Wolves suffered a setback to their fast-fading hopes of reaching the Championship play-offs as they were held by Crewe at Molineux.
Bottom-of-the-table Crewe took the lead on six minutes when Billy Jones fired in Steve Jones' cross.
Steve Jones struck the woodwork from 25 yards before Wolves keeper Stefan Postma made two saves in succession.
Yet Wolves grabbed an equaliser in first-half stoppage time when Mark Kennedy slotted home.
Wolves manager Glenn Hoddle:
"The first half was as poor as I have seen since I've been here. There's a bit of anxiety coming into the team.
"I didn't need to give them a rollicking at the interval because the crowd reaction was enough. I can't accept that performance.
"The second half was better but if I had known why we were so poor earlier I I could have done something about it."
Crewe manager Dario Gradi:
"We deserved it for the effort and we played some good football in the
"We tried to catch them on the break and got a super goal but perhaps it was too early. We needed to score two minutes from time.
"We have taken a point we didn't expect and stood up to Wolves very well. The ball was in our box a lot but we probably had the best chance."
