The radiator has a dual fan system, when the air con goes its reading as hot and stays on. There is an electrical plug near the washer fluid basin on the fender on the right side, unplug it as it is the reset switch stuck open for the air con. This will not harm the engine and your regular radiator fan will still come on when hot.

Chevy Venture Van 2007 air bag light coming on dash board while driving

That means there is a fault in the airbag system. Every time you start the vehicle it will do a self check. If the self check fails the light will stay on.

You will need a higher end scan tool to pull codes from the airbag module. Once you know what codes are present you will have a better idea of what direction to head into.

Post the codes in the comments below and I'll do my best to help you figure it out.

Turn off airbag light

Air bag lights self reset you still have a existing problem during the self test it has detected a open/shorted circuit disabling the system. watch your air bag light then turn key on do not start engine lamp comes on then goes out and then comes back on again. this is the start up initialization of the system and sensor or wiring does not pass the system goes fail safe. with a scanner the air bag code can be read thru the OBDii connector if having hyundai body control software.

Service engine light on my Infinity 2001 QX4 4WD goes on and stays on usually for a couple of weeks then stays off for weeks, the code shows up as 420-430 which I think is catalytic converter, it's been...

The Service Engine Light means, time for an oil change and other regular maintainance items like engine air filter, check all other fluids, lube chassis, it's a reminder to take care of your car. When the maintainence is done, then you or whoever works on it resets the light, and it will come on again at the next proper interval. Every 3000 miles or 3 months whichever comes first is the standard.
Take good care of your car, it will cost you a bit, but your car will be happy and it will take good care of you. Neglect your car, it'll cost you much much more and you'll be sorry.
