1994 Vogue SE "Soft Dash" Power Seats/Mirrors issues

[colwedd]

Hello, owned this vehicle for 10 years now and love it but electrics are giving me the ****s! Currently whenever I attempt to move the driver's seat in any direction the drivers mirror moves but not the seat... is now a major issue as someone got it and the seat moved to almost fully reclined position... not good to drive this way unless you be gangster! I am assuming it is some sort of control issue with one of the computers that I have read about in various threads here. Have downloaded so many emanuals all promising to give detailed explanations and directions... not many of either in the RAVE that I have seen and the electrical wiring diagram requires some prior knowledge of wire colours etc. and maybe a masters degree in following lines on a page.

Anyone got any ideas? Got the seat out, which was a bit of a drama due its position. But looking at all that stuff without a map is daunting at best.

HELP!![bawl]

G`day ,

most likely the battery in the seat ECU has leaked onto the circuit board which will cause the problem you describe .

The seat usually needs to come out so your part way there .

Do a search for RRC Electric seat ECU / battery /circuit board and you will find explanations of what the problem is and how to repair .

I knew the poms were a bit dodgy when it came to electrics but seriously that is just ****ed up... all they had to do is turn the thing upside down and the only damage is a flat battery... which would mean they don't work!

Cheers and thanks for your reply, even though I posted in the wrong place

Ooo Yeah...the Battery Saga. Been there-Done that !

Bought a larger capacity battery on evilBay (some years ago) and painstakingly fitted same. Begorrah! - Everything worked ! - Must be the Luck of the Irish, t' be sure !

If you can track back my posts on the subject, there's a few pretty pictures of the PCB etc.

The other half of the equation is... the seat switches. They can be a 'Consumable Item' at worst. Leave them till last, as cleaning & re-furbishing them sometimes ends in tears.

You worst nightmare is the gunk has leaked AND eaten gaps in the tracks. Patience, bits of wire, a steady hand on a good soldering iron and you MIGHT be lucky. - Assuming none of the integrated Circuit chips have been damaged...

When it works as it should it's very very good... but when not, it's horrid.

I started going down the path of repair with my 95 RRC, but then elected to convert the mirrors to just electric a la D2, and likewise the seats as stand alone electric, both without retaining a memory function.
If you proceed and find problems, I may have some working bits amongst my never throw out collection that you are welcome to play with.

The silly thing is... the system is more German than Pommy. - For example, those seat-switch modules are used in some MB cars, however they're mounted up on the door card, out of harm's way. Rover stuck them on the seat squab as an afterthought... where they can be damaged and dusted.

If you're feeling Brave, consider Gavin's suggestion and you could use press-buttons and make up your own seatswitch-panel and use them to drive the myriad of relays on the ECU circuit board.

Operating the MIRROR controls and getting a reaction from the SEATS.... sort of gives it away that your PCB may well be ..... "Cactus" (Highly Technical Term meaning stufffed )

I'd be inclined .... to revert to MANUAL operated seats. After all, how often do you NEED to adjust a seat ?

Every other electric seat I've used - Statesman, Ssyangyong, Magna and MB has been vastly superior to the RR's, smooooother, quiet, effective and quicker so I don't think they're worthy of restoration !

Hi All,

Very interesting thread.

I too have a problem with my 92 Classic electric seats ....mainly they don't work.

Missing the switches on the seats will do that ... and I've search everywhere (24 months) and can not find replacements.

On wreaked vehicles they are the first thing to go ....I pulled out the worm drives and used a cordless drill to position seats in correct position.

I purchased a year ago a set of manual seats same pattern but in the cream leather rather than the dark brown of my interior.

Haven't fitted them as I don't relish the difference in colour although I know a set of seat covers will go a long way to fixing that problem.

Will need to look at Gavin's remedy of using D2 electrics for mirrors.

There's too much electrics in the 92 .....love my 81 for its simplicity ...three fuses and wind up windows .... although the 92 does ride so much quieter and nicer ...

That being said she has been reliable ...although I could have just put the mockers on that.

When all said and done I do love my classics :)

The knackered circuit board and the interconnect with the mirrors were too much for my peanut sized brain to fix on the LSE as the switches were also in pieces.
my solution was 4 small chrome toggle switches mounted in the top of existing seat switch pod beside the seat base where it was from the factory. Directly wired to the 4 motors under the seat ( no ecu or circuit board ), solved needless complexity at 20 years of age. Quiet and quick as any other seat I’ve used, I find it comfortable as had upholsterer mate renew foam and hide.
Just returned from 2000km trip towing 2500kg and no discomfort at all . Slowish trip as mine is 300 tdi powered, least it was relatively frugal on fuel for an old bus.
Must investigate repowering the mirrors.

Hi Justin. Any chance of a pic of your seat controls?
I have converted to the stand alone D2 control switch for mirrors and very happy with the system. Apparently you need the D2 switch with the extra connection to make it all work, albeit with no memory!
Cheers Gavin
