Its very easy to change.... or just clean it.
The actuator is right next to your knee or ankle...
Take off the bottom plastic panal and the lower steering column plastic. There will 3 screws holding on the actuator. Top left one will be covered in a wire bundle, just move aside. The top right is easy. The bottom right is harder for sure, long screw driver.... and then the wire connector is easy.
After out, you can pull the actuator apart, little plastic tabs, that you will break hold the thing together... open it up and clean the whole thing with rubbing alcohol. The grease screws with the pot in there. Then put it back together. I had to use some superglue.
Plug it in, then run the heater and ac controls and you should feel it move.... then reinstall.
After I did mine, it lasted a few days, long enough to amazon me a new for less then 30$. I replaced the old one in 25 mins, in the street, in the dark.... worked great so far, a month now....
