QuestionQUESTION: if it are the fuses that are blown..which fuses am i looking for...for these lights?
ANSWER: Hi, Helgi. I'll need a little more information to be of assistance. First, I'll need to know the year of your Sonata so I can pull up the correct schematic. Also, I'd like to the following information:
1. What is the issue with these lamps? Do they stay on? Do they refuse to come on during bulb check or display some other symptom that they're not operating correctly? Please elaborate.
2. I'm not familiar with a "power lamp." Please try to describe the icon or writing that appears when this lamp is illuminated, including the color of the lamp. Also, please let me know whether this is a U.S. spec vehicle. I suspect this may be a lamp that is present on some vehicles but not U.S. vehicles. If not a U.S. spec vehicle, please, if you can, tell me what your owner's manual says this lamp indicates.

QUESTION: hi again. it is a 1994 sonata cls with the 2.0 L engine. I live in Iceland so it is probably made for European market.
The problem with the lamps is that they do not work, when the car is low on fuel, the low fuel lamp doesn't illuminate, and the power lamp is between the low gas light and the open door light, it should come on if you press the esc button in front of the gear lever
AnswerI'm presuming your vehicle is similar to the 1995 Sonata sold in the U.S. There's a picture here: http://en.wikipedia.org/wiki/Image:2nd-Sonata.jpg
The "power" lamp you describe had a position in the U.S. instrument cluster, but there was never a circuit that went to it. If I recall correctly, it actually displayed "PWR," but I cannot recall for certain.
The low fuel lamp definitely has no dedicated fuse. If the fuse were the issue, then many of the other indicator lamps would be out as well. From what I can ascertain from the transmission schematic, the power lamp also has no dedicated fuse. If the fuse that supplies power to the power lamp blew, you'd have many transmission related problems.
The most likely issue with your low fuel lamp is either that your fuel level isn't low enough or the thermistor in the tank isn't working properly. You can test the circuit and lamp by grounding the yellow/red wire at the fuel sender in the rear of the fuel tank. If the lamp illuminates, then you've just verified the lamp and wiring are okay. In fact, if this is the case, it's reasonably likely that the issue is that the sender and gauge were probably calibrated incorrectly from the factory. There's a technical service bulletin (TSB) for U.S. models regarding this issue. The solution is to install a shunt harness (part number 00300-B5100) between the vehicle harness and the sender.
You can view this TSB at www.hmaservice.com. You'll need to register for a free account, and the site requires Internet Explorer. Once you've logged in, go to the TSB section and enter 1995 Sonata as your model and year. Then view TSB 95-90-006.
Your ESC switch works by switching power on and off. In the "power" position, power is supplied along the white/black wire to the transmission control module (TCM) and the instrument cluster. The switch is probably the easiest place to begin diagnosis. Pull up the shifter plate and make sure the switch is plugged in. If so, use a test lamp to verify the switch applies power to the black/white wire when moved to the "power" position.
