i don't know if this is bad or not to be honest, i put in more then half tank of fuel which was about $50. and i got 195k's out of it?. it's like if i drive my car slow it use's more fuel? its like i have to keep the foot down every where i go? wtf.. #2 i was driving an heard this sound wouldnt go away i was getin so pissed off because i couldnt find it then i look up and the sound was coming from my light on top of my roof ( if u get what i mean ) it wont go away!. maybe water got in it an its making a ugly sound.
The sound coming from around your interior light would be the fan for the ambient temp sensor. I've tried pulling it out and lubing it up with Vaseline, quieted it down a tad but it's still annoying.
