I just replaced my ac compressor for my integra because it made that clicking noise all the time, so I'm pretty sure it was busted. So i got another barely used compressor. This one is charged correctly and now everytime its like 100 degrees outside my compressor or the ac clutch would start to click for a few seconds only at a stop light. But it still blows cold air. Just wanted to know if this is a sign that my compressor is about to die on me again?

Could be low pressure, bad pressure sensor/switch, bad compressor (clutch) relay.. though.. you likely could use a good recovery and charge (and/or recycling). Could be that you could stand more oil in the system.

Oh thanks man, i forgot about the sensor/switch.

Prior to installing the replacement compressor, did you do a full vacuum?

im new to the a/c world but i thought you dont have to do a full vacuum on the 134a system? if its 134a. only on the r12 system.

BentValve

AFAIK, when a compressor goes bad, it can contaminate the lines with debris. If the lines are not properly vacuumed, when you install the new compressor, the debris can enter and destroy it as well.

Thats prolly what it is cause it was vacuumed. Also, when i recharged it, i used the 134a with the oil in it. That should be enough oil for the system right?

When does the "click" happen? When the compressor comes on?

Show Pow

Yup, just when the compressor is on and when i put the a/c on the 2nd notch and higher (still blows cold air). If its just on the first notch it won't do it. Also it doesn't click if it's not really hot outside. Its fine at night time. The only last for a few seconds or when i start moving from an idle.
