I am having the same issue others are having with the instrument guages' needles pegging out, then going to zero then to normal when I get to around 40 mph. Just prior to this happening I feel what feels like an engine miss and the lights flicker. I did some research on here and other sites and found that several people associated this with the alternator. My 03 has 117,000 so I figured it must be the alternator going. So, I replaced that with no change. And now in addition to this with the ignition on, running or not, when I activate my left turn signal all of my dash light flicker in sync with the turn signal. Same thing when I turn on the hazards with and without the ignition on. All of my dash light flicker in sync with the hazards. Also when I have the ignition off and the key out, if I step on the brake pedal the instrument lights come on along with my parking lights and the chime goes off as if I left my lights on. Now I am thinking this must be an electrical issue. I checked battery connections, fuses, relays and have found everything to be working properly and secure. My Haynes manual shows an electronic flasher module in the wiring diagram that all of the above tie into but I cannot find this thing to test it. Does anyone know where this might be or have had this issue before? Sorry to be so long winded but wanted to be accurate. Any help would be greatly appreciated. Thanks.
