My ac compressor is surging.
Clutch goes on off on off repetitively. Like a surge.
It blows cold but is drawing power from the motor.

When i first start it its fine. Then i rev and hold it at 2000 rpm.
Then on off on off on off on off.

I checked all the relays and fuses. They are all good.
The low pressure is fine. Cant check the high pressure.

Its a 1996 civic coupe.

 

a/c blowing will "drain" some power from your motor, and as long as its not feeling like its going to stall out while driving i think you are ok. you could always see if a new/different compressor helps. yours may or may not be on its way out.

autozone ftw for stuff like this

edit: nvm still expensive as **** from autozone

 

I don't think you can avoid the power draw but the compressor surging could mean your system needs a charge.

 

You Hawaii guys have the best weather. It is finally above freezing where I am.

 

yeah it feels like its going to stall then back up again.
As for autozone we dont have one.
Checkers
napa
redline
cw carter
hawaii imports
pacific jobbers
or the dealer which i never go to.

I checked it with the gauge that comes with the refill can at wal mart and it says its good. (only able to check low pressure) I may have to borrow a friends set of ac gauges.

Yeah it is nice but then it starts to rain. Then the windows fog up. And if i use the heater it gets worse only the ac helps prevent the windows from fogging.

 

Oh yeah i know that it draws power when its on but not supposed to draw like this.

 

Mine use to do the same thing. I added some oil to seal the unit and then put in some freon. It was frigid cold. If it doesn't last, you could need o-rings or have a slow leak.

 

Check the condenser fan, I had a similar problem with AC clutch bouncing around. The fan should be on when the AC is on.

 

i dont think i have a leak. The system still has normal pressure.

the fan comes on like normal.

Could it be that it has too much pressure?
Or the reciever dryer is clogged? I noticed a sensor on it and when i disconnect it the clutch goes off.

 

True!
