I hate electrics,
Can anyone give me a pointer on solving or at least temporary bypass so air suspension will level.

My right hand front door lock is not working but does not give problems with door open messages etc. Motor I believe is goosed.

I know tear is earthed through the same front lock.

Help please :)

It gets it's ground through the RH front door latch but all that means is if the front door is locked it has no ground so can't be opened. If it is unlocked then the ground will be there and it will work. Presumably you can open and close it properly? If you can then it is likely the switch in the latch in the lower tailgate is either broke or the latch itself has worked loose so it isn't closing fully.

So a microswitch in tailgate maybe iffy or latch.
At least I know where to look
