I've used a hose clamp around the split O2 sensor tool to help keep it from flexing.

Brush off the rust and long soak it with Liquid Wrench the night before you attempt to remove the sensor. If you think you need heat, you can run the engine to heat the sensor threads. Just watch what you are doing. Wear long sleeves and gloves so you don't burn yourself. If you get it to move a lit...

Along with the suggestion for liberal amounts of penetrating oil. I have come to favor a certain type of O2 sensor socket. o2.png The one on the left is much shorter and therefore I think is less prone to flexing open. With that said, the use of a hose clamp around the socket as mentioned above is a...

You seem to be missing the 101/102 combo relay.
105 and 106 are the gray ones stamped “Volvo”.

Swap them and see what you get.

Could it have to matter with the the dashboard handset in itself ? To read your initial post, i make me think that the power "goes everywhere" inside. Is there a protection in it that could have been burnt while you've plugged accidentaly the battery ?

Cancel that ETM voltage test. The ETM gets all of its wiring direct from the ECu. Here is the main BuS feed to from the ignition switch. Get an analogue JP meter on the fuse 11B/1 and watch it carefully while you power up, start the far , then turn the light switch on. 11B/1 us in the kidney fuse bo...
