Works when it wants 2 but mostly just reads failure, any advice would be appreciated thanks.

you probably have ONE sensor that isnt sealed right, are you noticing that it works after like 5 consecutive days of sunshine but then after you wash it or there is condensation on your windshield it doesnt? mine has the same symptoms and when i get around to it im going to remove the sensor, cover the whole thing in silicon sealant and reinstall - if that doesnt work im buying a new sensor but again - havent had the time. The way to diagnose which sensor is bad is to start the car, engage PDC and then walk around the car and "listen" to each sensor the one(s) that isnt(arent) clicking are either broken or have moisture inside them (if they are flat our broke the PDC will never work, my guess is a bad seal though because once in a while it works right?)
