Someone out there has had to of had the same heating issues that I’m having. Both my MK1’s are having issues. My burgundy one will blow straight heat all the time. You can’t adjust it at all. Just the blower speed. The heat in my other one is working at the moment but on my way into work this morning I was hearing a random clicking sound coming from behind the dash as I set the temperature. It would continue for a few second then stop then click randomly again. Any ideas where to start with these? I really need to fix the full time heat issue in the other car. It makes it hard to drive.
