Default Problem with dual zone aircon

Hello good people of peugeotforums,

I've been having problem with aircon eversince i got the car, but recent searing hot days have prompted me to seek help.

First off, i believe problem not to be in cooling or heating or leaking installations, as the air coming out of vents is usualy pretty cold, certanly cold enough to cool the car down.

The actual problem i am having is actually in the volume of air coming out of vents. When i set the aircon direction arrows to side and down, to blow towards me and my legs, the volume of air coming out seems a bit low.

The aircon button for fan speed seems a bit silly too, when i set to 3 full fan blades, it blows quite slowly, not too much difference between 1, 2 or 3 levels or levels in between, but when i switch to 3.5 or 4 blades, the fan all of a sudden starts blowing quite loudly and increasing the volume quite a bit, but still its below what i would expect to be at its max.

I have also noticed that volume of air coming out of my passangers side is always somewhat lower than on my side. And when i turn on recirculation, it starts blowign quite loudly, like another fan comes on, but still volume of air seems low.

Anyone have any ideas? Could the cabin filter be plugged up or something, failed motor? Would diagnostics show up any such problem if it infact exists. How do your aircons serve you?

TL;DR My aircon seems to be blowing too low for my liking.

Thanks chaps,
Iva

Theres a problem somewhere.... as you turn the fan speed knob up each half blade, you should hear/feel an increase in air volume - I do with mine from 1 to the full 8

Agree with Nige, check the filter first, then look to the fan motor/controller

Ok, thanks guys, i will try that. So do i just need to take off A panel as show on the diagram?

I did take a quick peek to look for pollen filter when i was fiddling around with glove box compartment, but i saw nothing there. Mind you, my car is the left hand drive, or what you call it, my steering wheel is on left side. Im confused by the terminology. :P

No need to remove Panel A.

When you find it, you will see a black plastic panel held in with a clip at one end - its about 50mmx200mm or so. Find panel A, then look upwards, right behind the console - not the easiest thing to get to.

Yours being LHD, you will gain access to it from your drivers side - I believe this wasn't swapped between LHD & RHD.

Hi guys, just an update.

I pulled down the sound proofing by undoing the two plastic screws, and found the pollen filter right where you said it would be. As a bonus i took few pics for future reference for dummies like me. The filter box is actually labled pretty straightforward, its just the matter of looking at the right spot.

I proceded to take out the filter, and clean out 2 bears fur equivalent out of it. Needles to say, aircon works like the car rolled right out of factory, now at 4/8 it blows as hard as it did at full strength before cleaning, also the ugly gurgling sounds from aircon are gone. YAY! And to think that all aircon repair shops told me i need to get it refilled and whatnot for atleast 40-100EUR price. Buggers.

Cheers for the help guys. You da best.


On the images the filter cap is labled FILTRATION, with some yellow stain on it, atleast on my car. One pic upclose and one a bit further away to show its exact position.

Guys,

I have the exact issue as discribed here, but there's nothing blocking the filter and even with the pollen filter I still have very poor volume of air and it's quite noisy as I can hear something blocking the air. What else can I try here?
