Mode door actuator replaced. Performed reset. Worked for a few days and now back to defrost only. If I try reset the system it will work sometimes until I shut the van off then it defaults back to the defroster on next start up . Sometimes the reset doesn’t work and it stays on defrost. Any ideas? Rural mail vehicle in Florida so I need that A/c to blow on me every now and then haha

 

Did you use a scanner to re-calibrate it?
