Top 20 Hyundai Motor 2002 Sonata Questions & Answers

Question edited for clarity. Question moved to model category from Washing Machines! Is the car running okay? If it is, don't worry. Makers make wiring harnesses for all variations of a model and the often have spare connectors with no mating connector for it. It is impossible to identify what they are, or were unless you have a factory wiring diagram for that specific vehicle. It it worries you, the dealership would know. ..

Most likely warped rotors. See this post http://ricksfreeautorepairadvice.com/warped-rotors-and-brake-pulsation

A clogged cabin air filter can cause repeat resistor failures. A bad blower fan can also cause repeat resistor failure. http://ricksfreeautorepairadvice.com/blower-only-works-on-high-speed/

replace the climate control module

Check oil level.

There is no such module, the fan is controlled through the central engine Powertrain control module.

Don't assume that a new battery is ok. Personally, I've fitted a new battery to later discover that it was that new battery at fault. However, it's quite rare .. If your battery is discharging very quickly irrespective of whether the engine is running or the car is parked - suspect the alternator. Inside the alternator there is a rectifier pack - diodes - if this fails it can allow your battery to discharge very quickly - sometimes within a minute or two, quite literally. If you can, disconnect the leads from the back of your alternator and charge your battery. Reconnect the battery but not the alternator. If your car starts and continues to start without the battery going flat - your alternator is at fault. The only other fault that can cause a healthy battery to discharge is a parasitic drain - something is remaining 'live' after the engine is switched off and draining your battery power. If you drive your car to a spares shop/auto electrician they will be able to tell you within a minute if your alternator is the problem.

Is it in backwards?

Huyndai's are netorious for transmissions doing funny things if the Throttle Possition Sensor is bad. Not an expensive part that you could probably change yourself. It is an inexpensive try, if it does not remedy the situation. Also, the computers regulate shift patterns. You might unhook the battery and leave it unhooked for 30 min. or so, and see if it will re-learn shift points.

raise and support the rear of vehicle, then disconnect all fuel, vacuum lines, electrical wires that go to the fuel tank. disconnect the fuel filler neck from gas tank, support the fuel tank with a jack, disconnect the fuel tank support straps and lower tank looking for anything that you may have overlooked to disconnect.

somethings wrong w the module that controls that area--a shop manual can xplain it-library has them-or bring it to a private shop w some experience

You have a bad ground. Most are behind the side kick panels.

Only Ford products use a cutoff switch for the fuel system.

Do you have electronic door locks? If so, check your fuses-simplest place to start. Next I would take the lock out on the inside, it could be a bad ground wire. Good Luck.

Having had this problem (a couple of times on our 2002 Hyundai Sonata GLS V6) my first guess is, its probably the starter. So although there are other possibilities, I would be surprised if it's not. The first time I replaced it with a used starter from a salvage store. That turned out to be a mistake because I had to replace that one within a year. Replacing the starter isn't too hard, depending on your mechanical skill level. The quick sequence is; disconnect the battery. Remove electrical connections from starter. Remove mounting bolts (3 I think). Maneuver the starter down and out (this is a little tricky). If you choose to do this and need more detailed info let me know. I would also suggest you get one that carries a limited lifetime warranty because our Sonata may actually be on its fourth starter (I'd have to look at the records). Good luck.

Your original keys had a computer chip in them that is programed to your car's computer and you will have to have a dealership reprogram your new keys to match your car's computer. or if you still have the original ignition lock you can reinstall it and contact your local dealership and give them your car's Vin# which is located on title or vehicle registration. And most dealerships can make you a new ignition key. Then your car should sta
