SOURCE: horn doesn't work in car but does work with key fob

Your horn inop problem is in the rotating contact for the horn connection underneath the steering wheel, it is called the clock-spring contact by us techs because that is what it looks like, if you do replace it yourself then you must disarm the airbag or serious injury can result.

CTS are very sensitive to problems with the hose between the air filter box and the intake. If it is not on good or leaks, it will cause the car to run rough, or die immediately after starting.

SOURCE: Replace 2005 Cadillac CTS water pump

drain the coolant.remove belt by rotating belt tensioner cllockwise. water pump pulley will require a holding tool to keep it from turning while removing bolts. access to air ratchet can sometimes eliminate the need to hold but be careful cause thats a good way to skin some knuckles. also make installation more difficult to obtain proper torque. after pulley is off just a few water pupm mounting bolts remain. clean and dry gasket surface very well before reinstalling.

Hopefully you got the unlock code with it, otherwise, write down serial number and model number off back or side of deck, and give dealer a call, they should be able to give you the code .

I need to change my fuse for my lighter outlet in my ash tray in the rear for my 03 cts which fuse is it

If you have your manual, look for the F for fuses, in the index, and it will tell you what fuse and size(meaning 15 or 20 and so on). It will also tell you what components get thier power from that fuse. If you don't have your manual, go to dealers and get one. They are loaded with information that can save you a lot of money
