lupoaht99 Posted October 20, 2023 Report Share Posted October 20, 2023 No auto lock, 1999 Lupo AHT. At door unlock and opening of the door the interior light and fuel pump prim no longer work. Of course first culprit is the lock micro switch, however I took out the lock, cleaned and measured the continuity of the switch. Built back in, measured. Works as supposed. I then also shorted the contacts down where your left foot is (LHD - steer left), behind the covering. Where the micro switch leads to. And still no interior light or pump prime the either. It had some corrosion in the fuse box. Cleaned that off. Still no luck. I now suspect one of the relays , behind the fusse box, or corrosion on one of these. But - can this even be a relay that causes this, or is there simply no relay that has these functions? If yes, which one may that be? Thanks!

mk2 Posted October 20, 2023 Report Share Posted October 20, 2023 Lights on reminder buzzer also not working i'd guess? Tricky, if it's not the door lock. Does the other door make the interior light come on? Thinking aloud... I wonder if the positive feed to the light circuit is working, you know the little wire that gently lights up the light switch when the door has been opened. The wire people use to run trackers and dash cams etc... oh, and is the radio retaining memory settings ok, as it might be the same wire? Can't remember.
