I am not sure if the 91 is exactly like my 92, but there is 4 screws that hold the dash plate in place. Remove that. Then you will see two wire assemblies on the left side. One for the dome light and the other for the headlight switch. There is tabs that hold the switch in place via a mounting bracket that is screwed into the dash plate. It also has 4 screws. Unplug the wire assembly. Be careful not to use too much force because you can end up ripping the contacts out. There is a plastic tab that you will need to apply pressure to before the headlight switch will come out. The process is rather easy. The trick is to be patient and not use too much pressure because these are plastic parts and they break very easily. After you get it apart the new headlight switch will just clamp right into place. Reassemble and you are done!
Hope that helps and makes sense.

I need to know how to install a headlight swith in a 1991 ford ranger xlt
Typically this is a failure of the headlight switch assembly. See the question about how to replace the headlight switch in a 1991 Cherokee for the answer of how to accomplish.
The headlight switch should be easily removed from the dash. There are two connectors on the back side of the switch (one for the headlights and one for the dimmer). Simply unpug the connectors and plug in the new switch.
Just the bulb.
There isn't one. The headlight switch has a circuit breaker built into it.
There isn't one. the headlight wiper system will come on if the headlights are on and you hit the windshield washer button.
You may have to replace the headlight switch since your tail lights are tied into the same switch.
Headlamp switch contacts need adjusting switch has 5 contacts,
no. try replacing the headlight switch... eBay
You remove grill to remove and replace the headlights.
unplug the bulb, then remove the metal clips on front of headlight that secure it to the grill. pull the headlight straight out of the front of the grill. This is the best way to change the bulb as well.
Turn the stupid headlight switch off. DeeDeeDee I have the same problem with my 87 Camry. You need to change the stop light switch.
