air con

[ddtwelve]

Whilst I'm removing the bumper on my car to clean the turbo aircooler I thought I would check the air con clutch system as the air con absent worked on my car for ages even thou it's been recharged, the clutch did the click sound as if engaging so I know that works.
My point is can I bypass the in car on off switch directly to the air con clutch to get it working again??  it's a Renault scenic
