Question about 2001 Pontiac Grand Prix

Open Question

My ac kicks on and off. Even if I just turned the fan on, it still comes on and goes off or takes a while to come on. I can hear a clicking noise near the steering wheel when it does this. What is wrong with it?

Compressor and fans do not turn on until rev engine


I passed this question the first time I read it, so I will take a stab at it now.
The fans don't come on until the compressor has pumped the freon pressure up to say 150 or 200 psi. And the compressor clutch has to have voltage to engage the clutch.
I wonder if the clutch is going and needs 14 volts instead of 12 to engage ? Or the relay that powers the clutch ?
Speeding up the engine would increase voltage from the alternator.
This is assuming the serpentine belt is tight and everything else is working correctly.
I think I would swap the relay with another and put a meter on that circuit to the ac clutch to see what it takes to engage it.

Filled Coolant reservior and radiator Drove trailblazer at highway speed no cooling problem. When slowed down in traffic temperature increased to about 220 and higher, could hear coolant bubbling in...


If there is bubbles occurring even inside the top part of the radiator (where you have the coolant put in), you may have a leak on your head gasket. You may be loosing coolant through the engine.

A/C blows good cold air and everything works as it should, however when I turn the A/C on (doesn't matter what fan speed) I hear a constant clicking/ticking noise coming from what sounds like a fan


What you are most likely hearing is the compressor kicking on/off. The constant kicking could be a sign that there's insufficient refrigerant to keep the compressor running continuously without shutting on/off. Eventually, the compressor won't kick on at all, a safety feature designed to prevent doing damage to a compressor that's undercharged. Have the AC system checked.

Groaning Noise While AC is on


this sounds like the AC compressor is failing, the engine idles slower in drive so noise is more apparent. you are likely going to need to replace it soon.

When the fan motor kicks in is making too much noise


the noise is the drain on the belt drive system upon AC start up, the belts may need to be tightened or the AC compressor clutch is in need of replacement, if you are saying when car stops you mean the engine is shutoff then this statement does not apply but if you mean when the vehicle comes to a stop at say a stop light then it applies.

I HEAR A LOUD WHINNING NOISE FROM UNDER THE HOOD


Yes there is a bearing in the AC clutch assembly, and the bearing can be changed with out swapping out for a whole new AC compressor unit or even taking the unit out. 
The other thing to you may want to check is the Serpentine belt tensioner. The tensioner then to break apart and or when the clutch activate put's more pressure on the system and the idler pully bearing could alsy be the problem. 
Spray some water on the fan belt whale the engine is running and see if the noise goes away and comes back as the water dry's. If the noise goes away then it's just a worn belt and need to be changed or you may want to do the quick fix and buy Fan belt dressing. 
Good luck and hope this helps

Ac blows hot


That sounds like the Blend Door Actulator has decided to go loopy. I heard of people turning it to hot and getting cold, Normally when this bit goes it makes a click click noise
