Bad fuse, bad relay, bad bulb
Or Head Light Switch.
How do i kniw if the headlight switch is bad? It seems to be working. When i turn it to on, i get the door chime...also, when i flash my high beams, the little blue icon lights up but still no actual lights.
The high beam bulbs i literally just bought. I dont see how they could all go bad at once. What relay should i be looking at on a 2010 f150?
What I do first is to check all the fuses and relays.If they check out o.k. I then will look at the switch.
If everything else checks out the only part left is the headlight switch or a bad wire, which can be checked by a voltmeter prior to switch replacement. May need to get a wiring diagram some site offer downloads for diagrams and other for a small fee. Relay should be in fuse box under hood and you may need a tester to buy a replacement to check if its the issue or not and if not return it. I found one video on the bezel removal at headlight switch but it does not show much nor does it show the removal of the switch. A repair manual would be helpful if needed. I will go ahead and post the url. for the video in-case it may help out. Just copy& paste to new browser window.
Thanks so much for all the info. I appreciate that. Fixed it. Was a bad connection and 1 bad prong on the connector. Back in business.....for now
