Oh yeah its an 03 tib gt. None of the fuses are blown, want to see if there is a fix before i pull the bcm

 

I have run into this, and I can offer a solution but i will urge u to never use that key fob again :/
I only know solution for manual.

To override all security, put your key in turn to on poisiton as if your starting the car but don't put foot on clutch.
hold there for 10-20 seconds. turn off, take out key, and u have overridden all security and can start car and all electrics should work.

 

Hey unfortunately this did not solve the light issue

The light problem actually started happening earlier but once i opened up the passenger door and the alarm did go off. I unplugged the alarm horn and had to bump start the car then got it home, looked up that solution and it worked cause the car started up again. However this did not solve the light issue

 

Anyone have info on this? Do these all run off the same relay? If so which relay is it the one on the BCM or a different one?

 

same problem its stressing me out.


Anyone figure out a solution?

 

I've got the same problem. I got an 05 and the turning signals, power windows, interior light, and speedometer light stopped working. I'm about to pull the alternator out and test it. Due to the battery constantly draining.

 

Hey, I got the same problem with my interior lights. Just replaced the BCM. All the lights that are working with dimmer does not work. Dimmer is okey, just tested that it is not getting power either.

Did you replace the alternator or did you get lights working somehow?

 

Did anyone in here ever got a solution to fix these electrical issues in the Hyundai Tiburon? I have an 07 with no brake lights, no turn signal, no radio, no lights, no dashboard and no working windows or locks.

 

A lot of those are powered through the "dealer fuse" which is under a yellow cap on the BCM/interior fuse panel under the dash on the drivers side.
Another issue can be the main BCM power plug in the center of the BCM. It tends to get loose over time and overheats which melts the plastic. A similar issue just came up here in the last couple days, the fix is cheap and easy.

 

Did you check the fuse again afterwards? I'm wondering if you have a short somewhere that's causing it to immediately blow again.

 

Yes i thought about it but the fuse is still good

 

IAM having same problem . I can't find a straight answer. As of now my power windows are down , no tail lights no cluster lights no hazards turn signals not even the clicking noise the fuses are not burnt I don't know where to go from here have a 03 Tiburon GT 6 speed

 

Have you checked the "dealer fuse" as mentioned before?
How are you checking fuses, looking is not enough at times.

Also check the main power wire going into the BCM. It's a single wire, side facing driver, just below the fuses. It can overheat and melt the connector. It also reduces power to the BCM.

 

I have the tester and yes I've checked the fuses and the wire that's below the fuses on the driver side they're all the way clicked in however not exactly sure how many wires are supposed to be going to that

 

The red wire with the black sleeve that has yellow tape on it is the main BCM power feed. It appears fine, although you can see a little discoloration due to heat. Not an issue until the plastic housing starts to melt.

And yes, multiple peeps with similar issue, and multiple ideas to resolve it, but no wrap-up on what worked.
We like when someone comes back and states what worked.

 

Thank you for at least clarifying them the difference between the wires.It seems like a lot of people aren't active on here any more. ..
I want a diagram but having trouble finding free ones

 

Video man don't quit your day job. .... I actually did test my fuses that one included. Problem still actively **** up my now- non active night life . Wish I could drive at night and go in places with out Lossing my stereo system. " Stockton California". 🤘🏻🥀

Hello sir, i have a 2002 Tiburon v6 i have the same issue, do you find a solution ?

Have you tried the various suggestions earlier in this thread?
If you find a fix, please come back and post what the fix was.
As you can see, many people with the same issue, lots of suggestions, no follow-up if they resolved it.

 

yes i had tried the various suggestions earlie rbut none of them work yet, the car turn on but no turn light, no windows, no light on odometer, I have order the NEC EP2-3N1ST to change it on the bcm, i hope this will fix the issue.

 

Hello, for me i have buy a bcm of the same car with the keys already pair and just change it and everything is now working, on this car the bcm is a big issues and very expensive to repair by professionnal (i try ) and very hard to find in a décent price. So maybe try to change it directly if you can, you will save a lot of money and time Sory for my english not my native language i try my best
