I'm having trouble with indicators and central locking in my 2018 Mitsubishi Pajero. I've checked the fuses and they are all good.
If it was just the indicators or just the central locking, you could spend a long time figuring this out. But if both the indicators and the central locking went on the blink at the same time, any mechanic's suspicions would be drawn to the body computer. This is an ECU that controls all those functions, including cruise-control, heating and ventilation and much, much more.
If the computer unit fails or starts to behave erratically, you'll notice these functions either working intermittently or not working at all. In some cases, a new body computer will be needed, but you can try this trick at home. Disconnect the battery and leave the car overnight. You may find when you reconnect the battery, all the functions have been restored.
The other trick to try is to hold the lock button on your key fob for a minimum of 60 seconds. That, too, can often reset the body computer and reboot thigs back to where they should be. Failing that, it's off to an auto electrician.
