air blowing slow when hit breaks.

On my 1999 Jeep Grand Cherokee when I hit the breaks when driving the vent is set to the low position the vent will basically stop shooting out air when let go of the break the vent then begins to shoot out the air again. This happens at any position the vent is at, a/c, heat, face , feet etc.. When the blower motor is set to a higher speed this then doesn't happen only at low. Does anyone know what could be wrong. TO me it seems like a potential vacuum leak somewhere but would like to see if someone can point me in the correct direction to start and see on this issue. It isnt a big deal right now but want to make sure it doesn't get worse as it gets closer to fall and winter coming before you know it. Id rather try and fix now then wait till it gets worse.
