I had a new AC solutions unit installed and its been working wonderfully until today. Now is blows only hot air. I have checked the fuses in the fuse box. The front SPAL fan doesnt turn on anymore and the blue button light doesnt turn on but the recirculation button light turns on. I swapped the bulbs and they both work. Could my button have gone bad? How would i check if it is ?

Any other trouble shooting ideas would be great. thanks
