I have a 2005 Escape Hybrid, new to me. Wrench light and \\\"Service soon\\\" message is coming on intermittently, turns off when I restart. Usually goes away with a restart. Does not seem to change drivability. Seems to happen more on warm days. Changed the blend door actuator, did not seem to make a difference. Looks like coolant is flowing in the hybrid cooling reservoir. Sounds like battery fans running when I open the battery filter door and remove filter. Took it to Ford Dealer to read code when light is lit, no code. The \\\"hybrid guy\\\" was not there so they did not check the codes in the hybrid system, so I would have to bring this back. Any suggestions about what it could be? I am thinking of buying another blend door actuator and changing that again in case I got a bad one. Any other ideas?
