Only brought on for Luciano Narsingh 11 minutes earlier, the Ghana international emerged hero for the Jack Army as his 77th minute equaliser ensured a 1-1 home stalemate at Liberty Stadium.
It was the 26-year-old's first league goal since August, the previous coincidentally coming against Palace in the first leg fixture.
“I’ve been waiting for that goal for some time now,” Jordan said, as reported by his club's official website.
“Every weekend, you want to score but you cannot control the situation.
“My two league goals have come against Palace. I hope I can build on this and, more importantly, help things change for the team.
“It was a good game from us. We tried to get the win, but the most important thing was that we didn’t lose.
“We need to get out of this situation and will fight very hard to do so.”
Swansea came into Saturday's game on the back of two successive defeats, with seven goals conceded in those matches.
After the Palace stalemate, however, Jordan believes things can only get better as they prepare to face Liverpool on Boxing Day.
“We all have a job to do. I think we responded well,” he added.
“We will take it day by day and see what happens in the future.
“We will do our best to get something out of the game against Liverpool.
"We will build step by step and, hopefully, things will get better. It is important for us to get a good result."
So far this season, Jordan has made 19 league appearances involving 16 starts and two goals for Swansea, who dangerously sit bottom of the table.
