I have read all the comments about dashboard lights, and have the same problem. I have a 1998 Mazda 626, and the dashboard and radio lights are out. All other lights work, along with radio itself, but when I turn the lights on the dashboard lights do not work, and the face of the radio goes dark. I originally thought this was caused when an aftermarket radio was installed, and the original wiring harness for the radio was cut.
I have since obtained a replacement radio wiring harness, and after installing it, the dash lights, nor the radio lights still don't work. There are 2 wires going into the radio harness, a red one, and a gray one, with 2 matching wires in the harness, 1 for illumination, and 1 for dimmer. I tried connecting the red wire to the illumination, and the gray one to the dimmer, and vice versa, but neither way worked.
I then made sure every fuse in the fuse box was ok, removing each one, and making sure they were not blown.
From what I see posted on this site, it looks like perhaps the dimmer switch or headlight switch is blown out. Is there a way for me to test the dimmer switch before I go and buy a replacement? There are 3 wires connected to the plug for the dimmer switch, 1 red, 1 gray, and 1 black. I assume the black is the ground, and then I have the 2 other wires with the same colors as those that go to the radio, 1 red, and 1 gray.
I also see mention of the headlight switch. Would this be the switch that turns on the headlights? Is there a way to test it?
Any suggestions would be appreciated?
have the same problem?
