"Blowing" FusesFuses and Circuit Breakers are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] from short circuits and overload conditions which can cause extreme overheating that can result in damage to the insulation and the conductors, and worse, the possibility of a FIRE which could destroy the vehicle. When a fuse, and replacement fuses blow, especially if it happens repeatedly, is an indicator of an UNSAFE CONDITION in that circuit, usually a short. The proper "fix" is for a qualified technician, who knows what he/she is doing, to troubleshoot the circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse]. Some ignorant few will suggest installing a larger fuse to solve the problem, BUT that will only amplify the problem, not solve it. Do not install a larger fuse in a misguided attempt to correct the problem. To install a larger fuse would almost guarantee damage to the wiring and an electrical system fire.

What can you do if a 99 Chevy Malibu lights come on when the door is closed and the engine is off killing battery?
First verify that you do not have the interior lights switched on using the panel (instrument illumination) dimmer switch. Verify that door switches are working normally and doors are closed. Then, if all of that is well and you do not have any damaged wiring, replace the BCM. Also, you could pull the fuse out, but then you wouldn't have any interior lights. Ditto if you pull the bulb out.
