    Third brake light out...

    I have a 08 Cadillac DTS that I love but have recently come into a few problems. The third break light bar has a few lights out, and I hear that I am going to have to have the whole bar replaced? Also, the left speaker comes in and out when driving which is annoying and now my darn warning signal comes on and reads Lane Departure needs service. Anyone have any of these problems occur with their DTS?

    Yes the 3rd light have tobe change as one unit because is led look for one on ebay could find them thereon the speaker take the door panel of maybe the connection to the speaker is loose.

    Ninibtrue, would you consider taking your DTS to a Cadillac dealer for service? It would be a great next step, and please let me know if you would like any assistance working for your dealership towards a resolution. I'm available via email at Katie_Lucille@gmexpert.com!

    Best,

    Re: Third break light out...

    I was able to buy one from gmparts direct or similar site for around $100. It was very difficult to get the old one off, the mounting studs that are attached to the brake lamp assembly in a way that they break off from the plastic as soon as you try to loosen the mounting nut on the underside of the trunk, so the studs are just spinning in place. Not fun

    so you would suggest not to get a used one? So ebay would be ok? I have a few ones out in mine as well.

    Re: Third brake light out...

    I was taken for $295 at the Caddy dealer two years ago. I wish I new about this board and ebay back then. Sorry to get off topic I know I will be in trouble for not starting a new thread but Sub, in you're albums you have a picture of a tranny fill cap off showing no fluid. I have read you're posts explaining in great accurate detail on why no fluid is visible looking down or on dip stick when cold ( not running ). My question is do you know why on the dip stick it has a cold reading about ( bottom to half way up the stick saying cold then the rest to almost the top saying hot ). The only thing I can think of is it is for people that would not run the engine ( drive far enough or long enough to get a proper reading of hot. I hope this doesn't sound to stupid. Sorry for asking this in this thread.

    ^^^ Exactly the reason for two sets of marks on the 4T80E stick - the fluid expands when sufficiently hot - COLD is to get the fill level in the ballpark for post-work startup, then you do final after-test drive hot level checks.

    Wow, that's cheap. I just ran a price quote at the dealership I work at, and it's roughly $400.00 + tax installed for an 08 DTS third brake lamp assembly.
