Doing one of these soon and can't remember having ever worked on one before... Anything I should watch out for?
thank you-

Piece of cake just make sure the rain sensor is working prior to beginning the work. Sometimes when you replace them it is necessary to recalibrate afterwards. I ran into the problem of sensor not working prior to doing the work. And had to eat the cost of fixing it for the customer because error on my part for not checking.
