LEFT SIDE, FRONT LIGHTS wont turn on

[07' Ford Focus SE]

Hello there, my front lights on the driver side do not turn on (headlight, reg light and fog light) I have been monitoring the issue and 1) there is a contact issue in the fog light. 2) when it is too cold the reg light wont turn on. and the headlight its just burnt. Wonder if all these issues on this side are due to the contact problem on the fog light. how do I address this? any advice? thanks

Have you checked the wiring to see if its exposed?
