Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
The front bumper fascia has to be removed to replace the DRL bulbs so if you are not prepared to pull the grille and fascia off you should leave this one for the dealer. The "book" time for this is 1.5 hours so it is no small feat.
If you have further questions about the procedure let me know and I will do my best to help you
