Alright im not a car expert so excuse my noob language if i don't explain myself exactly right. Heres the problem, I was installing my dvd indash with my friend into my 300e the other day and i had to remove the ashtray and the heater controls and panelling covering it. The problem is once i installed the deck i had to put the wire harness connected to the heating controls back together but of course somehow they became undone and we have no clue what order to put them back in. Theres 12 wires and we put them in there the way we thought but obviously it was wrong because now my heat won't turn off and is on blast mode. If anyone can make any sense of what im trying to say and wants to help me, I'm taking any help i can get. P.S. if your response is going to be go to the dealership, im too poor to waste the money.lol.
