tonyny Posted September 18, 2009 Report Share Posted September 18, 2009 Recently when I started my car I heard a tapping sound coming from the dash area. After a bit it stopped and the a/c came on. Shut the car off when I arrived at my destination and when i started it up again same tapping sound but this time the a/c didn't kick in. Seemed like it was blowing from the floor area. So I drove without a/c than on the way home I tried the a./c again and now it works! Grrrrrrr.......ran some codes and the only one related to this I could find is B0249 - Heater/Defrost/AC Door Range Error. Is this gonna empty my wallet at the dealer? Thanks in advance for any advice. "Capital punishment means never having to say, "You again"? Link to comment Share on other sites More sharing options...

No promise this can or will resolve your problem but it has to be worth a try. With the engine at idle in PARK, slowly cycle the HVAC control MODE selector through all the possible positions from AUTO to the other four options. It's possible the heater/defrost/AC door actuator is simply out of sync with the controller and the above exercise might correct the problem. Jim Drive your car. Use your cell phone. CHOOSE ONE !

KHE Posted September 18, 2009 Report Share Posted September 18, 2009 Try the suggestion Jim mentioned first - it may solve the problem. If not, it is possible the actuator has some stripped gears in it which would require replacement of the actuator. It will be a fairly pricy part but it shouldn't be too difficult to install yourself.

It blows out of the bottom and top regardless of what mode I set it to. "Capital punishment means never having to say, "You again"? Link to comment Share on other sites More sharing options...

I can't say for certain because I have not worked on one of the 2000+ Devilles but the older cars had actuators that were accessible by removing the hush panel under the dash and behind the glove box.
