2001 4.0L - Sounds like A/C compressor cycles off and on when heater is turned on?!

Hey guys,

When I run my heater, I get an intermittent buzz and raised idle; and it sounds as if the A/C compressor turns off and on every 3-4 seconds or so.

Does anyone have any ideas what this might be?! I'll hear a buzz/hum from the engine, the idle will raise a few hundred RPM, and 3-4 seconds later it stops. It keeps doing this about every 5-8 seconds.

I'm baffled!

Weird...never seen this on any other car, and I've had close to 20. Haha. Thanks!
