Hello,I'm having a problem with my 94 Corolla Dx and the problem is that the signal and break lights will not work. The problem started when my mom took out the CD player deck so she could install a new one thinking she was a car electronics expert. However she never did and I don't know what happened but the signal lights and brake lights will not work now. My dad tried changing the fuses in the black box under the hood on the right side and it will not work and he tried connecting some of the cables my mom disconnected.but the lights are still not working. I need the lights to work because I need to learn to drive the car because I go to college in 2 months. Anybody know what the problem could be and how to fix it so that I can finally get on the road and practice?
