Parking lights in front stopped working. Both turn signals flash when you use turn signal no horn. Turn signals work as they should in rear. 98 blazer 4.3 185k. Head lights work brake lights work.

First thing to check is the front parking lights fuse in the UBEC. Then try 2 new bulbs.

It could be the parking lamp relay? Book says it's located behind the fuse panel (under the left side of dash). Diagram is from an 01...so 98 might be similar. Also check the PARKLP 20A fuse. That should be for the parking lamp relay as well as a grounding relay for the headlights. But the headlights work so the fuse may not be bad. Let us know if you find anything.

That Body Relay Block is up behind the headlight switch. You need to drop the hush panel at the bottom of the dash and reach way up in there to get it out.

I had the same issue, but it turned out to be the fuse itself wasn't making full contact with the fuse box. Have you tried wiggling the fuse to see if they flicker on?
