Windows don't dip, Alarm chirps twice and randomly alarms when locked
Problem statement. My windows don't dip when I unlock the convertable roof. I've already replaced the micro-switch, and the roof control unit in the footwell after this unit burnt out.
The windows also don't dip when the roof is down and I raise the roof. Finally, the alarm acts erratically -- it chirps twice when I lock (it locks), but then if often starts to alarm for no reason. The windows do go up though when I latch the roof after raising it. Background: I had the alarm, keys and ECU reprogrammed a couple of years ago, and had no issues. The roof stopped working last year, which I fixed, ultimately replacing the microswitch in addition to the other parts shown in the thread -- although this issue described above has lingered. Current fault codes: Alarm I48 - 34: Status: Not present. Passenger compartment monitoring sensor, short to ground. Occurrence counter 1 - 33: Status: Not present. W line (DME - immobilizer), open circuit. Occurrence counter 74 - 25: Status lead, signal converter, short circuit to B+. Occurrence counter 127 Alarm I32 - 34: Status: Not present. Interior sensor faulty, Not present. Occurrence counter 1 - 33: Status: Not present. Interior sensor faulty, Not present. Occurrence counter 74 - 25: W lead, status - present. Occurrence counter 127 I just pulled out the panel where the roof latches, and confirmed that all 3 connectors were firmly seated. Any thoughts or suggestions? I guess I'll go through the troubleshooting the relay controller again. -John

Are there any fault codes on the window controller? If so clear them.
Also please post the make/model/year. |
