Guest Mc_Reatta Posted December 25, 2009 Share Posted December 25, 2009 Can someone tell me where the courtesy light module is in a 1999 Olds 88? Link to comment Share on other sites More sharing options...

Guest Mc_Reatta Posted December 28, 2009 Share Posted December 28, 2009 Thanks Paul. I let you know if I find it. My courtesy lights won't shut off, had to pull the fuse. I hope I can find one, Old's dealer situation not so good around here right now. Link to comment Share on other sites More sharing options...
Oldsfan Posted December 29, 2009 Share Posted December 29, 2009 Any GM dealer can order one. GM has limited stock at 3 warehouses. Sells for around $125.Looks like if you drop the knee bolster below the steering column, it might be just under the column.Paul Link to comment Share on other sites More sharing options...
Guest Mc_Reatta Posted January 18, 2010 Share Posted January 18, 2010 Unfortunately there are at least 3 modules in there and nothing's labeled. searching for a part number so I can find a picture to narrow it down.Thanks Link to comment Share on other sites More sharing options...
Guest Mc_Reatta Posted January 18, 2010 Share Posted January 18, 2010 I think I found the module. Checking a black module PN 25269373 I found it is called the module interior lamp, but it has only 4 wires connected to it, and disconnecting and connecting it made no difference to the lamps - they still stay on all the time. There has to be something else controlling them. According to the only diagram I have, that relay should be the only common ground for these lights. I don't think the remote accessory control module can turn these lights on without using the this relay module, so it looks like I have a short to ground of on of the many white ground wires from the lamps to this relay, or one of the independent on/off switches in one of the lights has broken and is grounding the whole circuit.Anybody have any ideas of where to start looking?ThanksMike Link to comment Share on other sites More sharing options...
