The passenger vent blows very cold, The other vents are progressively warmer moving from righ to left. Every vent has good flow. Help! Please help!

 

could be a blender door actuator not fully opening. i would locate yours and try to manipulate it to open fully to see if it helps

 

Thanks for taking the time to reply to my cry for HELP!. That's my thinking at this point too. It would stand to reason that it is only allowing a small amount of cool air into the vents, with the vent on the right the closest to the source of the cool air, and not enough cool air to spread out over all the vents. When I close off the right vent the air in the other vents seems to be a bit cooler. However, given the 96 to 100+ weather we have had it is hard to tell.

My brother is going to pull the blower motor off this weekend. Can you get to the actuator from there? I have been told it is an all day job and then some to try to dismattel the vent system from within the cabin.
