot find a break anywhere. I've pulled the trim off and checked everything & all looks OK.

 

Odd thing tho if front passenger door is locked when you double click the remote to operate power door on nearside it unlocks the passenger door but does NOTHING else.

 

If you press the door button on the pillar nothing happens no matter whether the door is open or closed or anywhere between. Anyone got any thoughts on this? I've tried disconnecting the battery as above but behaviour remains the same.

 

DVD screen doesn't respond to the buttons on the ceiling BUT pulled the remote apart and the circuit board is snapped so hopefully that answers that one, just need to find a replacement now unless someone on here wants to program up a learning remote for some pennies?

 

No car isn't 2006 from on here it's a 2005 bought from a private seller on Facebook, lots of history recent cambelt etc everything important works perfectly just the dvd player & sliding doors and I'm fussy so want to try getting them working

Duplicate post sorry Edited April 18, 2017 by Rich44

Small consolation, but it is supposed to unlock the sliding and front doors of the side you want to open, so that's normal.

 

The door pillar button doesn't unlock the lock, so that's normal too.

 

On the wiring, did you do a resistance check as well as continuity? 1 strand of wire would give a reading, but I'm not sure if it would carry enough voltage to actuate the motor.

 

I am guessing on this but the closing finish motor may be fed on another wire.

[Rich44]

Ahhh ok well that helps so at least that's normal behaviour.

 

Yes having looked at the wiring the door latch motor is fed from wiring internal to the door. There's a control unit in there the wiring loom from the door goes to that then back to the main door close motor & splits off the The door interlock.

 

I'm thinking I might pickup a known good loom & motor just so I've got some good spares to swap around to try & help the diagnosis.

 

At least it's fairly simple system.

 

I think what I'll do tomorrow is some proper checks as you suggest resistance and also stick the meter on & look for power being applied, maybe I can start with the socket in the door pillar then work along from there.

 

I'll get there in the end I'm sure, thanks for the tips they all really help. Loving the car already though. I've even got the wife insured as a learner on it pmsl.

[Semmysonic]

Does the tailgate work as it should?

[Rich44]

Yup tailgate works perfectly just the side doors that don't.

 

Been out there again all wires read within 0.1 ohms of each other. Starting to wonder if someone's fiddled with the wiring somewhere and mangled it. Once I've got a few pennies I'll get a motor and try swapping that around as at the moment really that's looking like the last piece of the puzzle or possibly the control unit in the door.

 

It's a shame there's not a wiring diagram somewhere so it'd be easy to look for trigger wires etc

[Semmysonic]

There is workshop manuals floating about on here, take a look in the thread about huge battery drain

[bignev]

Ruddy hell the Mrs is a learner in one of these! Brave woman.

 

My wife loves ours, but she's been driving for rather a long time! And had some swift or big motors over the years.

[Rich44]

Well she's supposed to be learning in the Seat Arosa but sometimes it's just not practical as too small.

 

Like tonight, it's youth club 3 villages over then whilst kids are there we go food shopping so she drove tonight in it for the first time. Country lanes 30 then 60mph drop the kids off then few more country lanes then onto busy A road.

 

I was impressed she did really well.

 

She was learning before we had kids about 15 years ago but some lunatic biker destroyed the car she was learning in, luckily I was driving and it was during rush hour so everyone stopped as witnesses & the biker got prosecuted on about 5 different things but that put her off, now we live in rural Norfolk tho & I'm now disabled so she needs to drive to get herself about.

 

Little Seat Arosa is a cracking car paid £395 for that 1.4 auto, 56,000 miles, fsh etc and it's just gone thru the 2nd mot needing nothing doing, straight thru not even an advisory not bad for a 1997 car!!

 

Hoping the Grand Voyager will be just as good. I really love it already

[Semmysonic]

My wife won't even contemplate driving ours, can't blame her though, we live near Birmingham and it can get a little interesting squeezing it through rush hour traffic

[Rich44]

Lol we live in rural Norfolk & it's pretty hair raising when you're driving & come across an idiot in the middle of the road.

 

I won't go out without a dashcam now.

 

It's a nightmare when the tourists are here, take away the white line on a road & they're incapable of staying left
