What is your question?
Cannot change any function with A/C/ Heat. Replaced the in dashA/C Heat control with no change. Is there a relay or anything that can be checked?

you can use a scan tool to see what codes are in the a/c control unit. your new control unit won't work until it is programmed to your car. there is not much software other than OEM Volvo that will work on this.
