I have a 1996 Buick Park Avenue. Interior lights will not

Resolved Question:

I have a 1996 Buick Park Avenue. Interior lights will not go off when engine is shut-off. Had to pull fuse to keep battery from going dead. This killed power to the power seat as well. Fault does not appear to be due to dashboard controls. Has to be a module/relay somewhere. What is it called and where is it? Can't find any reference to such a control at any online gm parts supplier or auto parts company. Need to know if it can be done by shadetree. Don't want to have to pull dash but otherwise am very handy. Also need part no. and approximate cost of part. Does not have to be exact. Thanks, Stan

Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.

 

 

Voltage is applied at all times through I/P Fuse Block CTSY/PWR MIR Fuse to the Body Control Module (MALL). When a door is opened or the Interior Lamp Control is operated, the MALL Module provides a ground path to the Courtesy Lamps. The Courtesy Lamps, which includes the Rail and Warning Lamps (if equipped), then light. After the closing of all doors, the MALL Module will provide the Interior with a ground for about 25 seconds, provided no other inputs are received.

 

 

 

The data base doesn't show the part number for it. You will normally have to go by the numbers on it and you will need to get it from GM.

Do I have to take the dash out to fix it? Or is it on the passenger side under the dash? I am not worried about any problem with getting the cover out under the dash just with getting the whole dash out.
