We bought a 2002 renault Laguna 1.9dci sports tourer 2 weeks ago and although we love the car have a few problems. The left indicator light(back, side & front) will not go out. The light stays on continuously, not flashing, even once the car is not running. The last two nights we have locked the car and the light is off, checked again before we've gone to bed and still off but our neighbour says it was on when hes gone to work in the morning and subsequently the battery is normally dead when we go to start it as its been on most of the night. We thought this could possibly be a fault with the immobiliser/alarm but not sure. Does anyone have any ideas that could put us in the right direction, we would be very grateful.

Could be a poor earth connection.
May even be something as simple as a fuse with a poor connection.
Would be worth looking at the fuse, removing it and refitting it. Also checking that the relays are correctly located.

It is unlikely to be an immobiliser or alarm problem. That would probably involve the alarm continually sounding all night as well!

Lights on by themselves

It don't look like a poor connection otherwise it wouldn't light - it's more likely to be getting a connecton when it should'nt. The fact it came on on its own would suggests the possibility that water is getting in somewhere and I would start by looking at the fuse boxe/s and the relays. Just as a matter of interest did it rain overnight this occured.
Keep us posted.:)

That's more or less what I said. Poor earth connections cause a whole load of unusual faults.
Poor connection can be classed as damp. If the relay or whatever isn't making a solid contact that could be why sometimes the lights go off sometimes it doesn't.

Thanks to you both for your responses, ok when my partner got home he jumped started the car and the light was out which was great however after taking it for a spin to put a bit of charge in the battery, we went to lock the car using the key card and when the indicators normally flash as the car locks the left one came on and stayed on. We unlocked the car and locked the car a few times but the light just stays on. We have had a look at the fuses in box 1which seem fine when you take out the fuse for the indicator it goes off obviously but comes back on when you put it back. Fuse box in engine we haven't touched as manual says not to and we dont want to cause more damage. Where do we find the relays? cant seem to locate them at the moment. It did rain last night but didnt the night before and it happened then also. We have rung two garages locally and both say they wont touch any Renault electrics as you end up causing more harm than good!

It does sound like a problem with alarm or locking.

Does it say anything in the handbook?.Sometimes a certain fault is indicated by the indicators staying on.Also,it could be the battery is faulty which causes the light to come on,rather than the light coming on and flattening the battery.If the car electrical system drops below 10 volts or so it will cause allsorts of strage things to happen.
