Hi I bought an es300 which I bought in December and daily drive. The volume knob is broken, power steering leaks, and I lost the tab for fixing the fob as Lexus doesn't make fobs or windshields anynore for my car (I need a new front windshield mine looks like someone shot at me. Was wondering if anyone could recommend a replacement for the audio stack, should I tear out my carpets, replace my loud muffler or worry about the broken glass? I am just doing the right rings like fuel filter, oil filter and, air filter so far.

The volume knob seems to change the station randomly if you spin it but thats it, and does not effect the volume of the car. It is very loose. Much less tight than that of the heating. When we take the volume knob off the metal piece that clicks into the back of the knob is loose. Pushing it in does nothing. I also need to make the window regulators work, and also my heated seats are stuck on the passenger side is stuck in the low position. That is all folks bought this Lexus for 300. I really like it. Came with straight pipe. Could use a radio because the sound of it is very loud. Thank you.
