If someone thinks they can help me, please take the time to read this. Thanks in advance.



When I got my car, it had an alarm on it that I was told wasn't working right. No big deal, I could just replace it. But I put it off (didn't want to spend the money) for a while.

Now, for about a month, the car has been doing all kinds of weird things. Sometimes when I start the car, the alarm goes off. Some times the foglights stay on whether you turn the knob all the way forward or not, rather than just the day-time running lights.

The biggest problem of all is that sometimes when I turn the car off and have the key in hand, the cd player, radar detector, clock, etc. all stay on, and the mustic still plays. I can take care of this by detaching the face on my deck and turning off the radar obviously. But the amp and clock stay on. However, it always holds a good charge, even if the car is left like that for 9 hours, which it is 5 days a week.

One day the car wouldn't start, and I jumped it. After that I didn't have the problem for about two weeks. Then I installed my amp. The car was turned off and when I plugged in the power wire into the amp the cd player and all of the other stuff came on. So I had that problem for about a week. Then I installed my new tail lights, and the car stopped doing it. Last night my sub stopped hitting (its blown) so when I disconnected the amp the car started doing it again. I changed out the fuse holder under the hood, and it stopped doing it.

It seems like every time I touch anything electrical in my car anywhere, it either starts or stops doing this to me. Its a real pain in the ass. Now my power switch for the door locks will only lock or unlock the doors when the car is not started. If the car is running, the switch is just dead.

I was told by a guy I know that my alarm was bad and was causing all of these electrical problems. I went to a place in town yesterday to see about an alarm and I had one priced out and was setting up an appointment for Wednesday to be installed. I told them what all the problems I was having and the guy went to the back to talk to the "head installer" and he decides he doesn't want to touch it because it could be very difficult to pinpoint what is wrong with it. He also said that no one in town will want to touch it.

Well, last night I find the black box where all of the wires are attached to the alarm. Why is this so complicated? Can't the people installing a new alarm just cut that out. That way, even though the wires are tied in to the headlights, taillights, windows, door locks, and whatever else, they'd be useless if they're not hooked into the main unit of the alarm.

I don't get it. Does anyone know what I can do? I didn't want to just start cutting wires and yanking out fuses because I don't know enough about what I'm doing and I'm afraid I would mess something up even worse.

but i'm almost sure it all has to do w/ the alarm, and my car just turned 61k so its just out of warranty. it would cost a fortune for them just to look at it, let alone rewire all of it. cry

they messed up your accessories/switch wire up and they probably tapped into the light switch too and they messed up there too thats why your accessories and lights sometimes turn on, just take out the alarm and trash it or disable it, unplug the main unit of the alarm and everything should be fine, just make sure any wires arent layin around you dont wanna cause a short grin the car should work fine without the main unit as its only basically a relay thumbsup

could the alarm be the single reason for all of the problems i'm having... (door locks, headlights, stereo, etc.)?

^^ yes the alarm is like a bunch of relays and it makes things turn on and off, it can cause blown fuses, and bunch of other electrical problems if its not installed right, just unplug it but dont cut any wires till you show us that pic thumbsup

The car was popping the brake and tail light fuses.

Replaced fuse, brake lights now work.

I was installing 2 low beam H7 LED bulbs, so may be some wires got crossed. Have gone though wirings for the front and tail lights, taped over a few exposed spots.. It's still popping the 10 A tail light fuse. I put in a 30A fuse to keep running.

Will check again.

Looks like your Body Control Module under the dash is damaged.

The OEM Celica tail/brake light is dual filament incandescent 7440.

I replaced them with a LED bulb in the original socket, bought from China via eBay. One is fine, one bulb's wire got hot and burned, melted the socket. It did not blow the fuse and worked well for a couple years. One license plate wire had cracks along 6 inch length.

Eventually I had a short somewhere, tail light fuse blew. A craigslist guy wanted $150 diagnostics then more for repairs. I did not want to spend that money, guessing the shorts are easy to find, went in trouble shooting, replacing the 7.5 A with a 30A so the bulbs stay on long enough for me to find the short, but it overheated, burned and melted the fuse panel, blew the Body Control Module which costs $1,100 at dealer. Most other light bulbs and body functions went kaput, only front head lights and power windows were working. I spent lots of time in many days trying to find and fix the problem to no avail, causing more serious damages. Damn stupid. I was able to buy an used BCM/Fuse panel in eBay for $70.

I suspected a branch of wire harness was shorting inside the hatch's channel, was about to cut wires, pull it out and check for shorts, finally I wised up that I had no tools, did not know how to remove the rear defrosters' terminals without breaking. I called my trusty mechanics, he referred me to a local chassis electrical guy. He said $95 to find and fix the short. He installed the new BCM, things started working again. He looked at the tail light wiring and took out all body plastic panels, found the tail light wire had insulation completely melted along the whole length and a burned out spot behind the panel at the left passenger side. The guy who installed the digital video camera took that panel out and could likely have pinched the wire against the chassis, but that wire is also in the middle of the harness, so who knows.

Repair guy found the tail light wire got hot enough to melt and burn off insulation all along its length. He also found the license plate bulb's insulation brittled, cracked and open in a length about 6 ", could only be caused by heat. This tiny LED bulb supposedly draws very little DC current. I cannot explain why it got so hot. He had to unbundle the wire harness and run a long replacement wire from the burn spot to the fuse box under the dash. He said he found lots of problems with LED bulbs. He repaired thousands cars and should better than I. He replaced all rear light bulbs with incandescent. I paid him $200 total for the extra work. This guy is good and honest, recommended.

Any bros has bette rundersatanding of this LED problem, would be interesting to know.
