I am at a loss here. I recently had issues with my radio and HVAC controls as well with the display due to plastic cracking and letting the harness and radio half seperate from the control interface half. I decided to bond these two together around connector areas and screw interfaces. This has solved my radio, HVAC, and display issues, but now my AC seemed warmer these past few days. I thought maybe it was just the heat wave that seemed to be moving through but today I noticed my passenger side AC vents were a hell of alot cooler then the drivers side including the far right vent and even the floor vents for the car. I tought how in the hell could this be possible since they share the same ducts at least I would believe they do. I then searched online found photos and it appears they do share the same vents and have also found similiar complaints with the RX8. This just seems to weird for me to figure out. I mean the temperature coming out of all drivers side vents feels like there is no AC and its just a fan and all the passengers side vents seems like there is AC.

Has anyone had this issue and if so what is the cause? because from my standpoint this makes no sense once so whever.

Thank you in advance ZOOM ZOOM!

 

I skimmed through the HVAC part of the repair manual and came only come up with two things.
First, since you apparently have all these cracks................has the car ever been in an accident? Is it parked outside?

Here are the two things:

1.) There is a blockage in that side. It's been known to happen. Hell people have even had rats and squirrels make homes in the airbox and other places. Not sure how'd they'd get into the duct system, but might be worth a peek.
When you were fixing what you were doing, you didn't leave a rag in there somewhere did you?

2.) When you were fixing the other stuff, did you happen to mis-align and vent ducts or anything? The manual actually says.....check to see if the duct system is installed in the car! WTF?

3.) Long shot...........have you checked the cabin filter? Who knows, maybe that's it? Maybe one side is blocked and not letting air through to that side????????

 

yeah I would check for a blockage as well. another thing that happens but isn't as common is something ends up in the vent, and knocks out the blower.

 

I'm having the same issue.I've scoped the far left vent as far in as I could and couldn't see any obstruction. I removed the passenger side dash to see if anything was not put back in place when the air bag was replaced. Everything was in order. The cabin filters are clean, no fan obstructions. The vent ducts are present and in place. Were you able to solve this issue? My last option is to remove the center dash and ducts . That looks like a real PITA! Haha

 

Hi.....did anyone find a solutin to this problem? I have the same, left side (US drivers) AC, right side (UK) flow but no AC. Stuck camera down and alls fine.
