A/C cutting out unexpectedly '05 Odyssey

9 months ago, A/C was significantly warmer on driver’s side , but fine on passenger and rear. 3 days ago, it started just cutting out in the whole vehicle especially with braking or acceleration (but not always). Pressing the A/C button will start it back up.It seems to me like maybe electrical , but the honda mechanic ran the diagnostics 2 weeks ago and found nothing. Thoughts?

I wonder if a vacuum leak might affect which blend doors open or close inside the ventilation system.

Amount of vacuum changes when you brake or accelerate.

Just a follow up. The problem turned out to be two fold. Firstly a bad transistor for the front blower and a secondly a hole in the condensor from a rock impact. Seems to be working fine now after those things were fixed.
