Hello Volvo friends, have a short question about the lighting of the on-board computer. Drive for 4 weeks a 850 station wagon, 2.5 l 170 HP, EZ 95. Have already repaired some things (dome warehouse back, minicat, headlight glass, rear lights). Today I replaced the 4 bulbs ( 12V 3 Watt) of the AI because 2 of them have failed. Was a quite simple thing thanks to the forum here. Now I have found that the lighting of the on-board computer no longer works. Now my question: Is the lighting of the BC related to the bulb of the AI or do I have to change the 2 pears of the BC lighting? Did I also possibly think that it might be due to the plug connection of the BC cable in the AI (e.g. wobble contact). Has any of you had this problem before? The VDO instrument is fixed. In advance already thanks. Cheasy
