I just purchased a rebuilt climate control module. After reading I understand I drop the ash tray out, unscrew the two screw wich will release the module itself. After that, I don't know what to do. What conections do I have to make? Please help, as I don't have any heat. I have already replaced the Monovalve, and the Aux. Water pump. Thanks for the help.

As to the heat question, unplug the monovalve. Do you have heat? If not the problem isnot electrical. The valve will go full heat when disconnected.
