My right lamp is out but my brake light still works. When I drive I only have one tail light working (left side). When I put my right signal on it works but it flashes fast I do not know if I need a whole lamp or is there a replacement lights. I do not want the police tripping on me with one tail lamp on. Please I need answer on what to do.

Hello,

I would check the light bulb first but then hit up the fuse becasue if one fuse is out it will cause this problem.

Here are some guides that will help you get the problem fixed:

and

Here are the brake light diagrams and a guide to help you do some testing:

Please let us know what you find. We are interested to see what it is.

Cheers, Ken

Need to remove tail light housing to check for water leak into tire jack well on right side. I already replace the tail gate weather seal.

There should be a couple of screws you can see once you open the lift-gate. If you have a water leak you should have the spare out and lift-gate closed then have a helper spray the back end of vehicle and on top to see if you can see the water coming in.

How do you replace tail light bulbs on vehicle listed above SUV? Both brake light and turn signal. I have found answers for sedans but not SUV. Are these led lights and is there a video? Thanks

You need to open the rear tail gate and loosen the trim/carpeting first to gain access to the light assembly bolts. There should be plastic fasteners holding the trim on. Once removed you can see the bolts holding the assembly on. Remove these bolts and pull the tail light assembly out far enough to reach the bulbs.

Here is a guide that can help with a diagram below:

Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.

The front running lights that are also the turn signal lights in the front. Amber colored. Most GM have white lights like headlamps as running lights, but not for
Cadillac. I cannot seem to find a way to get to the headlight assembly without having
to take off the whole front grille or bumper. Baffling! A simple lamp to replace
but how to get to it?

If you open the hood, check along the rad support for vertical pins that hold the assembly in place. Some used these. If they are there, pull up on them and the assembly will come out.
