i broke my wife's side mirror,passenger side. i already ordered the part from the dealers for $70 and was told that they would charge me $98 for the installation. the whole side mirror is still in tact,it's just the mirror itself that got shattered. how do i go on changing this? i do not want to just prop i out for i might break something if i do that,the side mirrors are also heated so i do not want to break any wires by just pulling it out. $98 is too much if i will be taking it to the dealers.
