hey guys quick question...I have a 2008 1500 4x4 QC roughly 48k miles. Last night I turned my AC on and a very loud vibration started. sounded like from the front of my truck. It only happens when the compressor is on. Please let me know what yall think.

Thanks

 

check the condenser fan--the smaller one on the drivers side to see if its loose or a broken blade, other than that, you may be loosing the a/c compressor. It may be possible that the serpentine belt is causing it, but it would have to be in really bad condition to do that. It might be better to have someone turn the a/c on while you're watching it.

 

Thx I'll try that

 

My best bet is compressor namely the clutch or bearing going out

 

Well fixed it. Cleaned the condensor and vibration went away. Thanks

 

Just cleaned the condenser or the condenser fan its self?
