I have an 02 Reg Madza 323 with the radio and clock not coming on and the cigar lighter seems not to work any more as I used to use it to charge my sat Nav and mobile phone. This seems to have happened after one of my kids put a coin on the cigar lighter socket.
Does anyone have any idea what could have broken? I have checked he manual to see if there is a fuse for this bit there only seems to be or the cigar lighter

Also I don't if anyone has had the problem where alarms keeps going off when the wind blows.

 

With that combination of issues, I'd bet a fuse is the case. The manual may not list everything a fuse handles, so I'd suggest checking the fuses.

Alarm issue is likely caused by sensitivity being higher than necessary. There should be a way to adjust it, but I can't help with that.
