You need to fill in your user profile so that we know what year of car we are dealing with. But it is my guess that you need to clear the Diagnostic Trouble Codes-DTC's several times. Then make sure that your engine is running, outside, then try and complete the up and down cycle several times. It is very important that your battery be strong, that ALL of your limit switches are functioning, etc.
