This may have been posted before, but all I need is a yes or no answer. Is it normal to hear my air conditioner "clunk" on when sitting still when I first turn it on? That's the only time I hear it. It doesn't do it if I start the vehicle with the air on. It's just when I start the car and then hit the air button.

That's the clutch engaging on the compressor and yes, it's normal.

Yes, it's normal, but it shouldn't be too loud and the noise shouldn't last longer than a second or two.

If the noise sounds like a grinding, or is continuous, then your a/c compressor needs to be looked at.

How do you get the compressor out of the engine?

2005 EX

I've got the bolts loose but i can't figure out how to pull it out. do i have to pull off the intake manifold?

From the manual:

4. Remove the radiator reservoir tank.
5. Remove the power steering pump (see page 17-15).
6. Remove the alternator (see page 4-31).
7. Remove the front grille cover and bulkhead
(see page 10-13).
8. Remove the A/C compressor clutch connector (A)
from the A/C condenser fan shroud (B), then open
the wire harness clip. Disconnect the A/C
condenser fan connector (C). Remove the upper
mounting bolts and the A/C condenser fan shroud.
Be careful not to damage the radiator fins when
removing the A/C condenser fan shroud

thanks all, not a very loud noise and it doesn't last but a second. I feel better now.

speaking of air con problems..... i have one... when i turn the fan on high, temp to cold, the air conditioner also kicks in...... the air con and MAX A/C was confirmed to be switched off....... even though the temperature outside is also cool, but i saw water dripping from underneath.....

any ideas?

You didn't say what mode it was in. If it's in defrost or feet+defrost, the a/c will always come on regardless of whether you select it or not (2008 owner's manual, page 105).

 

[hapyface]

just regular vent to face and feet.... so the A/C is also on when the A/C is switched off? or is it just outside air?

also what was the procedure to test the ventilation system? i recall reading it before but couldnt find it in search

 

[ramblerdan]

The compressor is designed to run any time the defrost or feet+defrost is selected. Shouldn't run on face or feet mode alone if not selected.
