A/C Clutch kick in and off

[Shaunhastie]

hi all my fiesta's a/c keeps turning off and on a lot and can feel and hear it when driving at 60 mph, I filled it up with a recharge as was low and it's in the green area and near middle range, so it isn't low on that. 

p.s the pressure goes up and down but still in the green when the compressor turns on and off.

Could have any help with this please, could it be the relay going or something else?

Any help will be appreciated 

Shaun

Do you mean the compressor kicks in and out or the a/c button light. If its the compressor it should build up pressure and fan should be in so it should kick in and out

Yes the compressor
