I agree with all who said the contacts are dirty. Working in the electronics industry, I see this all the time. Dirt, dust, grit, sticky residue will cause a faulty volume control. Use contact cleaner, but be careful not to spray the plastic ****, because it will discolor the plastic. Also as stated before you can use denatured alcohol or sand,or use a very fine file on the contacts. Also you can use compressed air after cleaning and sanding, this will remove any moisture that has accumalated. Contact cleaner can be purchased at any electronic parts supplier and some auto parts stores.

After you remove the trim then the volume control unit will be held to the trim with either screws or clips. Now disassemble the volume control unit VERY CAREFULLY and follow my steps. It seems you have limited knowledge of mechanics so ya might want to find a friend to do this. Good luck

I don't have my car with me right now but I think you have to remove the shifter ****, remove the panel around the shifter, and there should be some 10mm bolts that secure the trim at the bottom. After removing the bolts the top section is held on by clips. To remove these clips you must pull the trim out toward you being careful not to break the trim. It's been about 2 years since I've had it out so my instructions may be a little off. Yeah you may want to have someone else help you...maybe a friend who installs stereos professionally and understands the basics around interior assembly. Good luck

I just got off the phone with Carson Toyota. They said a brand new radio **** is only $6. I'm going to go this route, since I would spend more than that for the cleaning alcohol, as well as time spent if I removed the existing one and cleaned it. There is also no guarantee that cleaning it will fix it, or that it will become even more damaged.

I take back everything I said in the last post. I guess I'll be cleaning the old one afterall...

If you want to replace the volume control with a new one, you must remove the trim piece because the control is installed from the back.
If you want to clean the existing control with contact cleaner, you must take the trim off to remove the control so you don't damage the trim or the **** with the contact cleaner - it is basically aerosol drycleaning solvent, and it will ruin plastic finishes. You can buy it at Radio Shack.
So, bite the bullet. Do a search. Removal of the console trim has been covered a lot here. There are pictures of the procedure on the LSOC site.
Then try to clean the control with contact cleaner. Look for openings in the body of the control once you get it off the trim piece. Squirt the cleaner into the holes and spaces and then work the control min-to-max a bunch of times before the cleaner evaporates. Then hook it up to the radio before you put the trim back. If it sounds better, assemble. If it doesn't, get a new one, assemble, done.

I just fully cleaned mine - Took the console out, removed the ****, opened the volume control up, ran some high-grit sandpaper over the brass contacts, used a Q-Tip to clean the electronic contact area, reassembled and presto, works perfectly!

Just as another follow-up. I had exactly the same problem and did exactly the same thing - took apart the volume control, sanded the contacts, cleaned the contact surface and replaced and now it works perfect. I also have a spare volume control now that I can do the same service to and sell for cheap if anyone needs one and doesn't have the time.

Not sure if is the same problem, but the radio **** on my LS400 was "loose" I pulled off the **** and what had actually happened was the nut behind that **** had came loose. Tightened it up and all was fine.
