The 20 blinks indicates an error in the ECC. Most likely is the cabin temp sensor is dirty and the miniature fan cannot turn. The sensor is located in the row of switches to the right of the steering column, it has a small grill opening.

You could try using a shop vac to suck dirt out of the grill. Or go the complicated route of pulling out the radio, pulling out the ECC unit, then reaching behind and taking out the sensor to give it a through cleaning. Just be very careful that you do not damage or bend the copper tube.

You could make your own code reader to retrieve the codes and clear them, but once the error is resolved the blinking lights will stay off.
