Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
This is not a common issue on this model.
The bulb would not work if the fuse was blown.
Did they address the condensation issue with the headlight assembly? Condensation buildup can result in bulb failure because the bulb is very hot and any water on it can cause the bulb to fail. Do you own a volt meter so we can confirm the bulb is getting power and ground?
This is my 1st answer, but does not have to be my only answer. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. Please let me know if you are pleased by selecting a star rating above or by replying and saying your pleased. Not rating or rating 1-2 stars does not benefit you nor me in any way. Follow up and reply as often and when needed, there is no extra charge to do so.
I am familiar with the condensation concern, but there are no messages from Cadillac on repeat bulb failure without condensation. If you can do some diag I can help you figure this out.
Hello again Chris here,
