A quickie for you clever guys.

W211 climate control. The system needs recharging as one of the pipes was broken along with the pully spline that drives the belt/compressor.

Pully now repaired and the compressor is turning, but when pressing the A/c on/off button on the dash, it flashes a few times and then stays lit.

Any ideas? Does it sense that there's no gas in the system, or no? :confused:

Thanks in advance for any assistance. :cool:

With no gas the lamp will be on, it must be charged and the car put on STAR to activate it
