I began having trouble with my right front window not rolling down. Then head lights began to flash on and off. I disconnected the battery first negative then positive removed ecm and cleaned all pins on ecm and the socket it plugs into using electronic parts cleaner. I waited for the socket and pins to dry before replacing the ecm and reconnecting the power. Problem resolved itself for a while. Now all problems came back and the battery light came on. Replaced the battery and alternator. The problem went away for a week now all problems came back and vehicle is unable to be driven. I believe there is a problem with the ecm's made for this vehicle. There are many reports of people having the same issues and no recalls. I believe that the ecm is causing many problems since all 3 issues are controlled by the ecm unit.
Most times, when I try to turn on my headlamps at night they do not turn on when I turn the switch. It usually takes me anywhere from 10 to 20 turns to get the headlamps to turn on and sometimes they will come on only for a few seconds and then turn back off. Often, while I am in motion at night, the headlights will simply turn off for no apparent reason but I have noticed that it seems to happen more when the alternator or fans start or when I am at a low rpm and then I have to pull over and try to get the lights back on. I have also noticed that when the vehicle is parked and all switches are off, the lights will turn on and off randomly. I have tried to locate a fuse and/or relay several times but do not know where to find those. . . They are not in the fuse relay center under the hood. This problem only effects the headlamps, the tail lights, front marker lights, brake lights, and turn signals all work fine I have also found numerous posts on different websites complaining about the same exact problem.
