sound(chirp) coming from AC pressure sensor

[00spy]

I know I posted another thread for my A/C ? ,but this is kind of another question dealing with my cooling fans. I noticed this morning with the A/C on ,the fans still cut on and off ,but I was standing on the passenger side next to the windshield washer resevoir and heard like a slight (chirp) sound ,and I think it is coming from the AC pressure sensor which is beside the resevoir (I think that is what it is called)I can hold the plug and you can also feel it when the noise is made and the fans cut off.I hope maybe this can narrow down my problem ,if anyone has a suggestion I will be grateful ,Im scared to drive this thing too far ,although it does not show overheating ,I would like to solve this problem ,but I am limited to my knowledge on this situation.

I also found out that I can touch the black relay and it will have a pulse when the fans come on and off.
I checked the voltage to the green relay and got , well my meter read -6.93v and the yellow relay next to it had no voltage to it ( i think it is the clutch relay). all of the other had 12.95v . just trying to update my progress. when A/C is on the clutch to the A/C is always moving ,it never stops.

I also noticed that I left the car running for a while and the temp gauge just barely started to touch the N , does that seem normal , I think even being driven it is the same.
