I started my car this morning and I have 2 malfunctions.
1. Right tail light not working
2. Right tail light not working, substitute light is on.

I guess both messages mean that my right tail light is burnt.
I never changed the tail light before. Is this easy to change?

 

Yea, it's not the light that you change. It's the bulbs.

 

How do I get to the bulb? From the outside or from the trunk?

 

Trunk. Pull the carpet back and you'll be able to access the bulb sockets.

 

Did not drive the car on Sunday and when I drove the car this morning, the Malfunction was gone. I resrarted the car and still no Malfunction.

Guess I don't have to rush to the dealership. I will still change them (both of them) next time I go.
