indicators

Hi guys I have a Clio 3 and I've been trying to get my side repeater lights to work. The previous bulbs were left in there and 1 of the sides didn't even have a cover. In the images it shows the remnants of one of the bulbs and as you can see it's heavily corroded. I got some 12v replacement...

Really need some help please! Have some electrical issues that i'm struggling to diagnose as i'm brand new to these cars. - Passenger window - doesn't go up or down... I've replaced the switches both sides as i've heard this is a common issue. Before I did this, I did manage to get it to go up...
