Pull head light switch and low beams don't work? Hit the high beams and they work fine? Put a new headlight switch and same results? Checked fuses on side of dash and under the hood. All was good. Did not see a fuse marked low beams or headlights? If theres a fusable link I didn't see it?
Headlights,Highbeams work,Lowbeams don't? on 2002 Dodge Ram Van 1500
I think I had researched a similar problem before and concluded the wiring had a problem with the "integrated power module" . The tests were easy once you had a wiring diagram and a good volt meter but of course you need a wiring diagram and component location chart which I have no easy way of sending to you. There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subrcription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try http://www.eautorepair.net/Marketing/Default.asp?VID=125669 and get an online repair manual subscription.
