1989 Toyota Truck....With the switch in the off postion my park lights are still on. The relay checks out so would this be the combination switch causing the problem. Are they easy to replace. Will the steering wheel have to be removed.
Found the problem. Had to replace the combination switch and it works just fine now. Seems when the switches get older they can build up a residue from the brass contacts and arc over causing the park lights to come on by themselves.
