    i have a 03 tiburon and my passenger side turn signal is stuck on, it does not blink when turn signal is turned on just stays lit solid, does not shut off when car is turned off. Dash lights also do not shut off when car is turned off. I have to disconnect my battery to turn both of these things off. Any suggestions? Any one else having these problems?

I had the same problem, well my right turb signal stayed on all the time and i had to pull the fuse. the BCM under your dash is bad. the BCM is where all your fuses are plugged into. you can find one online for about $700ish. go to or and they might help you. 03 tiburons have bad luck when it comes to the BCM. change it out and your problems will be solved.also look on ebay.

    My turn signal was stuck on back in 2005 and was very annoying. I took it in and, luckily, my warranty took care of it. I have had quite a few electrical problems with my '03 Tiburon and they happened early on. I've had to replace my passenger door window motor a couple times and my driver side motor is out right now. Half of my dash lights burned out (or so I think) about two years after I bought the car and both of my reverse lights went out at the same time. I need to check closer but know it's not a fuse. Maybe the back up switch needs to be changed? Surely they both wouldn't have burned out at the same exact time.

All exterior lights run through a body control module on the left side of the dash. Inside the body control module there is a relay that might be sticking. You might need to replace the body control module to fix the problem.

I've had my '03 Tib's BCM replaced 3 times now. If you have the chip-in-key factory security feature, you can't use a second-hand BCM because it's programmed to your specific key.

I'm not aware of any cases where the BCM caused the speakers to crackle, but the parking light thing definitely sounds like the BCM.

Right turn signal light stays on front and back and will not work. lights stay on when car is not running and is draining battery

this problem is a bad BCM the relay is part of the computer system and your problem is common. replace the BCM and reprogram security and you will be good to go.

Or find someone to replace the relays inside. Harder to do than you think, I change them all the ime, but not easy to find the replacements.

2003 Hyundai Tiburon GT 2.7 right turn signals always 'on'

In your Tiburon, the "fuse box panel" is called a BCM, or Body Control Module. It contains all kinds of ****, including a microprocessor.

Other than paying the dealer to replace the BCM, there really not much you can do to solve the problem. I've had my BCM replaced 3 times now. Y

You can just leave the hazard fuse out, but eventually the BCM will further fail, causing all kinds of electrical problems.

The tiburon turn signals are controlled by a bcm (body control module) The bcm controls the ground to the signals. These always go bad and cause the signal to stick on or just not work. hope i was a help.
