Door lock assembly- rh

[TimR]

I've been looking for a door lock assembly since mine decided it only works occasionally; a scenario I expect only to grow worse..
I wonder of anyone has a defunct unit (either side) that they have removed to fix their own issues. These were still available only 18 months ago at about £80-100 (incl tax) but are now NLA. None of the reputable breakers have anything...
If anyone still has a junk assembly they could donate, I want to see if they can be opened and repaired effectively, I would be grateful...!
Perhaps this has already been attempted..? I dont know.
Left or right, it doesnt matter at this point really !

Thnx 4 reading

I think mine is playing up aswell, but I knew this when I bought the car. Hopefully they can be repaired.

My passenger lock solenoid has died. (2003 4200 coupe). Not available through suppliers. So if anyone has kit, or can suggest a source or has any suggestion, I'd be very grateful. Currently I am manually locking the car at the passenger door, and setting the alarm using the fob. But every now and then the synchronising seems to have a hiccough, and the alarm goes off hours later. Hence no alarm set when in my own garage. I might pluck up the courage some day and try and clean/adjust/repair the solenoid, but that is a final step, rather find a replacement solenoid.

Sounds familiar. If you have any luck, please keep us updated.

I remember its the same part as the Lancia Kappa, not that it helps since its effectively just as rare.

 

[PeterMonk]

Ta. I half hoped someone might point me to a common Fiat part.

Pull the fuse; it's the way of the world.

That does sound all too familiar. Im not at all certain that the assembly can be opened to access a repair. I havent removed mine to see because of the ongoing issue of not being able to secure the car as a result.
My car has woken up from the winter's standing up with a plethora of puzzling and random electrical issues this year. Odometer, (requiring a replacement binnacle) An HVAC that reverts to MAX everytime a button or dial is moved. The door lock assembly on the blink, and after 800-1K faultless miles on PMR8A plugs last year following replacement, Ive had to replace them with PMR8Bs because it was so reluctant on cold start with the single platinum plug...Oh, and a dash bulb failure warning when pressing the brake pedal but ony when the lighrrs are on..! Got to love 'em !
Back to the door lock solenoids, I'm guessing it might be a case of cutting one open for access. Establish if it can be repaired by design, and figuring out a way to plastic weld(?) the casing shut after...?
Ill try and find the thread. It was about 18-20 months ago but a few members had bought new and maybe have used/defunct units kicking around..
@2b1ask1 , @todd.the.submariner (from memory)...Sorry to stalk you guys over the net. Not good etiquette Im sure. I might just be barking up the wrong trees, so sorry about that...! Desperate times....

I am cautious about trying to "mend" the solenoid because I can remain indefinitely safe and secure as it is. I'm not a mechanic, just enjoy having an otherwise perfect mechanical beast and want to keep it so Over the past year or so I've rectified several (non trivial) problems, so this is an annoying, small thing, and I don't want to make it worse. So I'm exploring every path before taking a possibly irreversible step

You might explore an auto electrician to test the mechanism and the solenoid. There may even be a generic solenoid at such a place - Maserati doesn't make solenoids. So it has to be a supplier that makes the solenoid and an auto electrician might know who makes it and where to get hold of one.

SportsItalia changed both my door lock internals for OEM ones I supplied. It turned out however to be one of the ECU units that had Failed - Door Module, old water damage somehow!

 

[MaserMM]

The marked opening is a fixing point for the assembly. The clam shell is riveted from the other side through this opening. The edges of the clam shell are easy enough to prise open. The riveted post also acts as a mount for an internal cover plate over the lock drive motor. Which doesn't have any identification markings but is almost identical to this



Which is available on eBay for a few quid. Maybe the rivet could be drilled and refitted? Would a bolt and plenty of thread lock last?

 

[PeterMonk]

Thanks, I'm in touch with a reputable local auto electrician, and he's got it on his list to try and find an alternative solenoid if the OEM is no longer available. He's enthusiastic but not very optimistic - hence I'm enquiring everywhere I might get lucky.

 

[HTAFC4200]

Good luck, if he's able to solve the issue, he may well have a bit of business coming his way!

 

[TimR]

All good info- thnx. Maybe need to find an Indy if we're in with the chance of finding a disposable trial unit..? I was quoted £420 for NOS out of Italy only weeks ago. Bit rich for my blood. Although a certain amount of " feck off" crept into my rash decision making perhaps ± ! In my defence, with them being so hard to find, and dwindling, I believe a refurb may be our best chance, longer term.

 

[HTAFC4200]

When I took my car into Shiltech and I mentioned the door locks etc the response was "I believe they're French electrics."

I replied

"Oh no."

If only I'd known before buying lol

My problem is a non-responsive solenoid, but this is "integrated" into the lock mechanism.

I've had quite a (non) productive day. I expect others on this string know everything already, but let me share my understanding of the components situation. I've been in dialogue both on the phone and e-mail with several people in the UK and on the continent.

The door lock mechanism that I need, including the solenoid, is part number 67294900. The OEM stock across Europe ran dry a while back, and all demands can only be met by luckily finding a used part, such as from a scrapped vehicle. One contact, a specialist in fully refurbishing classic Italian GTs, indicated he knows the absent door lock mechanism well, it is on his list of no-longer-available components (he mentioned an identical shortage of suspension kit). A serious enough matter that he has been seeking an engineering firm to run a temporary production line. (It becomes a dry market in the £250K refurbs if the buyer knows that when the door lock goes his investment becomes questionable).

It looks to me that the unavailable unit is listed at about £60 - £70, but I wonder if any short run new locking mechanisms would be priced at less than £600 - £700?

I have concluded that, unless another poor 3200/4200 owner loses control at the end of my drive, such that I could strip his crumpled vehicle before calling for the ambulance, I will not be seeing the part I need. The mechanics of my lock seem to be in fine order, it is only the non-responsive solenoid. So I've already been in touch with the auto electrician to plan to get the unit out and see if the wiring, connections, and contacts can be freshened up enough to create a more wholesome bit of kit, without b........ it up and stopping the mechanical movement working.

I'd be so pleased if anyone's got a bit of good news on this.

...the alarm still works even when the locks don't...so there's that!

 

[cheshiremaserati]

Seems the auto electrician is your best bet. After that, it looks like finding the door lock mechanism from a scrap car or breaker.

 

[PeterMonk]

Yes, with luck this will turn into a non-event after he poke around inside.
And yes, in the meantime it's still great to purr around in, it's not really very difficult to pop round to the other side to lock it
