Hi, newbie here.
I've got a 2006 Tribeca Ltd. The Tail Lights are out when you turn on the Head Lights. However, the Tail Lights come on when you turn on the Parking Lights (switch on steering wheel). I've checked the fuse (15A) and Relay in Main Fuse Box under hood. Now what? I see a set of blue relays and two 15A fuses under the Steering Column that are accesible after you unscrew the underdash cover, could the issue be there?
