How to replaceheadlamp module relay 35 on a 2005 Buick LaCrosse?

The fuse/relay box is under the hood on the passengers side. The box is located between the battery and the firewall. I recently had to replace the same relay after my headlamps stop working on low beam. This relay is located in the number 11 slot. I understand this is a common problem on the Buick Lacrosse. Hope this helps.
