Title: Heating/AC and ECON only blows full hot or warm.
Post by: ksamyui on December 17, 2022, 11:14:55 pm

Bit of a weird one - haven’t had the car long - but unless I put the heating on LOW, it always blows hot regardless of the temp I set, Econ on econ off.

I know it’s low on refrigerant as there’s a VCDS print out in the files that says so. I would have thought though that even if the air con is knackered, I might be able to have a little bit more control than Full Hot or Cold?

Any thoughts? I’ve got VCDS set up but haven’t had a chance to learn it, so any help there much appreciated.

Cooling fans on radiator also don’t seem to come on. I’m going to run the output test on VCDS tomorrow to check they’re working; I read on another forum that the fan not working can stop the air con
