Welcome to the forum.
The code list has been a useful tool for all of us old timers and new owners alike. Too bad everyone doesn't perform the search to find the code, look it up on the list and then search for answers in the forum, but then that would put a bunch of us "out of business" like a few of the big banks. Hey, maybe we could get bail-out money.
On your question about dash lights. Haven't done it myself (haven't had to) but others have it is a lot of trouble but can be done by a novice. Search for "dash lights" on the forum.
The front end of the cruisers seem to have bad bushings in a lot of them. You'll have to get it up on a rack to find out exactly which ones or replace the whole set.
