absolutely love our minnie winnie (2003) and while i haven't found a big problem with heat at the floorboard while driving (driver or passenger side) as i've read on this forum, we do seem to have a 5" round vent that evacuates HOT air from under the passenger bench at the table that seems to have no way to be closed off in the summer while we're trying to run the air conditioner. can't seem to reroute the air or shut it off. impossible to cool the coach while driving and quickly reached over 82 degrees last weekend. while it would seem more expedient to run the coach air conditioner than the chassis a/c, it makes no sense to do either if we can't shut off that hot air.
what's up with that?

That sounds as if your furnace is running when you turn the A/C on. There may be a problem with the thermostat, if it controls both.

If you are having this issue when driving and the AC is the dash air it could be as Tom said and your furnace thermostat is set for heat and is on.

thanks, fellas.......but that's one of the first things we were told about--not trying to have the coach furnace on while driving. (tech said it'd just blow out anyway.) however, we usually use the heat pump unless it's terribly cold (20's)(then have to switch to LP)....so we couldn't have forgotten to turn the furnace off as the thermostat was switched to a/c (thermostat is one that does a/c [left][off]--gas [heat-right]--electric [heat-most right]).....actually it feels like heat off the engine, but can't imagine that is ducted to the coach.

That size vent has to be supplied by the furnace, not the vehicle A/C.
Just about any RV dealer should be able to supply you with a directional/closeable version of this vent for under $20. Make sure the furnace is off as well as the vent outlet and you should be good to go for just a few bucks in parts and labor.

Do you have a rotary knob on the dash to the left of the steering wheel that has 4 positions??
Usually this knob is close to the battery Aux momentary rocker switch.
If you do your Winnebago has the MotorAid option.
Also if you have this option have you noticed that the water in the hot water tank is hot after a long drive even though you did not turn on the water heater.
The MotorAid option is hot water lines from the radiator run to the hot water tank and to a heater for the coach. The knob on the dash is a 3 speed fan switch with a off position. You should depending on the floor plan of your coach have a vent under or near to the dinette and another in the kitchen or somewhere in the hallway between the kitchen and bath. These vents look like the normal rectangular house vents and not like the normal round RV furnace and AC vents.

Just re-read your post and I see you said round vent.
Now if your RV is not a basement model then it may have round vents with the MotorAid option.
The rectangular vents are in basement models since the ductwork runs under the floor just like in a house, and the vents are in the floor or cabinet toe kick but still coming from under the floor

oh my gosh, kgmz! you nailed it! sheesh! not an option pointed out by the selling dealer or anything i've noticed in the papers/booklets/pamphlets we got with the rig. i took the camera out to get a photo of the round vent (yes, we do have a pretty good basement with a winter package), but first hopped into the cab to check for the knob, which i was pretty sure wasn't there. there it was! and when i went to turn it--it turned left 3 positions to off. HA...it'd been running on high every time we've had the rig out. and yes, we'd noticed the convenience with the hot water heater. it don't take much. the vent is indeed right under the dinette bench and can really put out copious amounts of heat.....keeps the coach downright comfy even in march when we were out in some freezing temps....but then those temps turned warm.
thank you, all, so much and especially, kgmz, appreciate your dead on diagnosis. gees, i love this forum and that minnie winnie. it has had so many thoughtful touches added, we obviously haven't found them all yet.
