Hello, I have recently replaced a faulty blend door actuator under the dash of my sky, but I have recently heard a new loud and rapid ticking noise from under the dash. I traced the sound to this weird box covered in electrical tape.
116351

What is this thing, is it important, should I be concerned about the noise.
Any help would be appreciated.

Boy...I was just under there this morning, and don't recall seeing a bunch of wires bundled/taped like that. Wish I could answer your question.

I question both boxes. What is the box with the adjustment from MIN to MAX?
Mike, I think the blend door actuator is the HVAC temperature blending actuator.

There are three actuators in the HVAC system, so just calling it "the actuator" could be confusing.

Neither one of those items in the picture are the Stock HVAC Actuators though. Does anyone know if the Stock Actuators that are supposed to be under there, are all the same model number?

I'm pretty sure the box is a relay but I'm not sure what its for, ill just do the tried and true method of unplugging it and seeing what stops working.

Thought the box with the green knob was an aftermarket alarm, when I first saw it.
I think you are right, it says Electronic Security System on the other side, so I'm guessing the green knob changes the alarms sensitivity. it is not however connected the ticking black box directly.
