Radio volume problem


I tried searching in the forums but didn't find a similar subject. If any one can help would be appreciated.

The original radio on my 67 Parisienne at times doesn't respond to volume changes. In other words, the volume becomes what it wants it to be, often very loud. Turning the know doesn't change anything but at other times it works well.

Has anybody ever experienced the same issue and if so, how was it resolved?

Sounds like the rheostat has become oxidized. I like to use  Electrosolve contact cleaner. Safe on plastics and  varnish on  wiring. If you pull the volume  knob off you may see a small hole where you can spray  a small amount of cleaner using the small spray tube. Rotate the knob fully to the left and right. image.jpg

Available at Active Components or your local electronic parts supplier.

Pete, thanks for the advise. I pulled out the knowb, then the spring and finally the tone knob but found no small hole. I guess the spray will go in the middle.

Where can you find this product? I found a general contact cleaner at Canadian Tire.

RE: Radio volume problem ONLY WHEN BELOW 25C


Hi guys

After taking the radio out, cleaning it and trying to adjust the trim I've had little success but had the following surprise: it seems that when it's really hot out such as over 25C the volume control works perfectly well. There must be some metal expansion and contraction that causes this but I can't figure out where. In the meantime due to high temperatures the volume works fine.

Does anyone know what to do?

Radio volume problem


As Pontiac states, you've likely got a bad rheostat in your volume control. You'll need to pull the radio out of he dash, take the bottom and/or top cover off and look at the back side of the rheostat. There is often a small opening where you can spray contact cleaner. Also check for bad solder joints while you're in there. If you're lucky, that will fix the problem.

I was going to suggest the same thing as Clint. It wouldn't hurt to reheat most of the solder joints and even add a small amount of fresh solder. The original radio in my 58 Plymouth came back to life afer doing that.

Also, most people smoked in their cars back in the day and the smoke was really hard on the rheostats so a good cleaning will likely help.

Your local auto parts store should also have some contact cleaner.
If all else fails, you can try some WD40, but it may not have lasting results.

Could be a dry joint in a component connection on the board somewhere. Need to look close at where all the legs come through of each component. Instead of solid solder you might see a ring around the component leg.
