Cadlillac cts 2005 sun roof not working - where is fuse box for sun roof

None , two - located in the under hood fuse / relay box. fuse # 32 - 40 amp an # 11 a 20 amp . This power the sun roof module , do you know what a electronic module is ? Power for the sunroof switch comes from the module.

Do you hear the sound a motor trying to retract the sunroof? If not it may be the sunroof regulator

battery junction box has 3 fuses to sunroof 1 29 6 interier fuse panel has 3 fuses 1 6 17

Hold down or up the sunroof button for up to ten seconds and then retry. Some circuits such as this type require resetting before they will work again, and this is typically the method for reset.
If this doesn't work, then also check any related fuse.

The sun roof is an electric motor that operates on electricity provided by the battery...
Your fuse may need to be replaced in order to opperate the electric sun roof motot...

CHECK SUN ROOF FUSE.IF GOOD CHECK FOR POWER AT SUN ROOF SWITCH.IF YES SUN ROOF MOTORS WIRES COULD BE LOOSE OR BROKEN OR SUNROOF MOTOR FAULTY.

The sunroof has a relay between the fuse and the sunroof motor

check your fuse in position 38 in the fuse box....this fuse is for the car's alarm system but also seems to work the sunroof, I have a problem with this fuse when its not blown the sunroof opens with no problems but when it blows the roof will not open I am not sure how they are tied in together but they are....so I would say that you have an electrical issue....do not replace the motor until you check this first

Dear cz50001: there are only a few things that you, a weekend warrior can do to diagnose and/or fix the problem on your car.
Unfortunately the newer cars get, the more complex they get.
Unfortunately, your car is one which falls in the more complex category. Your car is designed with a "BODY CONTROL MODULE". This little gem gets input from nearly every electrical component in the car including the sunroof. In terms of what you can do to check it out: The fuse box inside the car has roughly 24 fuses positioned vertically 12x12. The fuse located at the lower left side of the box is a 10A "red in color" is for the sunroof. Remove it and look through it to see if it has been burned through the center. If it has, replace it and try the sun roof. If the fuse blows again, you have a short and it would be best left to a professional.
There is another set of circumstances which can occur that will render the sunroof inoperable. If the battery is disconnected or if the sunroof motor had been disconnected, the sunroof will stop operating. To reset the sunroof memory, with the key in the on position, push and hold the sunroof tilt switch in the forward (up) position until the sunroof is fully vented (tilted up) position. It should at that point operate normally. Should those two suggestions not solve your problem, it requires either a dealership with a specialized tool called CONSULT-11 to communicate with the BCM. There are some specialty shops such as mine equipped to deal with your car as well. However, most can not address this type of problem without this diagnostic tool. Good luck.
