    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 hyundaihouseofpower.com or newtiburon.com 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.

Parking lights stuck on


the park lamp relay is stuck on. its bad or the control to it is bad.
hazards next.
ok HAZ does glow park to park is a red herring.
the HAZ relay is stuck on, or controls to it are bad
the BCM 100% controls hazard at all times
the BCM gets and input from you , that you want HAZ and then closes the relay/
the HAZ switch ground pin 18 on the BCM, it not 12v here the switch is bad.
IF NOT< bad switch input the HAZ relay is bad.

Dash Fuse Box , fuse 7 is haz. and the relay is there.
replace the relay or the switch,
if you unplug the relay the haz will die.
i bench test relays and am not , doing that here.

I have a 99 Pontiac Sunfire, 2.2L and my turn signals quit working. I replaced the combination switch and the flasher/hazard relay, and still no joy. The problem was intermittent, and now it's just dead....


It will turn on when I hit the button and the turn signals do work. All of this has led to my ABS lights to come on as well. ??????????? Your best bet , take it to a qualified repair shop or learn to do better explanation's ! Or lean to do automotive electrical testing .

Under system click on lighting ,then under subsystem click on turn signals . Click the search button then the blue links .Check power an ground circuits ! This is how we diagnose electrical faults , not just replacing parts .

Turn Lamps
Voltage is applied through the TURN fuse and the turn/hazard flasher when the ignition switch is in the following positions:
• RUN
• BULB TEST
• START
The voltage travels to the contact in the hazard switch. The hazard switch is located in the turn/hazard-headlamp switch assembly. This contact is normally closed.
When the left turn signal is turned on, voltage is applied to the following components.
• The left turn indicator
• The left front park/turn lamp circuit 14
• The left rear turn lamp circuit 18
The turn lamps turn on immediately. The current flow heats up the timing element. The timing element is located in the turn/hazard flasher. The timing element repeatedly opens and closes the circuit. This action causes the turn lamps to begin flashing.
The voltage that is applied to the left front park/turn lamp is also applied to the left front marker lamp. If the headlamp switch is in the OFF position, the left front marker lamp will find a path to ground through one of the following lamps. The following lamps provide low resistance paths to ground:
• The right front marker lamp
• The right turn indicator
• The right front park/turn lamps
• The left front park/turn lamps
The left front marker lamp flashes with the turn lamps. The voltage drop across the marker lamp is much higher than the voltage drop across the other lamps. The lamps that are used for the ground path will not flash.
When the headlamp switch is in either the PARK or HEAD positions, voltage is applied through the following components:
• The EXT LP fuse
• The marker lamps
• The park lamps
When the left turn signal is turned on, the left marker lamp will have voltage at both connections. The left marker lamp does not light. When the turn/hazard flasher stops the voltage to the turn lamps, the marker lamp is grounded through the turn lamp. The marker lamp does not go on. The left front marker lamp flashes in the following manner:
• The left front marker lamp flashes on when the turn filament of the left front park/turn lamp goes off.
• The left front marker lamp flashes off when the turn filament of the left front park/turn lamp goes on.
Voltage is applied to the right lamps in the same manner, when the right turn signal is turned on.
Hazard Lamps
Voltage is applied at all times through the following components to the normally open contact of the hazard switch in the turn/hazard-headlamp switch assembly:
• The STOP HAZ fuse
• The turn/hazard flasher
When the hazard switch is turned on, voltage is applied to the following components:
• The front turn lamps
• The rear turn lamps
The following lamps flash on and off:
• All of the turn lamps
• Both of the turn indicators
The front marker lamps flash with the hazard lamps on, just as the front marker lamps flash when the turn lamps are on. If the headlamp switch is in the OFF position, the front marker lamps flash on when the hazard lamps are on. The front marker lights will flash on when the hazard lamps are on if the headlamp switch is in one of the following positions:
• PARK
• HEAD
When the hazard lamps are on, the following conditions apply:
• The turn circuit is always open.
• The turn/hazard flasher controls the lamp.
Park/Marker Lamps
Voltage is applied through the EXT LP fuse, to the headlamp switch at all times. Voltage is applied to the park lamps and the marker lamps when the headlamp switch is in the following positions:
• PARK
• HEAD
The front marker lamps are grounded through the turn filament of the respective front park/turn lamp. The front marker lamps light as a result.
Stop Lamps
Voltage is applied through the STOP HAZ fuse to the brake switch at all times. When the brake pedal is depressed, the brake switch closes. This action applies voltage through the turn/hazard-headlamp switch assembly to the following lamps:
• The high mounted stop lamp assembly
• The left tail/stop-turn lamps
• The right tail/stop-turn lamps

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.

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.
