Another Electrical Problem Please HELP!
 

OK i have an 03 tiburon, the other day it started killing the power to the radio and dash lights whenever i would touch my brakes or turn on the turn signals. Also my passenger window hasnt worked for months and just all of a sudden started to work. I looked in the fusebox and could not find anything but under the dash there is a flashing red light, and whenever i seem to have this problem if i kick the dash the radio comes back on. Any Ideas?

You need to take your car someplace for a charging system check, and an ODB II scan. I think Autozone does both for free. Don't drive too far, sounds like you're running off the battery.

jsinton- have you gotten any leads on this issue yet? my 06 Tibby has been having the same thing going on and I haven't been able to figure out what's causing it. I actually noticed a couple weeks ago that the factory installed clock kept resetting itself everytime I started the car. Of course I didn't think anything of it until I finally noticed all the dash lights would blink off as well- mine would happen when pushed the brake to shift into reverse or use the turn signals. So far the only possible causes I have gotten are a bad fuse or relay.. let's hope that all it is!

Another possiblility is the battery is going bad. Try charging or replacing the battery if it's more than 4 years old.

ok, i think im going to drop by Autozone tomorrow AM for a check. I mentioned it to a mechanic friend of mine and he suggested it may be a problem with a ground or wire connection. Does that sound logical?

The thing that makes the diagnosis so difficult is that its happening very sporadically. It starts and runs just fine, but i was leaving the grocery store today and my power locks wouldnt even work, i had to use the key to open the door and then suddenly the dash lit up!!

Btw, thanks for the extra bit about the battery. Im pretty sure its less than a yr old as I just bought the car 8 months ago and the dealer said they had replaced it... lets hope that was true!!

And the plot thickens....

Had the battery, alternator, and starter tested today- guess what.. they're all working perfectly!!

oh well, back to the drawing board...

Yeah, I am not sure it is the battery, i have been driving my car like this for 2 weeks or so, and have no problems at all starting the car.

Ok, well you must have a short someplace. Start taking out the relays and fuses, make sure the connectors are clean, and reseat them.

Hey if you could do me a favor. Tonight i looked under the dash of my car and there was a black box blinking red at me. I pulled it down and there are 2 wires that look like coaxial cables like you use for your cable TV. one of mine was loose, could you see if yours are loose also?

Hey do you know what that black box under the dash is for?

RE: Another Electrical Problem Please HELP!
 

hey there!

im thinking the black box is the BCM- someone in another Tibby forum told me that may be the cause of my issues... i tried to get to it just now but i cant seem to get the panel below the steering column off so i can get at the box... i see there are two screws on the bottom part but taking those out hasnt helped.. how did you remove yours?

RE: Another Electrical Problem Please HELP!
 

Here is a link to figure out how to remove the BCM...

This shows you how to fix a relay that is bad on the BCM. Apparently what i was talking about was not the BCM. If replacing this works please let me know, i am worried that when the radio is going out my brake lights are not working as well.

The flashing red light under the dash is usually an indicator that there is an aftermarket alarm system installed on the vehicle. I would check for that first and see if you see and poorly made splices into your wiring harness under the dash. That is what the problem with your radio is sounding like. As for the other problems I would check your ETACS/BCM fuse if thats ok. I know these Tibs have a good rep for the BCMs dieing.
