Narrative:

Aircraft was dispatched with cockpit side window heat (right) inoperative. No weather on the descent but descending through approx FL200 the side windows fogged up and developed a thin layer of frost on the inside. Despite repeated wiping it was not possible to see other traffic or the airport through the first officers side windows. Iah was conducting right traffic downwind and base to runway 27. After landing it was necessary to open the first officers sliding window during taxi to see the gate numbers off of the right side of the aircraft. The temperature at iah was 26C and the dewpoint was 24C. Crews should be aware that in humid conditions there may not be any useful visibility during approach; landing and taxi in from a cold soaked window with no window heat.
