After hours of searching this site and a couple others I've not been able to find the location of the HFL module. I can tell you where it is on TLs and 2007 and above MDXs, but not a 2006.

Can anyone tell me where it is located and if it is known the P/N?

I spoke to the folks at HFL and they suggested unplugging and replugging the module in hopes of solving my problem. They also said that a dealer could reset the system. I don't know if there is a way to do it myself.

All help is appreciated.

My problem is like that of others...no response from the HFL button on the steering wheel. When pulled nothing happens...doesn't mute the radio for commands.

Thank you....

 

It's the interior colored bezel that your overhead console lights snap into. Right where your windshield meets your headliner above the rear view mirror. I doubt unplugging and plugging it back in will make a difference, usually when they don't respond to input from the steering wheel control button, they are done. I would keep it unplugged regardless though because if it is bad, it can still pull an enormous draw on the battery even when the car is shut off.

 

Do to the kindness of strangers I've been able to successfully DIY my HFL issue.

Even though some weren't successful by simply unplugging and replugging the HFL unit, it worked for me.

I unplugged the HFL unit and ran the Nav diagnostics...it showed all systems ok (green) except the HFL (red). I turned off the vehicle and after 10 minutes I reconnected the HFL and started the engine and tried the talk button and it worked.

Of course when I tried to give it a command it didn't work because I hadn't yet connected the light/mic/on-star cluster. Once connected we were back in business.

Not having cash for repair of this type of luxury item I was pleased and grateful for the help and a working HFL.

Now if I could get the photo links to work for the rear AC transistor replacement I'll be set.

Thanks again.
