did you find the problem. i have the exact same problem with the 3 first codes and the cruise control switch
i hope you do not have the exact same problem !
for me it ended up finding out the car had been badly repaired after an accident and part of the air con was missing and the cruise control unit missing also. among many other problem .. i ended up selling it cheap to cut my losses
