So can someone please help me with this problem, my cd changer on my 99' rx300 doesnt work, it says error 2 when i try to play it. I guess that means CD jam. But there is no cds and i have tried other cartridges. Also i was wondering too if anyone else has problems with there driver side window coming back down when winding up because it is pinched but not. Anyways the cd changer is my real problem.
