I have a 1944 Mercury marquis. Air bag code 44 is flashing

If you have air bags in a 1944 Marquis, that's likely a retro-fit. I don't have any information on that... :eek:
However, if you mean a 1994, we can talk about the RH Primary Crash Sensor and check to see if it's connected and mounted properly onto the vehicle.
Has someone been working on the right front of the car? Like behind the right front bumper, just near the base of the rediator? You may find the harness and/or sensor damaged by rodents or road debris.
