Default Stuck on defrost
Need help. 2017 impala-standard climate controls. No matter which mode I push it’s stuck on defrost. Heat to cool works and fan speed works. I believe the upper most actuator controls the mode and all it does is pulse. Took it out and it doesn’t move. Replaced it with a new one, same result. Any suggestion? Thanks for your time. Also I did the evaporator core about 2 months ago and everything worked fine. Just started about 3 weeks ago
