- The error code you're getting has to do with the laser lens not being able to read the discs. This is either because the lens is contaminated (dirty), or faulty (needing replacement or is misaligned). The first thing to do is to purchase a CD/DVD laser lens cleaner disc, and run it through the system several times.
- These players are famous for messing up. If your good, you can pull it out. Take it apart, pull the cd's out. Put it back together. Don't ever put a disc in 1 or 6, and your set.
There aren't too many places that repair these things as it's generally cheaper to replace the unit. If you can't get it working and just have to have the stock look, you could try getting a replacement off eBay or from a salvage yard (although the vehicle is 23 years old, so that's easier said than done).
