It's really important to fix this problem because every time you hear the 
pop in the speaker, you're also giving the ECU the equivalent of a brain 
electroshock treatment.   After a while, you start getting a violent jerk 
in the engine. The info is on Scott Mockry's site at:

The harness installs easily into the wiring to the A/C magnetic clutch by 
separating a connection,  plugging in the extra wire and grounding the 
diode.  The relay replaces the A/C clutch relay in the panel below the 
steering wheel.  I got mine last fall from Carlsen for a little over $100, 
I think.  The harness and replacement relay  are dealer-only according to 
the nondealer vendors I contacted last fall.
