thanks carnut , but how do i erase the codes related to climate control? and i had the freon checked ...they said it was full.?

 

Log onto www.cadillacforums.com Go to the Sedan deVille section and click on the sticky regarding pulling codes. Good tutorial. Erase ALL codes. It will also list codes and what they pertain to (A/C, suspension, timing, etc) Or....... if you look at the forth post down just above yours, the procedure is listed. Without the compressor engaged, no shop can verify freon level.

 

codes, pull, erase, tutorials are here:
