I have a 1999 Cadillac Deville. It has the a/c codes and is full


one way that could work is to disconnect the battery for a few minutes. some models won't do it. the only other way is to take it to a shop that has a scan tool and have them clear it. did the person that told you the codes must be cleared, tell you what the codes were? it is possible to purchase and inexpensive code reader that is capable of clearing codes

My sisters cadillac has a check engine P0300 code. I have looked into this but wanted a shorter list of what it could be. Can u help?


Hello... I don't think there is a shorter list.... The code, as you probably know means the vehicle is having random misfires... There are about 10 things that can cause that based on other symptoms.

Is the vehicle having other symptoms. That may help narrow it down... Also, are there any other codes present....

Good Luck...

Anybody know what the colour code is for the 94' Cadillac Concours , i can't find it anywhere? It's the pearl white colour. where is it located on the car?


White Diamond Pri Metallic Tri-coat 93/WA8933
 Paint codes can be confusing! For example, the color code 93/WA8933 listed on our site can be shown on your vehicle as 93U or 93L or8833 or WA8933 Often there will be a BC CC before the color code. This stands for Basecoat/Clearcoat. The U in the paint code means theUpper Color and the L means the Lower Color. Two tone vehicles will have each color coded, i.e. 93U and say 93L. Also, it could be 8933L or8933U.
Good luck and hope this helps.
