Can anyone tell me why my 92 300D. Heater will only blow very hot air out the window vents while driving.
the fan control, climate control is not working in any functions, just blows hot air from window vents while driving. prior to that it worked intermitenly at some times blowing hot air out the window vents & cold air out the floor vents at the same time when trying to use the A/C. I don't know what needs replacing.
Thanks in advance for tech help
