Where is the recharge port for the ac on Volvo 940?

The recharge port for the air conditioning system on a Volvo 940 is typically located near the driver's side of the engine bay. It can usually be found on the receiver-drier or along the A/C lines, with the low-pressure port being the one used for recharging. Look for a threaded fitting that is often capped; it is usually smaller than the high-pressure port. Always ensure the engine is off and the A/C system is not under pressure before attempting to locate or access the recharge port.
