I need some seriously help. I plugged in my small trailer the other day and something happened to my 02 Ram 1500. The gauges, doorlocks, interior lights, wipers, & turn signals all stopped working. I checked all the fuses, including the high amperage ones, three times , but nothings blown. I then replaced the headlight switch because I've heard they can blow. Still nothing. I've checked all the connections, grounds, and harnesses for damage, but I've found nothing. I think it may be some sort of computer problem, but I'm not sure. The red security light in the instrument cluster stays on. Has anyone had a similar problem? I'm thinging maybe it's the BCM, but I'm not sure where to find it. Any help you guys could give I would really appreciate, it's just not right to have a RAM parked. Thanks - Reg
