Slight surge at idle
Hi guys,
Quick question, noticed that when the HVAC is on, any setting, I get a slight cyclical surge in idle. I hear a clutch kicking in and off at the A/C, around 15 second intervals. Low pressure in the A/C maybe?

Your e-fan tends to cycle on and off when you have A/C on (and defroster I think, but I've never have used that setting here, in the 5 years I own mine haha).
This is normal operation.

Roler is correct, however if you have a low refrigerant charge the compressor/fan will cycle more often. If it's happening every 15 seconds I would think that your original thought of low pressure is correct.
