Hi Cre , Thanks! , The motor was removed and tested across the battery both ways and works but always resets to " cold air " - air con position every time I reconnect to the harness and will not respond to any dash commands to move at all . The dash buttons and heat slider were removed and bench tested and all work .
My car is a ( UK ) Mk3 MA70 7mgte Auto registered 1989 .I can only get heat by leaving the door open manually with the motor connected to the harness but away from it's mounting .Any ideas anyone ? Thanks ! .
