hi, can anyone tell me how to check a headlight switch on a 94 1500? thank you

 

Pull the bezel, pull the switch, have a look at the wiring behind it as well. Do your headlights not work?

 

they just quit working all of a sudden. park lights work, insides do too, fuses good need to know how to check switch thanks

 

Probably the wiring behind the switch, or, the multi-function switch on the column.... (turn signal/dimmer switch, etc.) Try tilting your wheel all the way down, and see if they work.

 

ok, heyyou, thanks buddy, i`ll check it out and update you

 

To check the switch you'll need an ohmeter. Just check that there is low resistance between the input terminal ('B1') and output terminal ('H') when the switch is pulled out (headlights on) and should be high resistance otherwise.

The wiring diagrams also show that you may want to also test B2 to I. They also seem to work with your headlights.

 

grox, i`m not real familiar with an ohmeter but when i tested like you said it goes from 1 .0 to 00.0

 

is that low resistance? thanks

 

I don't know about the resistance but when something like that goes bad in my truck I try tapping it and so far it's fixed my headlight switch and blower motor, the problem is probably in the switch. A thread just got bumped where a guy with a van had to clean his, I just tapped mine with the switch pulled out and got the lights on but later the switch started to melt the connector and had to replace. Since its easy to get to I'd start by looking at that if adjusting your colum doesn't find the problem

 

ok p1nkst@ff, thanks buddy
