Speedometer senser is jumping erraticaly
I had an Audi doing exactly the same. What happened was that through time, especially if the vehicle gets older with a higher milage, dust and dirt gets into the speedometer itself and causes all the small gears to get sticky. I opened it and lubricated all the small moving parts inside and all were ok. Try it before buying a new speedometer. (I'm talking about the speedometer clock itself) Hope this info might help.

Why won't it start?
If it starts and runs, it not the security. Check fuses first, then replace the starter.
Is the 2002 hyaundai santefe a zero tolerance motor
The 2002 Santa Fe 4 cyl and 6 cyl engines are deemed "Interference" engines. If the timing belt should break or slip a few teeth, the pistons will strike the valves and most likely destroy the engine. Thus it is very important to change the timing belt every 80,000 - 100,000 miles (along with a replacement water pump). I recommend buying a belt/pump kit and having a local independent shop do the install (much cheaper than a dealer's $600 charge!).
Belt & pump kits are available via Amazon:

Starting in 207 Hyundai started shifting all of their engines to metal timing "chains"... more or less eliminating the possibility of such a problem. However, water pumps still go out... but not nearly as often or catastrophic a problem!

Not easy to change, Location, since DIYer and you will want one next time Repair manual from an auto parts store. Easy to refer to in the middle of repair.
Fan for radiador dont work only wend a/c is turn on fans come on but slow i gat a hyundai santa fe 2002
In general, vehicles with electric radiator fans use an electronic temperature control so the fans only run as fast as needed. The energy to drive the fans come from the fuel you burn, so this is supposed to improve fuel economy. The air conditioner load makes the engine run hotter, so the fans should come on then.
Now, here is the real question: is the engine overheating at traffic light stops? Do you see an abnormal temperature rise on the dashboard gauge (assuming you have one)? If so, you may have a problem with the fan motor bearing, check for smooth and easy rotation of the fan when the engine is cold (it's dangerous to do so when the engine hot; the fan may come on even with the engine turned off). On the other hand, if the temperature indication is generally lower than it used to be, the temperature sensor may be going bad and is not calling for the fan to be on when it should be.
