Was diagnosing my HVAC system and got trouble codes 21 and 24. What does that mean?
dude y did u start a new thread on the codes instead of keeping it in the original post?
btw codes 21 and 24 are solar sensor codes, meaning you did this at night, in the garage or whatever and there wasnt enough light on the sensors. ignore those codes
i told you in your other post, servos dont show a code
