Hi, Been trying to figure out the letter/number combinations from my Service Parts Identification label. Nearly there but missing a few. Anybody knows and can help out these last bits? Thanks Anders
Don't really know about any GOOD Buick forums. I prefer this forum as the car is a Wagon and you guys knows more about wagons than other Buick forums. Also a 1987 is to new to be of interest on a regular Buick forum. But the codes are GM codes so it should work with any GM car. Most of the codes I found in my parts catalogue and online at a Chevrolet site.
Here are 2 sites but when in doubt, just google it and you might get lucky. http://www.angelfire.com/ny2/96transam/rpocodes.html http://www.rpocodes.com/
I do not ask a question without first searching extensively for the answer. As you can see from my list I have found most answers indicating that I have done my job. Its the elusive codes that's been impossible to find through google or the library, yes I have good manuals, and that's why I ask. A generic answer like searching the web is not helping at all. Going through the angelfire site I find that YT9 is marked as ??? 31U is marked as "PRIMARY COLOR, EXTERIOR, ARCTIC WHITE PEARL (92)" which is incorrect for my car as my car is dark blue. The rest of my blank codes are not even stated on angelfire. Same with second site.
By googling....I mean you might get lucky with other GM forums and those guys' responses.
