Please explain used to work. What do you mean by Neither Do? Do you mean one light quit then then the other quit or they both just stopped lighting up.?Originally Posted by flyin2
For the latter, check fuse 15.
If you pull the stalk switch back (flash to pass) do you have all 4 lights or not?

Dennis,
Start with the high beam fuse 15. It's a 20 amp. If it is blown then it's likely a symptom of another issue.
Next check the high beam relay.

Note that the link above has the correct fuse numbers. The attached file below has the fuse numbers reversed, but I couldn't find a way in edit mode to delete the attachment.

Fuse #15 can have heat issues in the fuse box so check for that.
I found that mine had this issue last fall. I think was do to corrosion of the fuses. So yup a fuse box replacement is in my future.

Ron,
Perhaps you meant to direct your response too the OP.
I mentioned Fuse 15 in my first post,but wanted clarification to a couple things from the OP before adding additional diagnostic info.

Dennis,
Yes, my response was for the OP. One of those things where we both responded almost simultaneously. I thought I was the first response. But you were just a little faster. I scrolled up and mistook your signature for the originating post. At least great minds plow the same row

Do you hear the relays clicking? Also check that the high beam filament in BOTH headlights are not burned out. The bulbs with 3 brass terminals have a low beam and a high beam filament and one or the other (and sometimes both) can be burned out. One terminals is the common and each of the other terminals is the other end of each filament.

When I bought my car several years ago, the high beams didn't work. I could hear the relay clicking when I turned them on but no lamps. I ended up replacing the headlight switch with the DMCH repro modified system and this resolved my issue. As a result, I deduced my original headlight switch was bad.

It is now fixed. I re seated the fuses and it started working.
