It took the whole can, but the gauge still reads 0 and I'm not hearing a difference in compressor noise when turning the a/c on and off. Is the clutch bad or should I try adding oil and another can.
The A/C system is normally a sealed system. This means the R134a only emptied if there was a leak. This system holds approx 24 oz of R134a (check label under the hood or near evaporator) so one can may not activate the compressor due to low pressure in the system.
Before adding anymore, check all tubing, the condensor and near the compressor for signs (oil leaking, hissing) of the leak. Good Luck
