weird grinding/scratching noise from behind dashboard

[peppelepugh]

So it seems i tend to hear some weird Grinding/scratching/gear clicking noise behind my gauge cluster every now and again when the car isn't moving and radio is down. (i swear i can hear anything out of the ordinary on this car sometimes).

it goes for half a second with a little intensity at the beginning. then stops shortly. almost like a servo motor being twisted by hand?

I tooled around with the climate control and i think i've got it narrowed down to  my defroster? I notice if i kill all climate control, it stops, if i have it set on blowing out of the vents... nothing... set it to defrost, it starts to happen.

I won't be able to get a sound recording until thanksgiving time due to work travels ATM.

Thanks all in advance!

Blend door or climate control module would be first & foremost guesses.  There might be a TSB relating to the CCM, will have to check.

Wonder if the cold has a factor in being able to hear this now?

Blend door actuator motor. There's 2 of them. One behind glove box (the easy one to change) and one more towards the middle of the dash. (Pita to change)

Murphy's Law states that the one i need to change is in the middle of the dash!!!! haha

Thanks Glock!

I'll probably order one off Rock Auto and have me a project over thanksgiving. If i'm changing one, might as well change both you think?

Also, BEFORE I GOOGLE IT, anyone know of any write ups for the one behind the dash board?

I just need to figure out if its part number:
MOTORCRAFT Part # YH1779
OR
MOTORCRAFT Part # YH1769

YH1779 (AA5Z-19E616-C) is the glove box one:

I believe the OEM part number for YH1769 is AA5Z-19E616-A.  Pics courtesy of Tasca here:

Welp, I think the motor is on its last leg. Defrost only worked on half of the car on Saturday and then today the mix of hot and cold blowing on me when car was at operation temp.... well it was annoying.

I plan on replacing them all since its winter and I'm not dealing with being cold (i just got back from warm vacation... so i'm still grumpy about this 16* weather as i always am when i get home)

I'm looking at replacing parts 9, 10, and 11:

And just getting the parts off rock auto:
