Blower working on 1 side only
I have a 2004 Chevy Venture and the blower (Vent, AC, Heater, doesn't matter) is only blowing air out of the left or driver side of the van, nothing on the passenger side vents. There aren't 2 blower motors, are there? Is a door shut that shouldn't be? This van doesn't have dual climate control like my GM cars do. The rear controls work fine for the 2nd row passengers. Again, not tied to any blower speed or heat vs. AC. Same regardless. Nothing on the passenger side.

Re: Blower working on 1 side only
Is this a dual system?
You are correct....there is only one blower motor....so if you have good flow only on one side, there is definitely a blockage somewhere, meaning a possible nest?

Re: Blower working on 1 side only
No dual climate control. The air flow is absolutely zero on the passenger side and the vehicle is garaged so I doubt that it's a nest of any sort. Is there a flap/door that is stuck closed somewhere that would stop the air flow?
I just double checked it and this is only a problem on the Front Vent setting. When using the floor vents or the defroster vents, air flows from both sides. When setting it to the front vents (there is a driver left, 3 middle ones and a passenger right) air only comes out the driver left a left one of the middle 3. the right 2 of the middle 3 and the right passenger 1 have no air flow what so ever. Same whether heat, outside air, AC setting.

Re: Blower working on 1 side only
No. But they were replaced just a year or two ago. The vents worked fine one day, then did not the next. I will double check the cabin air filters though.

The front flaps are in the open position on all front dash vents.

Re: Blower working on 1 side only
Just because it's garaged, doesn't mean there can't be a nest....
Had a car that was garaged and ran poorly......found the air filter housing full of dry dog food, which was kept in the garage....
