well the other day i turned my car on and let it warm up and then out of no where my windshild wipers went on then my door went crazy then the car turned off.
i went to check the fuses and my radio back up fuse was burned i changed it .
the minute i pluged the batery it blew the fuse so i checked wires uplugged stuff but cant seem to find what the problem is.
can anyone help
Thanks

 

Don't do the classic fix that everyone seems to WANT to do and just keep putting a bigger fuse in until it stops blowing. The reason it does that is either on e of two things. 1) You have a loose ground so your fuse becomes the ground--therfore blowing it. 2) Their is high resistance in the circuit causing more amps than the fuse can handle to be sent to it. Number two is the more likely cause. Check your wiring. The less wire the electricity has to flow through, the more resistance you get in the circuit, therfore increasing amperage. Electricity is lazy--if you have a 20gauge wire for 15 amps of pressure and the wire gets correded or kinked it's gonna feel like a 25gauge wire, therfore causing electricity to just work harder to get to it's destiniation--ground--therfore increasing amperage.

 

well i found out that if i unplug a wire that leads to the engine harness it doesnt blow the fuse but when i plug in the stereo(with the wire that goes to the engine unpluged) it blows the radio back up fuse and also the little 10a fuse in back of the stereo . i tried looking like crazy still can find whats wrong.
also i can only unlock my my doors but when i press the button to lock it doesnt do nothing

 

I gotta know what wire that is in order to help you out a little more. Find out what the wire from the harness is and let me know, that woulod be a lot of help. As for your door locks--do you have a security system on it? Maybe the one the dealership put on for you?

 

i will try to get pictures of that wire . i have an alarm i got installed on itat a stereo shop. an everything was working well for more then 2 years until now

 

well today when i went to try and figure out whats causeing the short . i plugged the wire back on and it didnt blow the fuse so i tried starting it and it will crank but not start. and also i could only lock my doors but not unlock them . and when as soon as i try plugging in the the radio it blows the 10A fuse on the radio it self.

 

can anyone help please
