A/C blows on high when car is going up hills and is passing

Can you get a video of this? I just want to try and understand if the blower is actually changing speed or is there just more air coming through the vents? Clearly the blower motor has nothing to do with the speed of the engine but the acceleration of the vehicle could force more air in. However, you would think this would remain consistent with the increased speed. This is why seeing it will help get us on the same page.

As it stands, based on this information I can only assume that with the raise in RPM the alternator spins faster and sends more voltage to the blower. Kind of like a power surge but this doesn't really make sense because there are multiple redundancies and the speed control of the blower motor is controlled by the HVAC control module and not directly tied to battery voltage.

Let's get the video and go from there. Thanks

Okay. That is interesting. I can only assume this is related to the resistor but let's start with the video just so we are on the same page.

Also, can you try to get the part number of the resistor that you had replaced? I just want to make sure we are talking about the same part. Thanks
