Nissan Repair: 1999 Nissan Altima, nissan altima, wd40

Question
How do I stop the squeaking noise when I turn my a/c on? All the belts are new and it still makes a squeaking noise when I turn it on.

Answer
Hi Dee -

2 things -

Even if the belt is new, it could be the wrong tension. With the engine running and belt squeaking, spray a little WD40 on the belt surface. If the squeaking goes away, then the belt must be tightened a little more.

The other noise it could be making is from the clutch on the A/C compressor. If the squeaking appears, and goes away quickly, have the clutch checked.

Hope this helps -
