How can I reset the drive side air bag light?

Yes you can't drive it with the seat out. The air bag light will stay on and the air bags will be inoperative. Once you reinstall the seat everything should go back to normal.

what do you mean reset, if the air bag light is on, there will be a fault code set to address the problem. Have a technician check and make necessary repair.

I assume you are counting the air bag light flash, If so light flash 19 is for an drivers side air bag circuit,problem which could be low resistance,circuit open ,short to voltage short to ground. and cannot be cleared or reset until the concern is corrected.ford motor vehicles air bag light will go out when concern is no longer present but will remain in memory, I would start by inspecting wiring under dash going up to steering wheel ,the air bag connector is located just to right of steering column when sitting in the drivers seat after removing the trim panel below the steering column and is a yellow connector, Please use caution when connecting or disconnecting any connectors to air bag system ,battery should be disconnected for min of ten min's prior to attempting any work on air bag curcuits. I have seen many problems in the past with the air bag itself also with the clock spring ,question does the horn,cruise control and steering wheel controls for audio system (IF SO EQuIPPED) work properly? if not there is very possibly a clock spring problem

u dont as tneubauer and emissionwis state dangerous to be fooling around with airbag system if light on have vehicle scanned some auto store such as auto zone / advanced auto scan for free the code can give u a place to start -but unless ur a tech who has dealt with air bags dont mess around with connections or even dash -bring to auto tech or dealer for repairs-- with light on driving can be hazardous because bag or bags can deploy

The side impact air bag in the door? Unhook the battery. Wait 5 minutes, then unbolt it and unplug it. It will be fine. Don't hook up the battery with the air bag unplugged to test the window, it will set a trouble code and the air bag light will be on until you go to the dealer and have it reset. Just make sure before you hook the battery back up the airbag is bolted back in place and plugged in.

Get what is wrong fixed and it will go off.

There are no campaigns/recalls for the SRS (Supplemental Restraint System - Air Bag). However, there is a Service Bulleting regarding the wiring harness under the seats:
DESCRIPTION: Motion of the side impact air bag wiring harness and connector may result in illumination of the air bag warning light and one or both diagnostic codes listed below:

• B1378: Driver side air bag (DSAB) resistance high.
• B1382: Passenger side air bag (PSAB) resistance high.

This campaign provides a new side impact air bag wiring harness connector mounting procedure. VEHICLES AFFECTED:

• Model : 1999 - 2002 SONATA vehicles
• Production date range: - Produced through July 23, 2001
  
• VIN range: - Produced through KMHWF35H82A526636
  

SPECIAL NOTES: The service procedure to be followed depends on the original wire harness routing under the seats. The required parts are different for each procedure.

• For vehicles produced on or before June 30, 1999, use the procedure for Type 1 seats. Order service kit part number 88010-38A00.
• For vehicles produced on or after July 1, 1999, use the procedure for Type 2 seats. Order service kit part number 88010-38B00.

If your vehicle doesn't fall within the production range, it's not affected.
I recommend you take the vehicle into a Hyundai Service Department and ask them if your vehicle has had this repair already. If it doesn't apply, pay the diagnostic fee to find out what the problem is. They will give you an estimate of repairs (parts, labor, tax, time-frame, etc.).. Then you'll know what the problem is.
