Hello. My name is ***** ***** I am happy to assist you today. Give me just a moment to review your post, and I'll be right back with the help you need.
Have you checked the blend door actuator for the driver side to be sure its working?
Are you working on a automatic system (buttons) or a Manuel system (knobs)?
Okay Are you able to check the signal to the actuator if I send you the steps>
No all you will need is a volt meter, See the steps in the link below. Run through them and see if this will help you determine the cause.https://dl.dropboxusercontent.com/u/104923897/LH%20blend%20Oct%2024.pdf
Okay run through them and see if this will help you get this resolved.
Well if your sure the module is okay then you likely are dealing with a wiring issue if you are doing your testing correctly.
See if the wiring diagram for the System will help you with the correct wires.https://dl.dropboxusercontent.com/u/104923897/Climate%20control%20Oct%2024.pdfhttps://dl.dropboxusercontent.com/u/104923897/Climate%20control%20%232%20Oct%2024.pdf
You can also ohm check the wire t check for an open as well.
The light blue wire should read reference voltage of about 5 volts plugged in from the module . If you checking it unplugged you will not get a reading.
Im here, I had to step out for a minute.
If its trying to work now then let hook everything back up and try running the Blend Door Actuator Calibration Procedure. See the steps to do this in the link below.https://dl.dropboxusercontent.com/u/104923897/Reset%20Oct%2024.pdf
Take a look at the link I just sent you and try running the Blend Door Actuator Calibration Procedure. This needs to be done anytime they are replaced.
If you checking it with it plugged in there there should be reference voltage , if there is not then it is possible the pin could be bad or the controller is not producing a signal.
Did you ever try the Blend Door Actuator Calibration Procedure I sent you this morning?
Well something is being over looked here but with out being there to do the testing my self Im not sure what it is. If you would like, I can open the post back up for you. I am out of ideas as well as things to check.
Your very welcome and thank you as well.
