Regular Production Option (RPO) Codes
In the glove box of your Blazers/Jimmys/Bravadas is a Service Parts Identification Label (SPIDS) with a bunch of 3 digit codes called RPO codes. These codes tell you what options are on your vehicle. The following link will allow you to type in your RPO codes and translate them for you. You can then copy the contents from the description page to MS word, or Notepad (I used notepad so as not to copy any HTML over) and print them out should you wish to do so.

Also, here is what I have found to be the ultimate RPO listing (188 pages of eye splitting RPO bliss) - Hope you have your reading glasses on!

This was excatly what I was looking for! God bless the search function! It saves endlessly repeated questions! My friend that bought my truck asked me what tranny it has and I was clueless. Thanks 93LT and swart!.
Actually, the link works but there is nothing there...
You can try to put your VIN into compnine.com's VIN decoder. It is limited to how far back it goes though. If that doesn't work, then the dealership may be able to run your VIN, but there records have a shelf life too.






And if ya were board enough had your codes typed into MS
