Dds1994

Brand new member here, just purchased my first corvette, 1994 with 63k miles. I am going to attempt to remove and clean my climate control per instructions posted here. My question is mine is working fine except the indicator lights. Can anyone advise if replacements can be purchased and where or will cleaning the contacts and the board take care of it.....By the way this site and its members are great I have learned a lot in a very short time....
