Another DRL/High beam not working thread

[REDrum]

So my high beams and DRL went the other night. One shift to from low to hight and gone. Blue light on dash still glows, but nuthin. Just lows.

I have search quite a bit and all symptoms point to blown hi beam relay (baby blue relay in fuse box) and/or relay control block (near air intake box).

So I swap them both of the above out, and still no high's or DRLs.

All connections look good, but have not done any continuity check-out (yet). Since its been averaging 15F outside and don't have heated garage, I've hoping I can just throw components at it, and not have to deal with point to point check....

Any other ideas or experience welcome.

Thnx!

Check your high beam bulbs. DRL's will not come on if one high beam bulb is burned out since the DRL circuit puts both high beam bulbs in series. That's how it works. Maybe one ouf your high beam bulbs was burned out for a while and you did not notice it and now maybe the other one blew out too so now you have no high beams -or- DRL's.
Ask me how I know.
Good luck!

You didn't mention checking the fuses. You checked them out, correct?
