2005 hyundai sante fe, the D/S switch button for lock of power doors does not operate. All other buttons operate locks the way they are supposed to. The key remote to lock and unlock all doors also working properly. Have tried a complete switch assembly I got on ebay and it does same with that on elock button. I checked and changed a relay, but believe it is one which operates remote since it clicks with remote. Elecric mirrors is also part of whole switch I changed and it operates properly with old and new, so I have ruled out ground since it appears to share common ground. I look at wiring diagram for system and it appears that there are two more relays , one for lock and unlock in addition to that remote ant theft relay which i tried. Is it possible on e relay is out and where is it located. I can hear low click when i push unlock button with the D/S switches, but cannot locate. How burried could they be and why doesnt fuse box diagram show them. Also is it possbly wiring from switch thru door to relay. Any help would be appreciated.
