AMAZIN'A4

about a year ago i did the DIY red LED in the dome-light thing, for ambient red light. its been working flawlessly for all this time, but the past week or so have been wierd. the reason im bringing this up is because the light is wired into my sunroof . the past week or so the sunroof has been opening itself randomly. never fully open but just the vent so it only pops open in the rear, and when i turn the dial it will open farther then close back to half vent. WTF the only way to close it is by stopping and putting the key in the door and closing it that way.. anyone have suggstions as to what might be the problem.... also my gas guage and light have been fu(ked up at full tank it works fine but when it hits 1/4 tank the light comes on the guage fluctuates from 1/4 to 1/2 then to below E then to 1/2, what the hell . and when i fill up it goes to full but the gas light stays on for like 15 min. i dunno this sucks. any insight is welcome. sorry for the long post TIA

iirc the switch is the culprit.
