I have several problems I think is vacuum problem, mechanic doesn't think so

What is your question?

The problem started about a year ago, the timing belt broke (2.4l), mechanic tore engine down completely could not find anything wrong, repaired and replaced everything that needed it, or that he decided needed to be replaced so we don't have to tear back into it. As soon as he put it back together, cranked it & let it run/drove it drove perfect, however the check engine light was on, he checked that turned out his code reader said crankshaft or camshaft sensor. we don't know which one. We picked the car up at closing time on Xmas eve, as soon as we started home we noticed the cruise wasn't working. Haven't been able to get it back to him, as we don't have another car can't afford a rental He says he did nothing to affect the cruise. then a few months later the car started stalling under heavy acceleration, now the hvac is cycling between vents, dash to defrost to heat & back. sounds like a vacuum problem for everything he says no

What makes this problem better or worse?

It's all equal as far as being cold or warmed up/hot
