Loose Volume Knob does not effect volume 1993 ES300

[Litefoot]

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.
