'99 blazer high beams won't work
My '99 Blazer LS high beams have stopped working. Originally the driver side high beam went out and I thought it was a bulb. Replaced the bulb and did not work. Checked the old bulb on the passenger high beam connnection and it worked fine. When I reconnected everything, both high beams are now out. Is there a separate switch or fuse anyone is aware of? I could not find a dedicated high beam fuse in the fuse box diagram. Thanks for any advice.

Should be in the fuse box under the hood labeled RTHDLP and LTHLP. Both are 10 amp fuses. Check them out and make sure they are working. Make sure the Headlamp Relay is working. Part of the relay could be bad. Also check the DRL relay.

If the above does not fix it, it could be the multi function switch, which is your turn signal lever on the left, cruise, wipers, high and low beams etc. Have been threads on that. What happened to me on 96 tahoe. Believe same part. Let me know if I can help.
Hope the other fixes it. Dave
