With headlight switch on all other lights work - tail, interior, etc. The Hi beams do work if the turn signal is held back - but headlights do not work if the turn signal lever is left in lo or hi. Saw another question with same symptoms - and he resolved it with a new light switch. I hate to spend $100 + if that is not the cause. Other possibility may be turn signal multifunction switch - anyone have any input?

I checked all of the fuses and they are OK. I do have a wiring diag and am going to pull the light switch to see if the red yellow wire is getting power (it powers Hi & Lo except when the i beam flash is used via the turn signal which from what I understand is a separate power supply from the light switch. If this was a failure of the light switch - it would have all of these symptoms - no Hi or LO but Hi works when turn signal lver pulled back.
Am I on te right track - KARTZAN41?
The Haynes book does not show details of what each plug supplies out of the light switch but I am assuming that several of these wires that are going to the functioning components - interior etc., are off of different poles on the switch which means the switch is getting power - and only th line to the normal scource of the Hi Lo beam is dead - correct?
Thanks agan for any info -

If the flash function works, but the headlights do not, it is almost certain that the problem is in the multifunction switch! I would replace it and that should solve your problem

the hayes books are junk when it comes to electrical.... only facotry or pro level service manuals are abou tthe only way sometimes.
I'd do what Bartzan say and check with a three dollar test light... but my guess is the multifunction switch has internal issues to it... I've seen the contacts internally go bad causing the issue you describe... I figure the high and low bean fues and such are working as flash to pass works both high and low beam lights...
Almost every concern I've seen can be traced to either the turn signal swtich or the wiring behind it..... I've beat on a few of those switches and got them to work for a second to diagnose them

replace the switch, the contact for the head light is bad. there are several wires going to the head light switch. when switching from low to high the internals of the switch moves the contact from the low output to the high output. if the power to the low contact is not working then you have no haed lights.

If you really want to pinpoint the problem cheaply, get a 3 dollar test light and send me your e-mail address. I will send you the wiring diagram for you headlight circuit, and tell you what to test.

have you checked the wiring? made sure that none of the wires are stripped or frayed away from the connection point? we had the same problem in our civic and all it took was a new connection to the light

Burnt fuse or relay.
There are 2 fuse boxes, so check them both.
