Headlamp Check Valve

Postby bstone63 » Sat Nov 25, 2017 12:45 pm

I'm pretty sure I found out why my headlamps won't open. Instead of the check valve that is connected to the vac source, vac tank, and headlamp switch, there is just a regular tee fitting. Does anyone know of a replacement part? I can't find the GM 394420 anywhere.

Fixed!! 8-)

Bought a $5 check valve from a local parts store and they started to open. A couple of snips on the ends of a couple other vacuum lines and voila! Plus I now have heat as well.

Good deal!

Can you post a picture of the repair? Where was the valve? What year toro?
