2006 Burb Intermittent A/C

My hotwire situation uses the hi and lo pressure switches to make it a safer hotwire for the ac system. I'm a retired master tech and sometimes the juice is not worth the squeeze on an older unit.

Are you saying the BCM is at fault and you are bypassing the BCM control over the AC?

UPDATE: Oct. 27, 2022.
Dropped off the burb at a shop.
Had the PCM replaced with one from company Flagship One. The shop replaced the HVAC control on the dash. Spent a few $$$$
Drove home agitated. Same issue. No AC. Not cycling.
Took it back today, a week later.
Evac system and refill. It was low maybe less than 1/4 lb of freon. Same issue. No AC. Not cycling
Changed the pressure sensors that I already replaced. Same issue. No AC Not cycling
Had to leave it overnight and they are going to check it out tomorrow. The mechanic doesn't know why it isn't working.
This is exactly why I took it to a shop because I already did everything they did and thought I needed a more experienced mechanic....I guess I was wrong.

Could have been the original problem or a combo of the other components replaced.
AC is working now....
