Hello I have a 97 e450, when I turn my high beams on the indicator light comes on but no high beams. Does anyone know what it could be?
Thank you

 

Could be fuses for the high beams, could be the multifunction switch----an EVTM helps so much in this instances.

 

It's not the MFS since the cluster indicator works and it's in parallel with the main headlight high beam circuit. It's also not the fuse since the power for the indicator is tapped off after the fuse.

It's either a wiring fault or two bad bulbs. Get your meter or test light out and test the light green/black wire at each bulb to see if power is being delivered to the bulb socket.

 

Thank you everyone for the quick replies, I will test this weekend and I'll be back with my results. Thanks again

 

I tested the wires at the headlight and at first I tested voltage on low beams to make sure I had the right wire, then I turned the high beams on and at first they weren't on, when i tested for voltage it was around 13 volts, then I looked at the driver high beam and it was on, I'm not sure what's going on here. Now they are both working. Is there a relay that could be bad? Thank you everyone for all your help.

 

Could be the bulb sockets have become corroded and losing contact. Either clean or replace them, use a dab of dielectric grease on the contacts to prevent this in the future.

Dorman also make "high temperature" replacement sockets with a boot covering the bulb contacts, enclosing the connector inside a protective covering.

 

The high beams stopped working again for some reason, I'm not sure where to look now...

 

If the bulb socket was corroded that wouldn't make both of them go out, so it has to be something else

 

Go back and do the same checks as before.
