I was out today getting my emissions tested (passed), and on the way home I noticed that my blinkers stopped working. I checked the forum, thought it was probably the flasher, paid $50 for one, and it did NOT fix the problem. I've checked inside and out, and cannot find any fuses for the blinkers (ARE THERE ANY?). My hazards DO work. All my lights DO work. No blinkers though. So is it the switch? Hope so. I already ordered one.
its the relay i have been battling the same issue randomly my blinkers stop working then fine the next day. i am on my third relay in a month. something else is happening electrically in these trucks besides the relays!!!
I just replaced the relay with a new one in the package. Still get nothing but hazards (but when the hazards are on you can hear the relay clicking). So, you know how you get that pissed off feeling when you buy a $50 part and it doesn't fix the problem?... gonna be twice as bad if my $80 part comes in Friday and doesn't fix the problem either.
Pdpunome, I'll let you know if this fixes it or not. You might have 3 perfectly good relays and 1 bad turn signal switch. S10's trucks and blazers were plagued by these switches going out all the time and the design is pretty much the same, so I'm crossing my fingers that this is it.
tried that theory as well i have three of those i keep swapping out trying different combos of switches and relays... same thing good for a week then bam all day no turns at all or just the left then good all others.
New switch installed... did NOT fix. Aggrevated. However, when clicking down the blinker, I DID notice that my AC/Heater made a quiet clunking noise. So I start messing with the AC/Heater controls and... nothing works (it was working BEFORE the blinkers started messing up). Aha. There's a short somewhere. I hate electricity. I don't even know where to start, but I guess I gotta go do it. Wish me luck.
ELECTRICAL GREMLIN FOUND. Even more aggrevated now that it's fixed because the problem was something I already checked. Fuse #20 (10 amp). The fuze is not blown. It's sort of blown. It looks like it started to blow or did blow, but then melted the lead back together. There's a connection there, but probably not enough to let the correct voltage through. I replaced the fuze and AC and blinkers work again.
Like I said, I had already pulled the fuse out and it looked fine. It wasn't until I looked at the other side of it that I could tell it wasn't right. So if anyones got an intermittant problem, check that #20.
