2003 Hundia Sante fe Altornator?

Sounds like the alternator is bad. You can take it to Advanced Auto Parts or Autozone, and they will test both the alternator and battery for FREE. If the battery was bad, the car usually won't turn off once started because the car will be running off the alternator. Not to say I havn't seen a battery do that, but it is rare. To me it is the alternator. Plus, Autozone or Advance Auto will have your alternator in stock.

The OEM tire is the Goodrich Dueller HT but these basically ****. I just bought Yokohama AVid Tire for my 2003 Hyundai Santa Fe. They are excellent. Great on the road and very good in snow. I used Tire Rack.com and was very pleased with their selection. Great site to find tires.

your santa fe is in 4wd all the time.

the heater blower switch is bad is loose. Get a replacement and I am sure it will work fine for you

Hope you changed plugs as well
When you had problem with coil,plugs will get damaged,and will malfuntion

You have not responded CLEARLY!... which ENGINE?

Under the wipers is a plastic shield which keeps dirt out. REmove cover & you will see an air filter usually on the passenger side replace it.

why would you fix a problem that is not there.if it is fine then enjoy it.plugleads only get changed if faulty.

put it on 12 volt setting 2amp

sounds like you need a transmission, with those incorrect gear ratio codes
