Clock and cd player in my suzuki swift 05 has stopped working

can only be 2 things
lost power to radio (bad fuse, or bad radio ground)
radio dead. (time to upgrade?)
if not a stock suzuki radio, it can also be the hacked wiring
bad from installing that aftermarket radio ,

sounds like it is wired wrong and look under the hood for another fuse box

I had the exact same problem on my 96 swift. My mechanic found a shortage in the electrical cable going in behind the engine by the firewall. Those cables are to close to the engine and after a while they melt.

That same exact combination of items is on the same fuse in the grand vitara and is a common problem. on the vitara the fuse panel is to the left of the driver's knee. most likely in same spot on your car. the fuse in question was the bottom most forward fuse in the panel. you can just pull them out one by one until you find the burnt one and replace it with one of the same amperage. thereafter discourage folks from using the lighter.

remove all fuses one by one and check wich one is blown if blown replace it and see if radio and clock works

The wiring may have gone bad in your car. Usually blown fuse and loss of power are the result of this. You may need to inspect the wiring loom underneath the dashboard where most of the wiring for the mentioned devices are located.

most of the time there is another fuse that shares another function such as the clock light so you cant see it, it might be on but not light up to see it, go through all the fuses and check if anything else is not working ie interior light etc. if all fails check the bulb in clock then get a multi meter to check for a power supply to the clock. im sure another fuse some where

some kind of loss of power.. have someone check the wiring and fuses

How do I remove the CD player from my 2003 Suzuki Aerio. My CD player doesn't work anymore. What tools do I need?

change new clock
