Sorted out the A/C on my ZT.
Replaced the condenser and switch and new o ring seals.
Brought all the necessary items to vacuum out all the air and refill with the correct gas and oil,now i have a chilled ZT.
I attached the vacuum pump and gauges to the A/C system and let it run for 1 1/2 hours.switched it off and left it for another 1 1/2 hours to see if it held vacuum,which it did.Then i disconnected the pump and attached the A/C oil then gas and refilled the system.
