Headlights aren't working.

[Don F]

First thing. Thank You to the forum and all it's members for your help.

I have a Canadian 1997 Aerostar XLT I've owned for 2 yrs now. Put some money into her and she's running great, except both my headlights just stopped working for some reason at the same time. No DTRL, no regular headlights, no stay on high beams just passing beams. All other lights work fine. I have searched the forums but can't find the fix.

1: I have changed out the light switch. No burns showing on the old one. No luck.
2: I changed out the Multifunction switch also. I have the auto dimmer model. Got my stay on high beams back from this fix, but no regular beams or DTRL.
3: Unplugged the Day Time Running Light module, no luck. I haven't replaced this yet as I'll have to pick one up at the bone yard.
4: Fuzes are all good.
5: Auto Dimmer ?

I'm at my wits end. Help !

Welcome to this forum! Here's a schematic diagram from my 1997 Ford CD:

Thank You.
The schematic will help lots.

I'm still looking for a DTRL module from the Bone Yard as I'm sure this is my next step before looking for a wire short.
