No a/c. Possible ECU Issue?

No a/c. Possible ECU Issue?
Hello all! I have a 2007 RDX (130K) with an a/c issue. A couple of months ago, the a/c would work sporadically (and even stay on when the control was off!). Full disclosure that I was fiddling with the left fuse cluster under the dash when I sparked something. However, to bring you up to date, here is what's been done by me and three (yes, three) shops:
What I did:
Thoughts on any of this? Thanks!!!
What I did:
- Checked all the fuses under dash and all were good, and even replaced any dealing with HVAC.
- Replaced the relays and associated fuses in the engine fuse box.
- Replaced the center console HVAC controls
- Replaced the passenger side HVAC control, module
- Was able to get compressor started by jumping wire
- Tested a/c and it was fully charged
- Also checked those relays
- Was able to get compressor to kick in by jumping it directly
- Said it was an electrical issue
- Kept for two days while testing
- Said it needed a compressor (I did not get it as I and the first shop were able to get it started...which I also informed the dealer)
- Successfully jumped compressor and also confirmed a/c was fully charged
- Said it was electrical and most likely the ECU (and that my little fusebox spark may have been the culprit)
Thoughts on any of this? Thanks!!!

I replaced compressor instead of fooling with Honda’s clutch kit . I think jumping compressor adds a bit more juice so it does kick in ..just a wag though . Me personally I don’t believe you have some electrical gremlin .
Can you tell if the compressor has been replaced ?

Same here on a 2010 Honda CRV. I took the one washer out, not expecting much, and it has been working for two years now. With a little washer mind you. Go Figure. Of course, I had to do this in Florida summer heat, so that was fun.....
