6G Celicas Forums

Hello I'm new to this great site, I recently bought a 94 celica , everything seems to run good, except i've been trying to figure out why my car when i don't have my key on ignition and i turn on my windshield wipers, my car will try to crank up, i don't even have my foot clutching, when i finally turn it over with my key, there's seem to be no electricity goin through my power windows, no radio, no sunroof, even my speed and rpm meters don't show any movement, I hope someone can help me with this, I've been reading the forums, i have come across maybe the 100a fuse might've blown I don't know I need some input I appreciate it and apologize for my grammar

just so I understand...

have you ever replaced that 100a fuse ? or looked at it to see if it was blown ? If it was blown you battery would die because the alternator wouldn't be charging. If it's loose/not secured that might be the problem. Do you know where that one is located ?

when you start the car normally does everything work nornally ?

my next guess would be you have a bad ground somewhere or *possibly* the voltage regulator in the alternator.

Have you or someone recently changed your alternator ?

Was there any electrical work done on the car recently ? (new stereo, alarm, ect..)

I just thought i could be the 100a fuse I havent look at it just yet, I supposed It can't be it cuz my car still starts and the battery doesnt seem to be dead, I don't know where it's located, maybe a pic will help, another thing is my car runs good but i can't seem to use my radio, can't roll down my windows, ac/heater don't blow air and even my rpm and speed gauges don't seem to work...I just bought the car, when i heard it start and the engine sounded strong, that's all it matters to me at the moment, but now I got this problem, You think it could be the ignition switch, I don't know why the wipers got anything to do with the ignition...

Sounds like the aux power is not goin hot.

turn your key up until just before it starts to crank. This should turn on your aux accessories (guages, int lights etc...) If nothing happens then it might be as simple as a blown fuse, or a short somewhere.

Either way... i would get it looked at soon. Just becasue the engine works and u can drive, doesnt mean its safe to drive. Elec problems can cause some major damage if left alone.

Hey guys bringing this back up but where would one look to see if their is a short for Aux accessories that would drain the battery if not found, i believe i have this similar issue as my battery went dead in a day, probably do to a short that controls aux accessories? pictures would help tons too.

The easiest way to do this would be to get a multimeter and use it to see if there is a significant load on the battery. There will always be minimal load though, for things like the clock and stereo memory.


Make sure the car is turned off and check for a load.
If there is a significant load, start pulling fuses 1 at a time. After you pull each fuse, check to see if the load is gone. once you find the culprit, the load should nearly dissappear.
This will at least narrow the drain down to a specific accessory and make finding the short a lot easier.

Hope this helps

take it to autozone, they will check battery and your alternator for free, just some advice...
