Climatronic (AC) not working

[danieljmarsh]

Hi all, I have a skoda octavia mkIII and the climatronic control is playing up.

 

I get hot air from the passenger dash vents, but only cold air from the drivers side. I've tried recalibrating the valves but that hasn't improved the hot/cold situation. 

 

The local skoda dealership have investigated, £100 for diagnostic scan and no fault found. They want to book 3 hours further investigation (£434 + vat) but they don't really seem to have any ideas so I'm a bit hesitant to fund this ongoing work at the moment.

 

Has anyone else experienced this fault, and if so how was it resolved? 

 

The dealer also quoted for a new heater matrix at £278 + vat, but about £1200 labour to fit it and another £900 for a coolant flush, is this the standard cost?

 

Thanks for any advice in advance!!!

Hello Daniel, welcome to the forum. What colour is your coolant - is it discoloured? 

 

PS. I think they're taking the p**s for the coolant flush.

Can't see it being the heater matrix as I think there is generally only one of those so if you're getting hot on one side that shows that it's working.  My guess would be an issue with a heater flap motor or one of the temperature probes in the dash vents has had it or become misplaced as I think there is one in each side.

Hi @Warrior193 I had a coolant leak that was repaired recently with the thermostatic housing being replaced. The coolant is all fine and it hasn't discoloured

@skomaz thanks, I found similar on a Google search and this seems common with the VWs and Skodas. Do you know how easy it is to access the two air-conditioning sensors in the dashboard? It's probably cheaper to replace both of them,  than pay for an hour of dealer investigation but I could swap them over to see if the the fault moves side first

Not sure to be honest but diagrams on 7zap seem to indicate they are located on the air ducts to the vents at either end of the dashboard...  Items 12
