Auris - Clearing drainage holes/pathways

Hoping for an education on where and how to clear all of the rain/water drainage holes on my Auris mk1.

Over time they get blocked/dirty & need to be cleared.

Need guidance in where they all are & how to do it competently.

Many thanks,

Kojac.

Rear lights , needs to be removed from the car, thoroughly cleaned, use new gaskets or silicone seal and put back on the car. On the front when raining and you inside the car should hear water flow through the body somewhere around windscreen passenger side, if you don’t hear that you will need to investigate further, possible removing of plastic surround windscreen and wiper arms. I haven’t had any issues so far on the front, only rear. 

I had to replace the driver side front wheel arch liner on my car. When i took the old one out, it was packed with fine silt caused by decaying leaves. Luckily no rust into cills.

There is a horizontal drainage path under driver door , a frame cill area. Ensure you keep that clean.

Worth taking all the liners and covers off every couple of years and cleaning out. There's lots of dirt traps, you can prevent / catch any rust before it gets serious
