A/C Causes Shudder on 2000 Accord EX
 

I have the 2000 Honda Accord EX, around 100k. When I turn on the A/C
the vehicle shudders. It's not a crazy/exaggerated shudder, but as the
rest of the ride/driving experience is so smooth it is seemingly
unnecessary.

The timing belt should be replaced but the even when the A/C is not on
the timing belt doesn't seem to be a contributor. If it is, it's only
in a small way.

What could I do to start the process of troubleshooting besides
spending lots of cash?


Thanks in advance,
