Unable to control A/C temperature
I'm thankful that my A/C is working, BUT I am unable to control the temperature. It doesn't matter whether I set it to 65, 75 or 85, it always blows very cold air.
Even with the vents redirected, it gets so cold that I have to turn off the A/C, then back on when it gets too hot in the car.
Any thoughts on what might be wrong with it, or what I might check?
Thanks!

Cwatx,
There are many threads about the air mix servo. Here is a valuable one for locating and removing the servo.

Before buying a new servo, you might be able to fix the one you have. Most often the grease inside has gotten contaminated and shorts the contacts. You may be able to take it apart, remove the dirty grease, and regrease with excess grease that is in the servo.
This thread has photos of the grease cleaning.

I finally got around to swapping out my air mix servo last week. After freezing my *** off on a 2 hour car trip with no heat, it was time!
Thanks to everyone here for the excellent advice, and for the those who have posted to the threads that show DIY with pics - those were extremely helpful.
As others have mentioned, the hardest part was accessing the screw located behind the pipes. Other than that, it was very easy.
