One problem at a time. Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there. The AirBag light's a different story - Take the vehicle into a Hyundai Service Center (dealership), pay the diagnostic fee. They will tell you EXACTLY what the problem is and what's needed to fix it (parts, labor, tax, time-frame, etc.). Once you find out what the problem is, them maybe you can repair it yourself.

Check the park light fuse before you condemn the headlight switch. Does the dome light come on when door is opened? Can you use the dome light switch on the dash to turn it on and off as well?

Your head light got nothing to do with the other two problems.
As for the air condition and the dash you need to change the ignition switch $63.00 from autozone this should take care of other problem such as air bag light as will.by the way air bag recall for all 2000 3 series for air bag light now dealer will fix for free of charge.
Good luck.

1998 Ford Explorer beeping noise in right front dash why?


The Air Bag module will sound the tone generator if it is having a problem turning on the air bag light. Check for a burned out bulb, loss of power to the bulb from the fuse panel, or open circuit between the bulb and the air bag module. Try replacing the airbag light bulb.

Air Bag Light, Brake Light, & ABS Light came on in the dashboard.


Check and see if your alternator is charging
Low voltage will cause those lights to come on, as the computer is shutting down.

To check your alternator you will need a volt meter... WITH the engine running you should have about 14 volts coming out. IF NOT you need to replace the Alternator!

98 elantra will not start and headlights dont work


Check that the battery connections are tight and secure. If yes, check the starter motor connectors and check current to the starter while the ignition key is turned. If there is no current, try wiring the starter directly to the battery. If it turns, then the problem is in the wiring or it could be the starter motor fuse. If the starter does not turn, remove the starter and take it to an auto parts store for testing.
