headlights will not go out with switch or auto feature. we have replaced the headlight switch. headlights will go out when breaker is removed. I have read that it may be the body control module. any ideas?

the headlights go into the daytime running light module so that may be bad. any mechanic with a pro scanner can scan for codes to see if that is the problem. It probably is if everything else has been checked.
