Customer Question

I have a 2006 Lincoln LS, 3.9L. In the morning when I start the car I get a loud clicking noise that seems to be coming from behind (to the engine side, not to the rear) the right front tire. It goes away after about 15-30 seconds. Is there a blend door in that area that could be bad? Any ideas? Thanks.

Is the heater or ac acting up at all like not switching from hot to cold or different mode outputs when this occurs here?

Only does it upon start up. Once it's done it's thing for 15 seconds or so, it doesn't do it again. I can switch from heat to AC and or change fan speeds and or air positions and it doesn't matter it doesn't do it again after its initial clicking.

O.k.,this does sound like a fault with one of the heater box actuators clicking.This occurs when it doesnt know its stop positions when it has an internal electrical fault within it.In some cases you can have the fault codes checked using a scan tool that can communicate with all computers especially the heater/ac control on the dash to see what codes are set.Once this has been done if there is a code set for a particular actuator this is usually the actuator needing replaced.The noise would have to be coming from inside the dash area if it is an actuator.

The fresh air/recirculation actuator is one that is closest to the area you have described the noise coming from.In some cases you may have to examine the actuators when the noise is actually occuring to locate the one at fault needing replaced.
