I've read as many of the FAQs concerning this as I can stand and for once I'm more confused than when I started. The rear defog switch on my 86 240 apparently has a mind of its own. First time I used the defog switch (momentary no click)it turned on but wouldn't turn off till I stopped the motor and killed the power to it. Later on I had limited success in flicking the switch till it turned off.
So I replaced the momentary switch with a regular on/click of/click switch from the Ecology Center. No change in attitude. Obviously I've missed something. Should there be a time delay in the switch or can I replace it with one that turns off when I tell it to?
