Defroster not working on 4 is a classic symptom of a faulty heater blower resistor. Check and replace that and you will likely have your blower speeds back. Furthermore, please check your wiring connector at the resistor to make sure there is not any melted terminals or wiring issues.

The heater will not blow air through the floor vents. The blower works fine in all settings, but the vent damper motor will only move to defrost or face. When floor is selected face is opened.
all the time. Blower doesn't work for heat or defrost
I pulled the dash front and removed the control device, took it apart, cleaned the brass contacts but no luck. Any advice before I buy a new control? Anyone else have this problem?
