Hello all. 1995 XJS Convertible. Out in very heavy rain last evening. Since A/C has been non operative past 2 years, ran heater/defroster to clean windshield. Frequently opened driver's door window to release heat (and let in rain). Then the window was lowered, and will not come up. No sound, nothing. Passenger door window works perfectly. Removed inner door covering. Located connector with 10 wires. Assume wires are for power seats, seat heater, seat memory, and window up/down. Wiring diagram says UY and OY, which I recall is Blue/Yellow, and Orange/Yellow. Question. How can I test - troubleshoot - repair? All suggestions are appreciated.
