Charlie Adam's ninth league goal of the season secured a point for Blackpool at a bitterly cold Cardiff City Stadium.
Ian Holloway's side had to come from behind after Mark Hudson gave Cardiff a ninth minute lead, heading home Peter Whittingham's free kick.
The Bluebirds also hit the bar through youngster Josh Magennis who later went off with a suspected broken leg.
Adam levelled for Blackpool 28 seconds after the restart firing low into the bottom corner.
The game could have gone either way as the promotion rivals looked to keep up the pressure on the top two.
Cardiff remain fourth in the Championship, while Blackpool climb up a place to seventh, just one position and two points off the play-offs.
Cardiff manager Dave Jones:
"Supporters are entitled to boo and cheer but I've said before that I don't understand booing your own players.
"We've played a team who's up there and we seem to think we have this divine right.
"We've got three or four lads in their throwing up and they could have easily come off.
"I'm proud of them today because they've dug in and that's hard going."
Blackpool manager Ian Holloway:
"I am pleased Cardiff did so well to get the game on but it didn't look as though we had turned up in the first half," he admitted.
"I had a go at my players during half-time and the second half was totally different as we forced their keeper to make a number of saves. The longer it went on the more we looked like going on to win.
"I cannot understand the crowd jeering Cardiff off the field when they are fourth in the league. They should have a reality check."
