2017 Ford F150 XL, 95,000m, heat only when driving
I only get the heat to work when I'm driving above 20 mph. It was working fine a week ago and now it makes this gargling sound when I start it and drive it. I added coolant to the reservoir and it turned it back on for 2 days and back to normal.

You either have a leak or a faulty radiator cap. Check that it's fully seated on the radiator neck. Check for leaks, your antifreeze shouldn't be dropping.
I'll try the Air purging techniques I found on YouTube and then check for leaks. It's like -5 here so I need this heat! Lol
