:confused: Hey guys,

What is this UNIT under the hood??? I am getting a clicking sound from it??? I am assuming since i am having problems with my AC and i have a leak???? and my level is 00 on the climate control. It clicks when the AC is on. So is it related to no r134a in the system....????

thanks
chris
