My son wrecked his 2003 Ranger and we got it all back together and he's been driving it for a couple months now. I had replaced the air bags (pick-n-pull) but the dash light flashed a 19 code. I installed a used air bag control module (pick-n-pull) and it started flashing a 29 code, plus the headlights stopped working. I think the 29 means that the module is the wrong year, so I installed the old module and it flashes a 19 code again but the headlights still won't work. I checked all the fuses. Any help would be appreciated.
