Air bag light blinks a code 13 continuously, It doesn't come on and stay on it blinks 1---1-1-1......1---1-1-1.....etc. I have change the two sensors in the front, checked fuses(no fuses with a direct link to airbags) and don't know what else to check.

the code shown is indicate the following possibility

1- Faulty Assist Air Bag Module
2-Assist Air Bag Module harness is open or shorted
3- Assist Air Bag Module circuit poor electrical connection Faulty Diagnosis Sensor Unit

Please check and insure that all cable you have remove is fixed back correctly.

Code 13 for ford has it as: air bag sensor or crash sensor problem. May need to take to dealership for fix.

TROUBLE CODE CLEARING

1. Follow the diagnostic procedures to service the fault condition flashing on the air bag indicator prior to code clearing.

2. Cycle the ignition switch to OFF and then to RUN.

3. Observe air bag indicator prove-out (six ? two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.

4. Locate the Diagnostic "Trouble Code Clear" Connector (grey connector). located underneath the glove compartment, left side (06010) containing Circuits 631 (T/R) and 57 (BK).

5. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.

6. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).

7. Release short on Circuit 631 (T/R) to Circuit 57 (BK). This short must be released within 25 seconds after the diagnostic monitor tone sounds.

Diagnostic trouble code is now cleared from memory. Next highest priority diagnostic trouble code stored (if one exists) will begin flashing.

The codes and clearing proceedure above are to be used as a guide, NO claims are implied as to the correctness or accuracy of either.

This is a code 46 LH Crash Sensor - Not Mounted to Vehicle Properly. Often there is a poor contact on one of the wiring connectors. Some of the problems can happen from a poor connection where everything connects under the drivers side seat.
Here is a list of codes for the airbag light issues.

Hope this helps...

I was unable to locate code 31 in my book here is a copy of the codes. looks like you just need a fuse for #51. this may fix 31 as well.

the flashing is a code, you need to get a pen and a piece of paper and decode this. It is a two digit number the first set of flashes is the first number so lets say it flashes 3 times and then pauses for 3 to 5 seconds your first number would be 3 and then after the pause it blinks 4 times that would be your second number... so your code would be 34. anyways here is a list of the code meanings so after you count the two set of flashes and get your code compare it here

12=Low Battery Voltage
13=Air Bag Circuit Shorted to Ground
14=Primary Crash Sensor Circuit Shorted to Ground
21=Safing Sensor Not Mounted to Vehicle Properly
22=Safing Sensor Output Shorted to Battery Voltage
23=Safing Sensor Circuit Input Feed/Return Circuit Open
24=Safing Sensor Output Feed/Return Circuit Open

Seems to be a very common problem with Ford. The wiring harness beneath the drivers seat contains the sensors for the airbag system. Go under the drivers seat and secure all the wires and clips. This makes most error lights for the airbags go away. Hope this helps and good luck!

You can disconnect the battery for a few minutes. This will reset the computer. Re-connect the battery.
If the problem continues, you should call up auto parts stores to find one that has the meter for error code read-out. Get the code to find the problem. The read-out is free. Try Advance Auto, AutoZone etc.

Yes, it's called a lamp fault code.

9 is not familiar to me. Call dealer service department and ask them what code means.

Here are codes for a 94 Aerostar. I don't have 91 Sable. Sorry.
