Had this problem for a week or so. Everytime I start to drive
the 01 civic (auto), there is this loud rattling and clicking sound
coming from the passenger side of the car. It alternates between
clicking, whizzing and rattling. Sounds like something is loose in
there. When I turn the A/C off, it was ok... 
WEnt to KAh Motor, they said that it was the air con compressor
problem, and they quoted $1.4K to replace the compressor. 
Anyone else experienced the same problem and how did you solve it?
If it is really the compressor, do u have any contacts?
