I just wanted to add my experience with this for people to find. After searching like crazy to find out why I had cool air on the left, and warm air on the right, I figured I had to have a bad servo (after first making sure it was full of coolant of course). I took everything apart so I could watch them operate, and everything looked ok to me. Still people said, when in doubt, change all the servos, who cares if it costs $600, do them all or don't come back with questions. I didn't change mine, but finally decided to simply flush the heater core, and now I have all the heat again. I realize that the servos do go bad, but if they look to be working try the flush. It's free and might be all that is needed.

That user has one post from 2 years ago. Its unlikely he will reply at this point.
That said unless the car has a seperate heater core for the left and right sides, which it does NOT, there is no way a flush would resolve the issue of no heat or cold on one side or another.
I just changed all three servo's on my son's GS300. The more likely culpret if all servos are working but not adjusting the heat is that one of them is not connected to the adjustment arm of the air box.

Ironically that is the only one i did not have to change. From what i read it’s the easiest though.
The three on the passenger side i did change were a pain for my man hands. Had to cut a screwdriver in half to get it to fit. Use a super thin screwdriver to get to another.

I too was not getting heat on the driver side. I removed the servo, took it apart,cleaned the contacts and reinstalled it. Still no heat, it would not actuate to the changes in the temp button. Went to my local junk yard and took one off an 04 GS they had there for $10. The servo was in the up/max heat position. I got lucky caused it works as it should, no noises on start up.
In you case I suggest you take the servo off but leave the connector plugged in. Turn the car to the on position, change the temp settings from hot to cold and see if the actuator moves. If it does not move it is likely bad.
Good luck with it not fun driving with no heat.
