It's hot once engine warms up, & can't be turned down......
Wee bit of history. It worked fine when I got the car early this year, & worked ok until I started working on the centre console illuminating lights. (Heater controls, clock & fuel guage)
I've now got them sorted out, car hasn't been used much, & other jobs were done in fits & starts.
Two heater control units have been tried. Two sensors that plug into heater loom have been tried. No difference.
I'm not sure if I can increase
the temperature (wouldn't want to though) but turned fully down cabin gets toasty.
So it seems I've done something, but don't know what to do next.
If you've got a suggestion, spell it out nice & simple please...
