When the climate control panel is out of the dash everything is adjustable; temperature, fan speed, etc. When the control is set into the dash all control fictions are not adjustable. It is a harness connection issue with that grey plug circled by one of the earlier posters. What is the issue with that connection to have constant control of the panel? I do not have voltage testing equipment, besides the adjustable function is it not at the panel once it is in the dash. Someone give accurate answer please.

Hello,

It sounds like you have a bad connection at the plug, I would start by enhancing the terminals by using a small pick and force the middle of the terminal downward to create more tension on the connector.

Please let us know what happens.

Cheers, Ken
