Forgive me is this is the place to post.
The decal for RPO codes in my glove box is unreadable. Is there a way to find out what I have by VIN # someplace?
This link below does a pretty good job of decoding my 1999 K2500.
www.free-vin-decoder.com
Looking over the list of RPO codes it reports for mine, it seems to be accurate. There are 62 codes on my glove box sticker/label and that site has the same number for my VIN.
The description of the some of the codes may be a little off.
For mine @ free vin decoder it says UQ3 is "AUDIO POWER BOOSTER"
Then
HERE it says UQ3 is "SPEAKER SYSTEM,PERFORMANCE ENHANCED AUDIO".
Might want to double check some of those descriptions.
Best of luck.
