This is very, very good Saab DIY video from Aaron Zollo editor-in-chief of Zollotech. Many Saab 9-3’s (2003-2006) have their climate control buttons wear away.
To replace them and make the buttons look new again isn’t too hard, and just takes patience. This video show you how to replace worn off buttons on an 03-06 SAAB 9-3.
Replacement keys can be found on many Saab webshops, and the author of this video has got the replacement buttons here ($77 – oemsaabparts $78; skandix 119€; Ellis Saab Parts $72; Ebay $69.99; PFS Parts 104€).
Also, for the operation of replacing the buttons you do not need any special tools. Good enough is a handy tool that has in every household.
