I turned headlights on this morning on my 99 2500 and the dims wouldn't work just the brights. Any help would be appreciated. thanks Jr.

 

Do you have access to a multi meter & familiar with using ?
Unplug the head lights , check continuity of the filaments in the head lights , then see if power is getting to the low beam .
After that it could be the switch in steering column , do a search here , for wiring diagrams , to find you specific truck , someone should know that model & give more info soon .

 

Disconnect the batteries and spray electronic cleaner at the base of the multifunction switch (turn signal) while working the dim/brights back and forth.

 

thanks for the info. found another thread with some info too. thanks again
