Hi!

I posted about this once and was given some advice....but I have another question and wanted to make sure it was seen.

My 2001 Hyundai Elantra is having a few electrical issues.

The first issue is that my power windows stopped working. The fuse is good. I was assuming that the issue was maybe with the main switch or something...and honestly even though it's annoying...nonworking windows are the least of my issues at the moment, so I didn't even give it a second thought until recently.

Now my headlights are burning out within days. I have been through three pairs in the last month. Currently, I have given up and am avoiding driving at night or using my high beams (only the low ones are burning out). Someone suggested it was a faulty alternator...but I'm being told that the alternator and battery are fine.

Now, I've also noticed that when I open my doors at night the interior lights aren't coming on.

I'm thinking there is some sort of underlying electrical problem with the car. Any ideas?

Thanks so much!

Amanda

I dont think there is an answer to this yet but Elantra suffer from burning out headlamp bulbs continuously. BUt 3 sets in a month is too much. Other then checking the connector for the head lamp and checking the ground circuit I dont know what else to say. You might have to get a dealer look at it. Atlteast they will gaurantee the work and if it solves the problem for longer then a month then you know they fixed it. Otherwise you have repair warranty and just have them fix it again.

I had similar problems (3 blown headlights in a month), but now have really slow wipers on my 02 Elantra. Any idea what's causing it?

did you clean your bulbs after you installed them any moisture in the housing?

Sorry to read of your "issues". It really sucks when multiple minor problems combine--it begins to become overwhelming.

Posting your location may help --perhaps someone here is close enough to take a look at your car.
I'm in Bel Air, MD--if that is of any help.

AS FAR AS YOUR POWER WINDOWS AND DOORS THE ELECTRICL CONNECTOR BETWEEN THE DRIVERS SIDE DOOR AND BODY MY BE CORRODING UP. MINE FRIED A FEW YEARS AGO AND HAD TO PATCH IT BACK TOGETHER. AS FAR AS THE LIGHTS GO ITS BEEN SUGGESTED THAT YOU CHANGE THEN BOTH AT THE SAME TIME? I HAVEN'T TRIED IT YET THOUGH.

This sounds like an alternator problem. The alternator will overcharge if its internal regulator has shorted and no longer grounds voltage above 14.8 volts. If this happens your alternator could push out more than 18volts to the battery. This could boil the battery and eventually cause it to explode.

An easy way to check for an overcharge is to connect a voltmeter to the battery terminals while the car is running. if it shows anything over 15 volts, there is a problem with the regulator.

If its between 13.8 and 14.8 and you are still experiencing these problems than turn your lights and heater on while the engine is idling and check the voltage again. if its too high replace the regulator. Sometimes the regulator only malfunctions when there is a higher load on the electrical system.

This is a common problem with Hyundai vehicles.

Did u check any positive cable. Some times a cable looses it protective cover and start hiting the metal(ground) that can cause thing to blow (like fuses and bulbs.)

I know this is kind of an old thread but I was having similiar problems on my 99 hyundai accent and it was indeed the alternator. While driving my blower would start getting faster and my wipers would go faster and my headlights would get bright and then go out. The alternator was sending a huge surge and just blowing the lights out.
