Fan blower switch on high speed works sometimes but not others. No rhym or reaso
What is your question?
Highest speed on fan blower works off and on. Replaced resistor. No change. Mode setting dial on dash board for heat, a/c, Max, vent, blend seems slightly mushy when finding specific printed stop points per labeled stops on heater/ac controls on dash board. You can turn the dial past all of the labels without feeling a click when passing by each labeled stop point. Feels as if dial needs to be tightened to circuit board from behind heater face plate ???????????????
What makes this problem better or worse?
No obvious actions causing issue to take place
