You can start from checking all fuses and relays, and loose wires that might be the cause of root problem. If not then you can dig into checking the cruise control cable or suction part in specific.
Super glue indeed is very good, you can clean both surface nicely and re apply super glue. After apply make sure to hold it in same place for 2 minutes with little pressure on it. Secondly fix it in night and then don't drive for next few hours, so that by next day morning it will be permanent fix forever.
