Looking for the location of the door blend actuators. I have duel climate control, so there should be one on the drivers side which I can't seem to locate! I did locate the right side under the glove box.

Thank you! That should be helpful. Though I may be getting ahead of myself. It seems that the actuators are working, I can go through all the modes, defrost, front vent, floor and the combinations of them working together, but when I turn the fan to high or any position the air does not blow very hard, most notably the floor! Hardly at all ! I should note that I installed a new blower motor and changed the cabin air filter and a right hand door blend actuator not to long ago. Any thoughts on my problem?

So the fan seems to work properly except on the high setting? If so we need to suspect the resistor is the issue. However, let's go to the blower motor and check the power on all speed settings on pin A. The voltage should increase up to close to 12 volts as you increase the speed.

Let me know if you have questions. Thanks

Um. Well no, the fan speed is working properly on all setting. It just seems not to blow very hard on any of the settings, like something is restricting the air flow within the duct work of the system.

That's odd. Does the mode select work properly? Meaning when you select defrost, floor, etc, does it only blow out of that selection and not any of the others when they are not selected? If so, I still suspect we have a blower motor issue.

There is not much that would cause a restriction in the air box other then routing the air to the wrong area so I would still lean towards a weak blower motor.

Did this just happen one day or did you just buy it and it was doing this?
