New heater valve 9 months ago
Is the heater core supposed to have heat regardles of the heater valves. My heater box always has heat and the passanger defrost vents and floor vents have heat with the dials set to cold. I have the center console out and I noticed the heat all the time at the box. I replace the heater valves brand new from Vines BMW about a year ago. What is the correct way to test them and are they capable of sticking that quick.
Its a 1990 525 with manual slider and the 3 control knobs driver---- fan----passanger knobs
Thanks for any help
