Help Please HVAC not working

[BazzerA4]

Hi all,

My passenger side vents have randomly stopped working and the aircon doesn't work either. The aircon issue is more than likely due to the pressure sensor but the vent issue has stumped me.

Here is a scan from VCDS:

Any help is appreciated!

Thanks

Ideally it needs calibration, goto into hvac & under basic settings there's probably a run routine which resets the motors etc.

Already tried that, sadly both failed.

Then it would appear you have faults with either multiple motors or a common supply, maybe a fuse or wiring issue or even climate unit.

Guess I'll have to book it in somewhere, thanks for your help!

Sounds silly but I recently thought mine was broken, my daughter mentioned that there was no aircon coming through on her side of the car. I was frantically open and closing the vents e.t.c thinking great what's up here when she suggested that I checked the climate setting's ..... somehow I'd shut the an speed right off on the LHS but mine as on full...I'd forgotten that you could adjust one side of the car independently to the other

With those faults, I'd go out on a limb, it's not fan speed as he's got motors, flaps with no comms, but it's a fair comment to remind people as often I naturally accept people haven't played with settings to the degree they've disabled the system lol.

Have you tried pulling out the HVAC controls unit (pops out with a flat trim tool very easily) disconnect all plugs and reconnect?
Probably won't work but anything is worth a shot.
