ok when i bought my 91 7 na it was in an accident by the previous owner. it damaged the driver side light completely well i replaced the light assembly but my headlights are always on when the fuse is in. the switch inside wont workk to raise or lower the lights. the 4 ways dont turn on and the headlights dont respond. but the driving lights do also interiors. is it the switch or could it be something else? if its the switch will the switch from an s4 work in my s5?

 

You may have a wire crossed or shorted in the front harness near the relays.
