Multiple issues, passenger window is a very common issue, looked on YouTube and found many videos for it was able to jump with direct power to the pigtail using wires and a battery and was able to roll it up but no explanation for why it ends up having this issue, heater core also a consistent issue, it is obvious with passenger side gs cold and 95% of the fix is a new heater core. Headrests popping, had the safety recall done 02chz28 (Recall S61) and never was mentioned or brought up by local dealer, both seatbelts are not functioning properly, passenger side is the worst, locks up and both are running along the plastic causing it to become deformed and wearing on the edges of the belts. Vehicle has obvious replacements on the front but no accident history. Hood is a different vin number and grill is not original from factory. I found the original photo of the car’s first sale post. Odd malfunction is washer fluid can run out with no indicator being triggered for low fluid.
