    All Indicator Light Permanently Illuminated

    Here's a strange one (to me at least):

    I backed my Sumo onto the drive for a quick hose pipe and sponge bath and then left it in the sun to dry. A couple of hours later I rolled it back into the garage and made preparations for a family barbeque.

    A couple of G&T's into the event my daughter told me that the garage smelled of "hot car" and that all the indicators were on solid. I don't think the smell was anything out of the ordinary but sure enough the lights were on.

    I pressed the hazard button and no change (I didn't hear the relay clicking, either) so I simply disconnected the battery earth and went back to turning sausages.

    When our guests had left, I reconnected the battery and the lights were out and the hazard button worked as expected.

    That was the extent of my fault finding; I just left the battery disconnected and reviewed the Haynes manual's wiring diagrams for an obvious source of such a failure (didn't spot one).

    Anyway, has anyone else seen such a failure, temporary or otherwise?

    sounds like you got wavy with the hose and its tiddled into your electrics.
    personally I have never used a hose to clean one of these cars as I know I'd end up squirting the interior.

    If not to difficult, remove the flasher unit relay and if you can, remove the plastic cover
    so as to drain of any water especially if the relay is mounted upside down, that's
    normally the way to get water ingress.
    Check any others that you may suspect at same time.
    If you leave the relays to dry out naturally you do run the risk of damage .
    Should only be a very minor issue,
    Chris.

    Wot Kevin said. Water is a lovely conductor and easily bridges small gaps. Fortunately the hot weather at the moment SHOULD dry out the relays. But it may be worth removing them and giving them an air bath.

    Cheers. It's not the first time I've washed it this way but I'll see if I can find any damp components.

    The fuse box (right side of driver footwell) and flasher unit (above driver's right knee) are dry as a bone and no visual sign of previous water ingress.

    Looking at the wiring diagram again, so many things would have to go faulty for the indicators to come on permanently with the ignition off that it makes that unlikely.

    However, the alarm that's installed does connect to the right and left hand indicator circuits. I still can't find any sign of water on that, either, but it's more believable that it decided to apply 12v to them for some reason.

    If it happens again, I'll disconnect the alarm from the indicators and see if they go out.

    I still think your safest option is just to stay away from the hose
