Ok so I have a 2000 grand Cherokee. I went to Install some responder lights (fire dept) and the had everything wired up and was going to pull my power from the power acc fuse 20amp I believe. Soldered the wires to the switch so on and so forth. When I put the switch in its respected hole everything started smoking. Pulled everything off in a panic and started looking to make sure I hadn't messed anything up. Now my radio, a/c controls, cig lighters or dome lights do not work. The board has power to it because the lights are coming on just not the display on the radio or a/c controls. Checked the fuses and the power to the fuse block... Nothing so I replaced the fuse block and bcm and still same issue. Please help!
