The economy button LED on my climate control stays on unless the button is held in, take your finger off and it comes back on. Does this mean the Aircon is Broke? This only just started after a bump to the passenger front resulting in needing a new bumper and wing and I see that the air con unit lives in that corner.

 

Yes it means you have no ac. Check for damage to the condensor. I suspect you have a leak somewhere that is causing your ac not to kick on.
