Low beams are not functioning properly. High beams work fine if I pull on the stalk, but they do not click into high and stay there. If I want the high-beam lights to work I have to hold the stalk. I only get hi-beams and if I let go I get nothing.The backstory: I was driving home from work this weekend and using my headlights on the Pacific Coast Highway. It was foggy in spots and the low beams were working fine, I think. At least they worked fine the night before... At one point I sped up for a pass and flashed my high-beams to indicate I was coming through. (It's a narrow road in most places.) As it was getting dark, I realized the low beams were not working. Any ideas on where to start? Multi-function switch on the column?98.5 QCSB 4x4 w/ 178k...Thx,bb

billy, what year is your truck? I know the 'old skool' style light switches (like my '96) were notorious for failing/melting/burning/firefirefire due to their inadequacy to handle the current draws, especially later in life. I replaced the one in my '96 and the harness plug was all melted looking. Ironically, the new switch came with a new harness connector as well. Coincidence? nah.. ;)
