When you bypass what?

is there any hidden relay or fuse in the interior bay.

I don't think so.

If I helped you fix it, why not...

Your support is greatly appreciated​

Bypass means when I removed the relay and used a paper clip to jump the compressor it works

So the engine ECU is not switching on the compressor relay for some reason. Low gas pressure is the most common reason for that to happen. I assume you had the AC system recharged after you fixed the leak?
