Hello

Some problems with daughter's Astra J 2010, petrol 1.6.

Right rear indicator does not work, also tail light does not work in right side. New bulb did not help, perhaps earth problem or somethin more serious?? In right side front, both indicators are blinking (quickly) - located in wing and below bumper.

Left side rear ok, blinking quickly. In front both does not work. Heard (only heard) that new bulbs did not help.

Car is 150 km from me so have to take a look when I get it home. Just would like to know whether something typical for Astra to check.
Below is a fuse map from Astra Pages. Cannot find any fuse for indicators. Please help.

The fast flashing is due to reduced load on the flasher relay, usually due to a failed bulb and normal behaviour.

New bulbs can be faulty or incorrectly fitted.

Also the indicators may be powered directly from the body control module so that could also be faulty.

the fact that two different lights on the same unit are not working could be an iffy connection between the plug & the light unit or an iffy earth connection from it.

Thanks for comments, I get the car home on Saturday.

Earths, bulbs etc. simple things (I am just a simple man) I can check. If it is Body Control Module that is something new for me.
If it is that is it expensive part?
Do it have to be programmed by GM dealer or is it just plug and play.
Even if I have left hand drive is the control module in right side of the central console in floor level? All figures welcome.
I report back on Saturday.

There are usually at least two, and they are generally behind each fuse panel.

But start with the simple things... Cheap bulbs, loose bulb holders corroded connections etc.

Also try the hazard switch and see if the failed bulbs are still failed

OK, I thought there is just one.

Are we talking about this unit?

That's one of them, but...

START WITH THE BASICS

[polilara]

OK, OK... Thanks

One body control module on the Astra J and given the front lights are working on that side then I would be checking the ground points also (as they are actually wired off a common FET feed).

Ok, you mean if front main lights are working etc. (I remember they work). So is something grounded with FET (Field Effect Transistor) or is that some kind of slang. I understand basics of electronics so controlling ground side with FET in a car is something new for me. So are these ground points located somewhere else than close to the bulb? Sorry about this language problem...

So the BCM will have a high side (12V) FET (Field Effect Transistor) switch will turns all the lighting for the Right (separate to left to meet safety) side on when the switch or auto lights select. Similarly another separate FET drive will operate the indicators.

The fact you have an indicator and a side light issue you need to consider what is the one common thing for these separate circuits, and the only real thing is the ground point (plus the cable loom, but you would need to lose multiple wires at once which is less likely).

OK, thanks, this make sence. I take a bus tomorrow morning and take the Astra home from where my daughter lives. I am back in the afternoon and start to look this case. I already bought a new toy...

It's allways nice when you "need" new tools. I report back tomorrow.

Astra is home now:

1. In cabin fuse box the fuse No.2 is burned.
2. Internal cabin lights work when door opened.
3. Internal "Map Lights" (separate buttons close to internal cabin lights) do not work, bulbs ok.
4. Sun Visor Mirror light do nor work when mirror flap opened.
5. Left Rear indicator blinks when put on, Right Front wing and bumper indicator blinks when put on.
6. All front and tail lights and brake lights are ok.
7. Tow bar (electricity as well) installed 10 years ago, not tested resently.
8. Fuse No.2 is burned when replaced with new one, door open ignition off, tested twice.

Fuse 2 ad 3 are exterior lights acc to link.

I heard that these fuses have something to do with indicator lights and cabin lights, too.
Urgent help needed, which circuits this fuse No.2 protects. I can step by step start to take wires off if I get info which.
