No warm air only cold

Hello, recently my car started blowing only cold air through the air vents but not hot air, even when I set 28 plus it’s not blowing hot air, what could be an issue?

Thanks

Check if you have hot water coming into the cabin area by feeling the pipes in the plenum chamber. There is a valve there which could be the issue

Thanks Morski, where those pipes are? More over I scanned today with carista and got those codes: I think I need a visit to my dealer. Also my front window is foggy when driving in a rainy conditions, only helps when using ac with to defrost window but it’s very cold inside a car

Take off the panel under the windscreen. You will see the 2 pipes entering the cabin area from the engine bay. there is a pump there as well so check the temp on the pipe pre and post pump.
Until you get the air temp sorted coming into the cabin you will have condensation issues in the cabin

It’s strange but it started warming up, not sure what happened….but it fixed itself
