i have the same problem. instrument clsuter, dash board, HVAC panel and side door lights are all not coming on. Headlight, interior dome light and fog lights are all working. I have swapped the headlight switch with another and still no luck. One day I went on a bump and they all came on but at full intensity no matter what the dimmer switch is set to. Then couple days later they went off after going above another bump. The fuse keeps blowing off. when replaced they will come on, but as soon as you turn ignition off and then back on, fuse will blow again. I have an aftermarket radio and according to what I am reading online, that it might be the colprit. Please help.
