Trying to figure out what wires should be hot and at what time. Book I have doesnt show much for wiring on it. Had four wires hot with a test light then I have two and one real dim. Fuse is good. Tried different relay and switch. The little light dont come on. Turning on the headlight the other light will come on n I know which wire that is. It is the only swith on that plug. Thanks

You have a damaged grid. They sell a repair kit. But its only for small repairs. Replacing the glass is your only option

So with the key in the run position and you press the defroster button it doesnt light up?Have you tried unplugging the chime module and plugging it back in?

So unplug the chime module and plug it back in and see if everything works make sure the module is fully seated. Let me know if that fixes it.

Pulling chime did nothing. The wiring in the plug for switck left to right is yellow pink light blue then to the right side is black white brown green brown. Key off pink has power. Key on pink is dim, white is dim, brown has full power. The brown to the far right is on with headlights. Pushing on the switch n checking it doesnt change anything.

Check all these wires with the switch unplugged. Brown should have power with the key in the run position. The black wire should have 2 ohms or less to ground. With the switch plugged in and the key in the run position turning the switch on the light blue wire should have 2 ohms or less to ground.
