I have deleted my rear window defroster but am still using the switch for something else because it's fused and relayed. Problem: after 10/15 minutes it goes off, is it on a timer or what. Thanks in advance.

 

Yes, there is a timing circuit it is on to prevent the grid from burning out. Where it is, I don't know.

 

There is a relay in what looks like the rear passenger side of the car. Do you have a copy of the factory service manual? If so, I can direct you to a page that will get you close.

 

No I don't but I assume someone at my local dealership may came help me. I've had problems in the past with them not knowing very much about 350's. At least theres nothing wrong with. If I can get one I be in contact with you, Thanks.

 

BTW I'm running a rear Euro driving light with it so surely if I bypass the timer it should'nt hurt anything, it's only one 27watt bulb.
