My DS5's front left turn indicator stopped working, seems to have a lot of moisture inside. Funny thing is, when it's cold outside, below freezing point the indicator suddenly works

To dry it, I tried to pop it out pulling out the small black lid in the corner below the indicator to unscrew the torx screw. But once the screw is removed I am still unable to take out the indicator assembly and cannot figure what else has to be done. Any help from you guys? If the VIN is needed, it's VF7**************[VIN obfuscated, can be read by forum staff]
Thanks for any help!
