wildebill308 Report post Posted September 1, 2021 Welcome to the forum. Try this, turn the AC off then turn the thermostat off. Remove the front cover on the thermostat and remove the fuse inside. Check the fuse to make shure it is good, then re install it. replace the front cover and turn it on. Try your AC settings and see if they work. Bill Share this post Link to post Share on other sites
