Blendoor actuator on passenger side

I do not see a left and right blend door actuator listed. Is this a 1500 Sierra? The part number will be right on the part I use those numbers to help find the correct aftermarket parts as well. The aftermarket parts will say it replaces a certain factory part number.

Yes, but at advance the description says driver side.

That is what I show on rock auto dot com for descriptions.Honestly your best bet would be to get the part number on the actuator itself. That is what I would do from seeing the descriptions with lack of listing a passenger side one .

Is the part called lower blend door actuator or main blend door actuator?

On those trucks usually the lower one in the middle is the drivers side blend door actuator.I do not see how a main blend door actuator could ever be referred to the passenger side one. I cannot read the part number on that label can you read it to me?

It is worn off, I cannot either.

I got the part. thanks for your assistance.

You are welcome. glad you found it.
