Question about 1998 Hyundai Tiburon

1 Answer

When i drive my car until it warms up, all my electricals will start turning off. All my lights like my clock and dash lights all go dimmer. and eventually my turning signals wont work, but even though all this is happening the car still runs, but at a slower rate. Whenever i turn my headlights on all my lights will go dimmer than they already are and my RPM hand will freak out and read everything. Then when i turn the car off, the whole thing is dead. All the fuses are OK and i just rebuilt the alternator. i have a 1998 Hyundai Tiburon

Have the electrical system properly diagnosed. I suspect you have a poor ground connection between the alternator/battery & the chassis (OR - the alternator is failing).

The mile omiter and clock dont show up on the dash board on my Mercedes ML320


If nothing is broken, check to see your dash light dimmer isn't turned all the way down. If you have automatic lights that turn on at dusk and you place something over the light sensor (usually on the dash board), the headlights will come on during the day and set the dash lights to the dimmer switch setting.

When my headlights come on at night, the dash lights will not come on and the radio illumination behind the clock goes out. Why is this?


Check the dimmer switch to your dash light. If there turned down, your dash and radio illumination light will be dime or not working at all. Keep me posted, be glad to know if it is the dimmer switch turned down or you dimmer switch has gone bad. Good luck

My dashboard light does not come up.


Hi,
I'm assuming you mean the backlighting that illuminates the dials and clocks?
If so, do all the other lights, such as on the heater panel, and window switches work?
If so it's just a problem with the instrument panel.
Have you tried operating the dashlight dimmer switch? Sometimes if it's left in the same position for a long time the connection gets a bit dirty (like a crackly volume control on a stereo)
So it might be an idea to work it back and forth to see what happens.
Did this happen suddenly? That may indicate a bad connection to the dash unit.
Give the dash a slap above the clock units (you never know, it's worked for me)
It doesn't sound like a serious problem
The bulbs in the dash do gradually "blacken up" and do have to be changed periodically.
But you don't notice until the last one has gone
Please check for ANY other electrical items not working first.
Electricity can do some strange things in cars.
Hope I've been of some help.
Kev.

The lights on the instrument panels as well as the radio flash at intermittent intervals. There seems to be no rhyme or reason as to when this happens (i.e. hot or cold car, bumps or no bumps, turns or no...


I had intermittent instrument light problem that went dark for months, until today. :o) I read somewhere that it could be the dimmer switch and didn't think that was my problem as the dimmer worked (dimmed the radio and transmission indicator light) and playing with it never seemed to help with the problem. I did find it odd that dimmer was not completely linear, as it would get brighter up to a certain point and get slightly dimmer with the last little bit of travel.

Today, I took the instrument cluster apart to fix a broken clock, sticking gas & voltage gauges, and to explore the instrument light problem. I took apart the dimmer switch, and to my surprise (was expecting a simple POT), it was a very complicated PCB with some IC's, resistors, transistors, etc. I thought, "all this just to dim the light???" Anyway, I found the POT (potentiometer) and gave a few squirts of WD-40 and found it turning smoother. After putting it back together, the instrument light came back and the dimmer is now perfectly linear. Apparently, less than perfect POT causes some sort of funny logic through the network of IC's and transistors and can cause the instrument light to go on or off randomly at certain intervals.

Anyway, I'm so happy to have the light back along with a working clock and not having to punch the instrument cluster to see how much fuel I have. Not really a posting type, but wanted to help someone else out there with a similar problem with same cause.
