    Hi there,


    I need help! This has been happening over the last month or so, but more "symptoms" have been appearing over time.

    Symptoms:

    - Alarm randomly goes off although car locked/ no tampering
    - CD changer randomly switches to radio/tape
    - Speedo/clock/heating displays dim
    - When using indicators, they randomly stay where they are; similar situation to hazard lights where there stay on when switched off
    - Window will not close properly sometimes when closing the door

    My friend says it's something to do with the relays not getting enough power (/), i.e. low battery. Charged it up overnight, alarm went off twice today, and hazard and door symptoms occurred after charging.

    Any help would be greatly received! Thanks

    just because you charged it than doesn't mean that it took a full charge
    have it tested if the efficiency is less than 70% get a new one
