If your 2000 C4 Cabrio passenger window stopped working after a roof cycle, try this:
• Reset the window: Hold the switch up for 5-10 sec after fully raising it.
• Check wiring: Roof movement may have loosened or pinched a wire.
• Inspect fuses/relays: A fuse linked to the window or roof module may be blown.
• Scan for faults: Use a diagnostic tool to check for roof control module errors.
