Anyone replace this?
My left three vents blow warm/hot while right side vents blow cold.
Recently had new compressor installed and system checked.
Leaning towards this part for a fix.
Thanks

Great. The write up sounds easy though...lol
No point in spending $600 on a/c repair if it still blows
warm. I need to fix this part.

Finally installed new actuator after it collected dust on the shipping box for two months.
Well I still have the heat blowing out the left three vents.
Perfectly cold and fine on right two vents.
Not 100% sure I install correctly. Went on the shaft fine.
The shaft rotates 90%. So I'm not sure if I need to have it 90% rotated and try again.
Anyhow. It's hot and I got a new compressor I'd like to be using.
Any help would be appreciated.
Thanks

I feel for ya because I don't know of an easy way of getting those actuators out. I took a couple out of a junker and it was a major PIA but maybe the instructions help?

My problem has been the cold air will stop blowing out of the vents but I think I've narrowed it down to being low on freon. Last year we added some to it and it worked well throughout for the year but come this year I believe it leaked some back out so I added some more. I need to get a guy test it for leaks before it gets really bad!

I hope you're able to get your problem fixed though. Do you have digital dual climate control or the other one? Maybe the unit is bad?

Hello, If you have the dual climate control then you may have two actuators. I have the single so All my vents were blowing hot, so I manually turned the shaft with a nail on the end, it blew cold so I knew what my problem was before removing the actuator. I was really pissed because it was hot, I'm really lovin that cold air now. Try the other side and Good Luck.

GTPJack, what do you mean the other side?
Thanks

What makes it dual?
I have the two lever one, where one can adjust temp on driver side
Or passenger side.

Herc, that's just early years (digital dual, my '98 has it). Around '00 they switched to manual dual climate and got rid of the digital completely.

I'm not sure where it's at, but there should be two. One that changes the temp of the air separately for the passenger.

I'm guessing you'd have two because it worked for you after you changed the one on the driver's side. When I was buying my actuator, I was at the dealer and I remember him saying that the dual climate where you have a separate control for each side has two actuators. Go to the dealer and they can print out a digram and show you where it is.

Thanks BlackArrow.
According to that, there is a bunch of actuators and controls.
