Golf mk7 / Re: Hot air blowing only from passenger vent issue
« Last post by 2007GTI on 27 November 2025, 22:03 »Thanks, that is the only likely culprit left, so will probably end if changing it.
Having a similar issue with my GTI whereby the passenger side vents can blow out nice hot air but all those on driver’s side won’t get any more than tepid.
Tried doing the A/C reset trick but that didn’t make any difference.
Took it to dealership who said that heater matrix needs replacing but that wouldn’t be covered by the All-In extended warranty; unlike the thermostat housing which got replaced a few years ago when there was a coolant leak and they removed the dreaded silica bag.
