ls430 drivers door switches not working, fuel cap door won't open, remote central locking not working, automatic lights won't come on, interior lights not working, any ideas

 

Is this a recent problem? Did all of these issues come up at the same time on your car, or was it one after another?

Start simple. Check all of your fuses for breaks, as a few might be blown

If any are blown, it could have been caused by wiring issues

 

Check fuses

 

its my father in laws car and its a RHD, the car is in sain and it was left for 5 weeks and the battery went flat so he go it jump started , checked all fuses and all ok, now the only thing working on the drivers door is the window , all the other windows work from their individual switches, and now the fuel cap door won't open

 

If all you did was jump start the car to get it running, you need to invest in a new battery as the existing battery is likely suspect. The other checks for fuses are still valid.

 

sorry forgot to mention, new battery has been fitted also

 

If it's not the fuses, try disconnecting the negative terminal from the battery, wait for 15 mins, then reconnect the negative with a firm shove.
Sometimes if someone dithers when fitting the negative terminal you end up connecting and disconnecting several times and that can cause the electronics to get into a confused state.
The 15 mins lets all of the computers fully power off, and the single reconnect powers them all up at once.

 

Did it get jump started the wrong way only reason the car would just start having electrical issues after sitting amd being jump started.
