Chas3 is correct about the wiper balde and for the Homelink transmitter, 1 and 3 should clear the code, but sometimes mine does the same thing. I just hold it for 20 to 30 seconds and then give it a go. Now sometimes, with the new garage door openers, they have a rolling code. To set that up, you need to hit the learn button on the opener its self and then press one of the Homelink buttons and the remote transmitter at the same time and see if that goes.
