Morning. Noticed yesterday evening my passenger side wing mirror puddle light isn't working.  Driver side fine. Are these easy to replace? Looks like it's led. Thanks.

You could pop it out and see if it looks like water went in or something of the kind. In any case they are replaceable, and upgreadable also!

How do you get them out? I can't see a way from outside so I assume I have to take the mirror out and the casing apart. 

Managed to get the light out. I'm a bit thick when it comes to this. How do I test wether it's the light or the wiring to it? I do have a multimeter not that I really understand it. 

Must admit I don’t know how to use a multimeter nor have one 😞 

 

I’m sure there’s plenty of videos online but if getting the light out wasn’t too hard, get the working one out and swap around, if the fault follows then it’s the light 

It's ok I think I figured that watching a few videos. So I tested the wiring which seems to have voltage and I tested the light which seems to have resistance so I'm happy it's the light that's at fault. 

 

For the wiring I set the multimeter to DC volts put the red cable on the meter to the red wire on the plug and the black to an earth in the engine bay and got just under 12v

 

For the light I set it to ohms and put a terminal on each terminal of the light and it said 1 which on my meter means there is resistance. 

 

Now what I have cocked up on is what way round the 2 wires go. Both fit on both terminals!!! Can't even find out what they are for. 

Took the other mirror off. It's black blue on top so had them the wrong way round!!!

Those cables for heated mirror

Sorry I mistook this for the door puddle, on the bottom of the door card. Sorry for the confusion!
