When I had my truck scanned a code came up for the ac clutch relay, ain't got the code number but it's not a constant noise, sounds like a bearing or something, anyone know any problem notorious relating to this? Or some tips as to check out where my noise is coming from

Josh. Is it like a belt noise or a bearing noise?

Turn the a/c on and see if the noise only happens when the compressor clutch cycles. Even though it may be cold right Now the defrost uses the a/c compressor to dry the air. It may be your compressor clutch.

It doesn't do it when the ac is on high

Anyone know of anything that's a common issue, was gonna check the tensioner and idler pulleys first, doesn't do it at all when the ac is on

Spray the front of the pulleys with wd40 and see if it quiets down. Only other thing you could do is take the belt off and spin the pulleys by hand to see if you can feel one grinding.
