Birmingham's Bowyer opened the scores at Ewood Park
Blackburn came back from behind to earn a share of the spoils against fellow strugglers Birmingham at Ewood Park.
Lee Bowyer put the visitors ahead with a header from Cameron Jerome's dinked pass across the face of goal.
But Junior Hoilett equalised in first-half injury time, stealing the ball off Liam Ridgewell and beating Ben Foster before calmly slotting into the corner.
Birmingham have now taken four points from two games while Blackburn made it three draws on the bounce.
The visitors arrived at Ewood Park without a win away at Blackburn since 1968 and that record still stands, but it was the fight for Premier League survival that took precedence in this match.
Level on points but only two points off the relegation zone ahead of the match, both managers had called on their players to give their all in this crucial encounter.
Blackburn manager Steve Kean, without a win in seven games, had dubbed the matches remaining in the season run-in as cup ties.
McLeish praises Birmingham character
Birmingham boss Alex McLeish, meanwhile, wanted his side to bare their teeth and win only their third of 20 away league games.
But it was a fairly toothless affair in the opening half hour, with the game most notable for a string of nervy misplaced passes and one early Chris Samba header for Blackburn.
All that changed when Blues took the lead though, Sebastian Larsson unleashing a teasing cross into the box which Jerome prodded across goal and Bowyer headed in.
There was a hint of offside about the 34-year-old's effort but the goal stood and the game finally took off.
With noise levels rising inside Ewood Park, Roque Santa Cruz almost grabbed an equaliser for Rovers but the 29-year-old forward could only head Hoilett's cross past the post.
Kean went on the offensive after injury forced off defender Ryan Nelsen, the manager throwing on striker Jason Roberts to partner Santa Cruz at the head of the home attack.
But it was the Blackburn defence that was soon being tested as Larsson rattled the post with a fine free-kick from 20 yards out.
Blackburn players 'disappointed' - Kean
Rovers were unlucky not to get something from a frenzied spell of pressure in the Birmingham box as Roberts nodded a looping header towards Ben Foster's goal but the ball went over.
Roberts clashed heads with Blues defender Roger Johnson in the melee and Blackburn capitalised when the defender returned to the pitch after treatment seven minutes into injury time.
Liam Ridgewell, possibly distracted by Johnson's return, allowed Hoilett to nick the ball off his toes and the Canadian youngster coolly took the ball past Foster and slotted into an empty net.
Larsson brought out the best in Blackburn keeper Paul Robinson shortly after the restart, the former England man having to stretch to palm away the Swedish midfielder's smart free-kick from the edge of the area.
At the other end, Santa Cruz almost had the better of England goalkeeper Foster but he could only nod the ball on to the bar.
Birmingham had Foster to thank for keeping them in the game as the clock ticked down, the 28-year-old bravely taking the ball off Martin Olsson has he bore down on the goal.
Few clear cut chances were on show in a second half punctuated by a string of scrappy fouls and free-kicks and the game eventually fizzled out despite the high-tempo efforts of both sides.
Blackburn boss Steve Kean:
"I wanted to take a big leap today but we're taking little steps and we just have to keep chipping away.
"If all the teams around you pick up wins and you only get a point you're massively disappointed.
"But today we are probably a little bit better off than when we started.
"The atmosphere in the dressing room is really down. But we will soon come to realise that this is a good point today."
Birmingham manager Alex McLeish:
"We came back in the second half. We really could have crumbled after [the equaliser] but we had our backs to the wall.
"It was a bad moment for the player (Liam Ridgewell) but the next challenge for him was to see if he could recover from it and that's what he did.
"In the end I'm happy with the point. Larsson's free-kick crashed off the post but you can never rule Blackburn out with their long throws and some excellent footballers."
