Hi, i have an 1996 toyota corolla, i bought a new stereo, a jvc, and a wirering harness to be able to hook it up, i hooked everything up correctly, and it wouldnt power on, so i thought, maybe it isnt getting power, so i took a multi tester and sure enough it is getting 11-13 volts, enought for the radio, so i put in in my friends car and it works fine, so i decide to try my old factory radio, and now that doesnt work anymore either, neither do my clock and dome lights, so now it sounds like a blown fuse right, well i took out all of them and they looked fine, and i ohmes resistance tested them and they check out fine. so know not only do i not have a working radio, i dont have a clock a dome lights.....any ideas?
Hi, I did the same thing installing a CD deck into my 1996 Corolla but it Killed my CD deck ( burnd the Amp chip). I had so much bad luck with this car no more upgrades. But to solve your problem with the Clock not working is check the fuse in the Engine for "Dome 20A" that should Fix dome light, Buzzer,Clock, memory for the radio. I'm now going to put back the factory deck and leave it.
I hope this help.

the tail light issue could be just bad bulbs, check them with a meter ,, also, check the sockets for power to each contact point,, normally if the brake lights and flashers are working, the tail lights should too,, as far as the dash lights have you installed an after market stereo? If so a common problem is a wrong wire got grounded,The harness from the car to the factory radio has a wire for the dash lights that shows up as ground with the light off. When the lights are on the wire is 12V+. Check to see if you connected the ground from the new stereo to this wire. The radio will work perfect but everytime you turn thr park light on the fuse will blow...and the radio will continue to work. There should be a ground wire in the harness as well, ensure you connect the ground from the new stereo to this wire. there is a 15 amp fuse that blows, check them with a meter rather than by sight
Toyota Corolla has been around long enough that many owners find
themselves needing to replace the factory stereo. Installing a new
stereo in the Toyota Corolla gives improved sound and updated
features. Swapping out the stereo in the Toyota Corolla takes basic
tools and less than an hour. This article covers models from 1990 to
the hood and remove the negative battery cable from the terminal.
Apply the parking brake and place the car
> Remove the trim from
around the stereo by prying with your fingers at one corner. Some
early models have two screws at the top of the trim piece to remove
first. Allow the trim to hang on the drivers side of the dash if
it's connected to the cigarette lighter.
> Locate and remove the
four screws holding the stereo in place. Pull the radio out of the
dash and disconnect the wires from the back of the head unit.
> Connect the wiring
harness adaptor to the original harness and let it hang from the
dash. Slide the new stereo into the Toyota radio mounting kit, which
is a thin metal cover and secure it per the manufacturer's
instructions. Most adaptors have screws to hold the stereo in place,
however some have clips, which engage automatically. >Plug the wiring harness
adaptor and antenna wire into the back of the new head unit and push
the entire assembly into the dash. Reconnect the negative battery
cable and turn the radio on.
> Ensure all of the stereo
controls and speakers are working. Secure the radio in the dash with
the original four screws and replace the trim.
I would get a stereo installation kit for your car from Auto Zone or a local car audio store. It will have the surround for the new stereo to fit where the old one was and a harness that you can wire the new stereo to and the harness will have a plug to match the stock radio plug.
which fuse did you check. verify the wiring to the radio than comes from the light switch to the radio. if all this worked before , then it has to be work that you have done. the only link from the light switch to the radio is for inst panel dimming. first disconnect that wire and ck fuse for tail lights. make sure there is power on both sides of the fuse, use a test light.
I took my car to halfords to have my stereo fitted (also bought stereo from Halfords). they basically had to taken everything out of the middle bit to get to the stereo (All the air vents and control switches etc). It took about an hour to do, but at least you know there is no quick way to steal the radio once it is in. I think it helped that I managed to get a guy that had once been a macanic so he knew what he was doing.
Hope this helps
If you have the stock radio, then you don't need an unlock code, to the best of my knowledge. Check here for valuable information on how to rip apart your dashboard to free the harness that holds the radio in place: http://www.net4free.org/Other/nshahzad/stereo.html
