Long time mechanics, your suggestions would be appreceated?

Multi- switch is on the steering column, very easy to replace. the screws to the column cover are just below the steering wheel.,

remove about 4 screws ,seperate the plastic covers ,take a 15mm or 20 mm torx driver to remove the switch

That's it............

if you have any accessories hooked up to the wrong hot wire it can short things like that out , or the lights can be overloaded i would go to a scrap yard and get another light harnes and if you feel like fixing it yourself buy some 16 gauge wire and switches and make it to where you can switch the lights on or park lights on or both

The multi function switch is your turn signal / highbeam/low beam switch on your steering column. it is the problem, I had a 96 ranger that the headlights would just go out wiggling the switch would eventually bring them back on.

some are in behind the steering wheel and some are under the dash along the steering colum it is a little square box with a lot of wires coming out of it

The multi function switch is the hi/low beam-turn signal switch.

buy a Chilton Manuel it will give you wiring diagrams.

its behind your steering wheel, remove steering wheel and replace entire unit,
