Electrical questions


Recommended Posts

Hello everyone couple electrical questions. Have my truck running, idling and moving without overheating which is good. However, when I tested my blinkers I noticed that regardless of which one I tried both lenses lit up in back as if the hazards were on. Now on my dash I have following switch. What is it and does it have anything to do with blinkers? Incidentally it is always lit up regardless of position. Also the light above the bed is always on

That is the cargo lamp switch. You can unplug the connection from the back of the switch of the switch to deactivate the cargo lamp if the switch no longer works. As for the blinkers, this is a pretty common occurrence and tends to be either a bad socket or bulb though it can have other causes. If you turn on your hazard lights do they all flash as they should? .

It's an 88 with 4.0, haven't checked manual yet and for some inexplicable reason I didn't check the hazard button. Will tomorrow. Also, cargo light meaning the bed light on back of cab?
