we recently bought a 2004 TSX for our 17 year old daughter her first car, the stereo and heater cliamte control lights are very very dim and sometimes do not work at all,I have been told to replace the whole unit with a used one, so it looks easy enough to remove the old one and install the new / used one and i can buy one on Ebay for about $ 135 CND but i am wonderig if it that will work, is it the unt or the power supply, to the lights, the stereo radio work fine the heater works just the lighs do not work and does anybody have any thoughts they would like share with us? before we buy the new used one
