Lights + brake lights
I posted guestion forgot to mention . It's head lights ,running lights ,brake lights
and rear lights are out. Signal and flasher all work. Can't find short, fuse ok and
bulds ok. Need help!!!!
The diagram is for headlamp switch, red wire with white tracer at headlamp switch should be hot all the time. Use a test light to check for voltage. Is it hot?
Dodge ram 250 cargo van I want to remove the back light is born how we can open the switch ?
Did you ever find the problem with your lights ? My 89 B350 is doing the EXACT same thing yours was doing. EXACT same thing. Have found that when i push the brake pedal - Terminals B1 & B2 both lose power.
No Headlights, Park Lights, Brake Lights, Dash Lights, or Horn. If i push the brake pedal - or the Horn - B1 & B2 both lose power to them. This is with the headlight switch disconnected and taking readings from the plug/receptacle.
Solved ... Corrosion build up inside the bulkhead connector at firewall. Wire L1 (Red-White stripe) heavily compromised at the external terminal. You have to remove the exterior half of bulkhead from firewall - then roll up the rubber covering - to expose the external terminals to inspect. ...aka = long term water damage
