2004 Ford Explorer XLT Flexifuel 40000 miles

Hello!
When pressing down the accelerator there's a 'hissing sound' coming from somewhere under the dashboard at the front passenger side (only appears at the very moment of pressing down). It's no difference if running on either gasoline or ethanol. The car is equiped with a 'Fuel Pump Shut-Off Switch (fuel reset). Could this have something to do with it?

Regards,
Ehlderado, Sweden

Do all the heater- a/c vents work properly? There is a vacuum feed that comes into the truck on that side that controls the HVAC system

I don't know about the cooler though it's been winter and cold here in Sweden since I bought the truck. But the heater and fan works ok. Also when turning on the 'full A/C' mode the heater and fan seem to work ok. It's only in the beginning when applying the accelerator the 'hissing' sound appears then it stops.
