I live in CA and im going to explode if i cant figure out whats wrong with my ac.

So the fan and ac both work at the lowest 2 settings. If i turn the fan speed up to medium high or high it stops blowing cold air. The fan still speeds up like it should but the ac light turns off and it blows room temperature air. Maybe 1 in 20 times it will blow cold air on high but the light will eventually flicker and turn off and then im back with room temperature air again (

2007 Saturn Vue V6 if that matters

any help would be greatly appreciated by me and anyone else that rides in my car

 

God didn't break it. Why would you want Him to damn it for you? He may be the only one who can help you.

 

Sounds like a CARB compliance issue where Saturn had to make some changes. But I'll keep researching

Also, your username is very distracting and in fact, there is a regular who, among other things, is a minister, but I can tell you before he gets to this post that as soon as he sees it, he will be pretty pissed off at you using the Lord's name for a username in vain.
Personally I have no issues with people that believe in God, don't believe in God, are passionate about their beliefs in God. Just don't be offensive, dude. Assuming you are a dude, dude.

 

I don't know one damn thing about how the AC works on a 2007 VUE, but here's my take.

Everything works fine on the lower blower settings because the voltage and current required to keep the AC clutch engaged is present.

Asking the blower motor to spin faster should have zero effect on anything besides the blower motor inside the car. If the light goes out on the AC button, I'm willing to bet that the AC clutch disengages from the compressor at the exact same time.

The blower motor doesn't know and doesn't care, it just blows air, which at this point is warm because the compressor is not compressing because the clutch is disengaged.

Same deal on the highest lower setting.

The other difference to note here is that the highest blower setting is usually achieved by patching battery voltage straight to the blower motor, bypassing the blower motor resistor pack circuitry. So if it misbehaves on the top setting and the one below it, it is unlikely to be related to the blower motor resistor pack.

To me it sounds as though either your blower motor is drawing too much current in order to spin at its directed RPM for those settings, or your alternator is not putting out enough current to supply enough current to the whole vehicle including the blower motor and AC compressor clutch.

Both have the same effect on the inability to keep the compressor clutch engaged.

I suppose the compressor clutch itself could be defective, but someone else will have to chime in on that because, well, because.

To test all of this, just have a pal watch and listen to the compressor under the hood while you change the speeds on the AC blower and he should hear a clicking by the serpentine belt by the AC compressor which is the clutch engaging.

 

Noice!

 

Thanks, Dude.

And we'll never know how wrong I was.

Can you believe I gave advice to someone and they never came back? Not even to flip me off?

I'm not sure if that's ever happened before.

All I know is it hurts deep down inside.

 

Well done G

 

You'll have that Derf.........knuckleheads abide....have a great day!

 

It never ceases to amaze me that people jump on the forum and want an immediate answer on how to fix their car. If they don't get it, they get mad and move on. We don't need chumps like that.
