The abandoned result means the Proteas cannot win the series with the home team 2-1 ahead with one game left to play on Friday on Ahmedabad.
India won the first T20I of the five-match series by a comprehensive margin of 101 runs in Cuttack before the tourists hit back with a 51-run victory in Mohali.
The hosts then retook the lead in the series with a seven-wicket win in Dharamsala after the Proteas were bowled out for just 117.
The visitors have opted to chop and change their line-up in all three completed games to test combinations ahead of the T20 World Cup early next year.
