Sucking sound

I noticed today when i had my heater on in the front and back of my 2001 that i heard a sucking sound coming from the back. Happened abot every 2 minutes or so. Any idea's what it could be and should i worry about it. Vents seemed to be working fine.

Bill, was her name Kathy? Sounds like one of my old girlfriends.....

Seriously, there is nothing in the back that is related to the heater. You have the core and blower in the front of the truck and another blower (booster) in the center console so I don't have a good answer.

Well, wait. My Expy has front/rear heat and A/C. That system doesn't use a blower within the console, but uses a blower all the way in the back.
