I just bought a 94 850 wagon, it's been very well maintained and I really love it. However there is one problem that I want to fix but want to make sure I investigate the correct problem. When you turn the volume knob on the stereo, with each 'click' there is a static sound and the speakers on the passenger side go in and out. If I jiggle the knob a bit the speakers will go back on (sometimes still cut out). I want to replace the problem but unsure if it's the radio or the speakers I should be looking to replace. Any help or advice is greatly appreciated.

Thank you!

Don't spend any money to repair it if it comes to that. You can pickup a SC-816 stereo/CD player off of Ebay for about $200 that plugs right in. Or you can trade in your old SC-811 for a new SC-816 at the dealer for a little more. To remove the old radio just push the two flush tabs in quick (those vertical tabs on either side of the lower face-plate), and they'll pop out then pull the radio out by the tabs. You kind of tap them in quick and they pop back out, releasing the radio. Make sure you have the security code before you take power off the radio though. The new radio/CD will come with a new code. Everything is plug-n-play.

I agree with Ray...don't replace because of this. I had the same problem with my 850 and used the contact spray from Radio Shack, spraying it in where the volume knob shaft goes into the front of the unit. It fixed the problem!

thank you!! I went to Radio Shack last night and picked up that contact cleaner and it worked like a charm! Then I promptly went to Ebay where I won an auction for an Alpine CD Changer for my model radio for $125 (which seems like a steal!). So thanks again, hopefully I'll be able to figure out how to install the cd changer, hoping to place it in my glove box.

Thanks!!!

stick it in the boot as per factory standard....takes about 2 hours to install! also its VERY tight getting it in the glove box...

Piece of cake to put changer in glovebox. Just need to drill a hole in the bottom of the box for the interface cable. My CHM S630 fits so snug no additional mounts were needed. Depending on the model changer you might need to hookup to a constant 12V source on the H/U to enale you to eject magazines with the power off. Either way, no big deal. I think the 620 and 630 are the same size.

The volume control is a rheostat which can become dirty over time.
You can use TV cleaner sold by Radio Shack to help with this. You
spray it into the switch and turn the knob back and forth a few times.
The best way is to do it inside the radio (with the top off) but
you might be able to do it by removing the knob and spraying a
bit of the cleaner down the knob's shaft (depends on how long the shaft
is that connects the knob to the rheostat). A car stereo shop might
do this for you for a couple of bucks during a weekday time when
they are not busy.

Note that some Volvo radios use a digital volume control (The 816
model is like this). Don't spray cleaner in a digital control. The
digital ones have a volume control that can be spun either direction
without hitting a stop. That is, you can spin them 720 degrees (or more).
