so, you're saying that i'm not supposed to be able to turn off the defrost button manually? (it only shuts off when i turn off the jeep or by the timer)
in regards to the wiper, that's what i thought after i posted..but, i went to the jeep, took the arm off, verified the shaft is turning and the spline looks good. it does go back and forth ok. i took a look at the spline inside the arm..looks good as well..put it back on turned it on, motor tries to move it but can't move it more than about an 1/8 of an inch, unless, i lift the arm a bit? is that simply a weak motor? problem with wiring? i should note that the guy said the park circuit for it isn't working and i need a new switch really..(for 28 bucks, i'll get one if needed) but, the park circuit wouldn't affect the blade movement, would it? it seems to me the motor must be weak if the friction against the glass seems to stop the arm from moving?
