Hi beams won't turn off

If my wife uses the hi-beams on her 1993 245, they won't turn off. Is
this likely to be a relay problem? And if so, is it like the tendency
for the OD relay solder joints to fail?

 

I would check the stalk switch first, the other place to look is the metal
relay under the hood, I don't believe it has a soldered circuit board
inside.

 

Thanks. The Haynes diagrams made it look like the relay was in the dash
near the OD relay. It's actually under the hood?

 

My 90 has the same style stalk and I had the same problem. If putting the
lever into a turn position and then dimming the lights works fix as follows.

Access the mounting screws for the turn/headlight stalk system. Remove the
lower screw of the stalk mount and loosen the top screw enough to put one
washer between the lower mounting base and the column, reinstalling the
screw and tightening both back up starting with the lower screw first.

This twists the case enough to allow the headlight contacts inside the
system to always make contact.

There's a metal cased relay (also with no circuit board) behind the dash
which supplies power to the headlights, but the high/low changeover relay is
under the hood on the inner fender behind the battery.

 

Thanks for saving me buckets of time!
