Good place to start by the sounds of things, don't forget to register it when you get round to fitting.
Next on my list to remove, I’ve got new door contacts to fit for the short circuit I will update you on what happens
Change the battery first and check, I take it your confident enough to swap the locks out, easy enough to do although drivers side a bit of a fiddle with lock barrel being aligned. :thumbsup:

need to read your post again and look at what needs to be done and what to use to reseal the inner door cover. Fairly confident on taking bits apart it’s the putting back that can be tricky

Door membrane should seal back up as is unless you've ripped it into ribbons. Taping if would be fine, this membrane should not directly be stopping moisture getting in the car, if it's getting wet you have other problems, any water getting in the door seal should naturally run down the door skin and drain out the bottom of the door.

Actuator is only 3 screws holding it in position, unclipping the inner handle Bowden cable is easy, the exterior handle one is best removed when the actuator is moved to the cavity opening in the door. The door button just unclips as does the power.

Drivers side the same but take note how the lock barrel fits, only a wiggle to get it back in through, from memory I think there is a screw holding the barrel on position in line with the lock above the catch. Think there is a grommet hiding it, only loosen though. This can be a bit fiddly but you'll know when it's correct.

Make notes and take pictures for points of reference like the route of the Bowden cable on the back of the door card :thumbsup:

I wouldn't do any of that though without first fitting the new battery, registering and testing. It's only tiny fluctuations of voltage that can cause these issues and having 2 off actuators failing at the same time is beyond unlucky.

Hope that helps, anything else let me know

Sorry for the delay, had some family emergencies so everything got parked.

so battery was the issue which now changed but that caused a whole load of other issues with engine no started, locked steering and locked handbrake.

got the steering lock fixed and now working on other faults since battery died :-(

thanks for the tips, hopefully get this issue fixed and will keep the post updated

Yep - failing battery casues all kinds of madness across unrelated electronics in the car.

If you have more than 1 issue that seems like it needs intense diagnostics - always start with the battery.

These have a pretty short life, 5 years old batteries or older will always be a prime suspect if chasing electrical gremlins.

Consider it a consumable.

No need to remove handle just the lock barrel
It's held in with a screw hidden behind a rubber grommet in the door opening.

Take note how it fits together, a bit more fiddley than passenger side.

I thought the replacement battery sorted your issues?

Have you scanned the ECU's, in particular the FRM?

If the battery was the root cause of all the issues I would've expected a replacement and resetting via OBD would cure the locking issue? Maybe resetting winows also?

Battery has been changed, had a variety of issues afterwards locked steering wheel.

Currently have the 9cbc (not rechecked) since yesterday and now warnings in the aux
sensor.

All modules scanned with ista d and responding, need
To rescan and maybe reset frm again to see if any changes.

Thought the short circuit would be the door locks but nothing changed after installing new ones.

Looked at various window reset posts, which one do you use/recommend

Trust you replaced battery with OEM spec AGM 70amp 770CCA?

The window motor has a hall sensor to detect positioning, either manually set using window buttons by holding down at bottom for 20 secs or so and repeat at top position.

Ista d will also have a reset function within the FRM scan I would suggest. I use INPA and that does it.

:cry:

Sounds like a nightmare.

Potentially the window motor could be your next thing to consider at a relatively low cost and a potential source for a short.
