Question about 1994 Pontiac Grand Am
A 1994 Pontiac Grand Am. Have been told it is the Multi Function Alarm Module that is faulty. Interior lights no longer work, fuses are all okay. Anyone have any ideas where someone can find such an item? Thanks.
The Multi-Function Alarm, Engine/A/C, and SIR Crank In-line fuses are located behind the I/P fuse block taped in the harness.

Probably a broken ground wire. Check it with a test light. Make sure you have a good ground, and then stick the test light right in the socket to see if there is power. If there is power to the test light, but still none to the bulb, it's a ground wire. If there is no power, its a power wire. Just keep poking the wires, and work your way back until you find some power. Make sure you have the lights on when you're checking. Good luck.

i have the sameproblem. Dealer part was quoted to me at $510.00. All after market parts stores were $350- 450. Try moving the emerg. flasher button while you step on the brakes and someone else watches the lights. I jammed paper beside the button and they work until I can fix it.I had to order the multi-function switch. and you have to pull the air bags to replace it.

I'm a little late but I can add a couple off things.
1. the fuse goes to the body control module (BCM) under the dash. From there power is distributed to two different circuits. Unplug the body control module, install a proper amperage fuse and see if it blows. If it does the problem is in between the fuse block and the body control module.
2. If it doesn't blow, This is a little trickier but you can narrow down the source of the short to the specific circuit that the BCM controls. with the fuse installed and the BCM unplugged you can find the orange (pin 50 - Connector 1) and jump it to the grey/black wire (pin 43 - connector 1). if the fuse blows than the problem is the courtesy lamps, reading lamps, or dome lamps.
If the fuse does not blow than jump the orange (pin 50 - Connector 1) wire to the orange wire (pin 44 - connector 1) (yes they are both orange). If the fuse blows than the issue is with the the vanity lamps or the trunk light.
The wiring is a little more complex than what I have described above but at least you can narrow down the circuit that is causing the issue.
This seems like a simple problem but it can turn very complex in a hurry. If you are not comfortable with automotive wiring or have little experience with automotive wiring I would not suggest trying any of the above. Jumping the wrong wires can cause more problems than they solve so please consider this before attempting the above.
If you have any questions let me know and I'll be happy to help. Thank you for using Fixya.com!!
