Hello there. I have a 1995 chrysler concorde with less than 55,000 miles on it. Yes. 55,000 miles on a 26 yr old car. I know. But my issue is that my air bag light has come on. I recently bumped into something on the front end. The air bags didn't deploy or anything. But the light came on. I've been looking for a front impact sensor. But I haven't found a single thing telling me anything. I don't even know if it has it. Nor can I find a diagram of the fuse box. If anyone has any idea what all might have caused it? I would truly appreciate it. Thank you.

AIR BAG WARNING LIGHT
Whenever ignition switch is in RUN or START position, AIR BAG
warning light on instrument panel will glow for 6-8 seconds and then
turn off. This signifies ACM has checked system and found it free of
problems. If AIR BAG warning light glows for 10 seconds or more, stays
on at all times, or does not come on, a system malfunction exists.
IMPACT SENSORS
Three impact sensors are used. Two impact sensors are mounted
on headlight carrier surface on left and right sides of vehicle. Two
impact sensors are located on radiator support behind grille opening
reinforcement. ACM contains the third impact sensor, which is called
the safing sensor. Impact sensors are inertia switches which complete
an electrical circuit when a front-end collision creates sufficient
"G" force. For air bag to deploy, safing sensor and at least one
impact sensor must activate at same time.

AIR BAG CONTROL MODULE (ACM)
ACM is located in front of center console. Impact sensor
(safing sensor) is an integral part of ACM. The ACM monitors critical
input and output circuits within air bag system, ensuring they are
operating correctly. Some circuits are tested continuously; others are
checked only under certain conditions. The ACM provides information
about air bag system through AIR BAG warning light and ACM data link
connector. A fault code (message) is stored whenever AIR BAG warning
light stays on for 12 seconds or more.

I have been constantly searching online for a part number. Or an actual part. I haven't been able to find a single one that fits the car. Any ideas where I should or could look?

Part number for the ACM (Airbag Control Module) is: 4759742 There are several on Ebay.

Part number for the Front Airbag Sensors is: 4728374 This is a discontinued part and none are available on Ebay. Probably only way to get one is from a junkyard. 95-96 Concorde/Intrepid will work. And late 1994 LH cars possibly. You'll need to find one that hasn't been hit....preferably in the junkyard with a bad engine/transmission.

I suspect it's one or more of the front sensors that's the problem. But it's also possible the Safing impact sensor in the ACM is the issue. The ACMs on Ebay are pretty cheap....some as low as $23.17 total shipped. You could also check with the seller to see if they can provide the front impact sensors also.
