I have 2002 Honda cr-v. For A/C 1. Why a/c clutch engaging and disengaging on my cr-v? 2. Do I need to change high pressure valve?

I have 2002 Honda cr-v. My car A/C is not working good. A/C clutch engaging and disengaging problem. When a/c clutch engage that time Freon pressure is 30 PSI at Low side and when a/c clutch disengage at that time Freon pressure is 100 psi at Low side. On compressor has high pressure relief valve. Sometime high pressure relief valve open and Freon is coming from high pressure valve. I have HS-110R Keihin compressor on my cr-v. High pressure valve p/n: 38801-PCA-006 ( Valve sub. Assembly… From Honda dealer )
My questions:
1. Why a/c clutch engaging and disengaging on my cr-v?
2. Do I need to change high pressure valve?

I have a 2000 Honda Crv with an electrical short?

I have a 2000 Honda Crv that has a short, if it sits overnight, it will run the battery down to being dead
I put the multtestor on it and it shows an excessive draw in the condenser fan fuse line. I put a new condenser cooling fan on it and it still shows the same.Had battery tested, it is fine. What could be wrong?
