Hi all, Today I installing a graphic equalizer in my 2002 Silverado and once I was completed I went to power up and nothing. Most things are functioning all but my main issue is my stereo deck won't power up and oddly enough my odometer, RPM, and MPH gauges have quit functioning as well. The voltage, oil pressure, temperature, and fuel guages are all in working order. I've gone through all the fuses and relays to no success. Before I started the install I tested all the equipment just hanging out of the dash and everything functioned properly. I was hoping someone would have some advice. I've gone through everything I can think of and come up with nothing. AutoZone was kind enough to let me try different relays in hopes of finding it but no luck. I also tested the deck in another vehicle afterward and all is well. Any help or ideas would be great because I can't stand having my dashboard completely taken apart. Thanks!
