Are there any videos to the installation of the interior headlight switch of a 1990+ Ford Explorer xlt years and removal of the old part?

At this time we do not have any videos showing the installation of the headlight switch.

I found videos on YouTube for f150 light switch for this years. Idk if it’s the same dash tho.

I saved this video for future reference. The Explorer shouldnt be much different from the F-350. Go to YouTube and search, "Replacing Our Ford Trucks Intermittent Headlight Switch" by Love Your RV (sorry, but this wont let me include the link). I hope it helps.

Hello SGT H. -- I used a video on youtube for a full-size Bronco -- the 1st gen Explorer headlight switch is VERY similar. If you go to youtube and search for "93 Bronco headlight switch" the video will come up. You will have to take the bezel off the dash first, which he doesnt show in the video, but there are other vids out there for that (you start by removing the radio, which itself can be an adventure) Also remember that 88-92 Ford Ranger and possibly 86-90 Bronco II will be similar, so you can search for videos of those too. I am happy with my switch I got thru 1AA Auto, it has worked well for me so far. hope that helps you in the right direction
