Has anyone had a problem with thier sterio speakers. We have one that periodically sounds louisy.

The daytime running lights aren't working correctly either. The regular headlights are always on.

These are minor things and the only problems I have had in the 3 years 26000 miles. Wonderful truck, just wondering if these are flukes or common repairs.
Thanks

About the speaker-
It may be a loose connection... my dad's explorer has that problem too, he just turns the rear speakers off when it happens and the problem is fixed :)
