Apparently I need a blend door as I have some heat but it's very little. When I change the temperature all the way to cold the little heat I have does change to cold so apparently the actuator is working.
The problem is that Rockauto.com lists two blend doors, both for manual systems. However I have an EATC system in my 99 Limited. Is there really a difference in the two? I've searched through almost all the threads on blend door but can't seem to find mention of this problem. If there is a difference does anyone no where to get a door for the automatic system?

Thanks in advance for any help.
