On our '72, the AC, heater dash control is leaking vacuum in all switch positions, some positions worse than others. I disconnected all the hoses and found it is leaking at the switch body. Have an extra control, and the switch appears to leak on it too. Is this normal? Does anybody know if these are available new?

Thanks
Don
