99 Accord heater / A/C control?

Question

Any Honda mechanics hang out here?Anyway.... I have a 1999 Honda Accord EX...  withthe manual heater / AC controls.  My switch to controlthe fan speed only works on one speed and I can feelthat the switch has "slack" in it so its my assumptionthat the heater control unit needs to be replaced?I believe Honda calls this item the heater control unit...while other manufactures may call it the A/C control head.Is it basically a direct swap out to change one of these, itanyone knows.I'm talking about the control unit in the dash that operatesthe heater / ac fan speed and the temp.Thanks, Elbert-----------Elbert

It sounds like the keyed socket on the inside of the plastic roundcontrol has broken.  Have you pulled the black round plastic controlnob off to see?Mine broke a couple of years ago and I did a crude repair job on itwith a little plastic cement.  The controls for the fan and temperaturesettings are the same and I switched them as the temperature settingcontrol places less torque on the keyed socket.  I haven't have aproblem with either since making the repair and switch.Elbert wrote:

Which speed does work?I think your problem may be with the blower resistor module.
