Installed nest thermostat in winter and heat worked great.  Now we turned on AC and it’s blowing hot. We have red green blue white wires only. Followed some of the troubleshooting from community posts.  Turned off breakers checked wires turned back on breaker reset thermostat (had to charge it). Put back thermostat turned on AC and still blowing hot. Pleaseeeee help we have 90 degree weather coming next week here in Michigan!! Thank you!

If you still have it, post a picture of the original thermostat's wiring. If you don't, post a picture of the wiring on the terminal block on the control board in the furnace/airhandler.
