I have a 1997 GMC Sonoma and just today the blinkers stoped working. I checked the fuses and are all fine and some how the hazzard lights work. The blinker switch gos on when I put the bilnker on but the light does not and after a turn It shuts off. If any one can help I will be very thankful.

Sounds like either the flasher for the turn signals are kaput (unlikely) or one of the bulbs is defective. The emergency lights have their own flasher. Sometimes water gets into the parking and taillights that causes them to corrode. Being that your emergency flashers work, turn them on and walk around checking for defective lights. Chances are that what ever the problem is its related to a bad ground, bad bulb receptacle, or burnt out bulb. Good luck.

HEY I WAS JUST WOUNDERING IF YOU FOUND OUT THE PROBLEM WITH YOUR SONOMA BECAUSE MY 1998 S-10 DOES THE SAME THING AND IVE BEEN TRYING TO FIGURE IT OUT FOR AT LEAST A YEAR NOW. IVE TOOK IT TO THE DEALER THEY COULDNT FIND A PROBLEM BECAUSE IT WOULNT DO IT TO THEM, IVE EVEN TAKEN IT TO ANOTHER SHOP AND IT WOULDNT DIE ON THEM EATHIER AND EVEN THOUGH THE VOLT METER WOULD DROP THEY SAID THE VOLTAGE WAS STILL GOOD. MINE WILL DO IT OFF AND ON IT WILL BE FINE FOR A COUPLE OF MONTHS THEN THE NEXT COUPLE IT STARTS ITS CRAP AGAIN. I HATE IT SO IF YOU FOUND OUT ANYTHING LET ME KNOW

I signed up for this website because of your post. I have a 98 S-10 2.2L with the identical problem. I've replaced the alternator, which seemed to work for a month or two because my volt meter held steady at 14 amps. But the problem is back with my meter usually reading about 13. Then occasionally it will begin to drop and even twitch when a turn signal is on, just like yours. Once it gets down to about 10-11 my electrical goes hay-wire and the truck dies out. My truck is a manual so I can put it in neutral, and restart it as I'm coasting down the road...and it will run fine. This may happen a few times in a day and then no problems for weeks!
Everybody I've talked to has of course told me that there's a short or loose ground somewhere. I've cleaned every connection and ground that I can get to. The only thing I haven't been able to really check is the starter because you have to remove the exhaust pipe to get to it on the 2.2L and those bolts are not coming off for me in my driveway. Have you had any luck figuring out your problem? Thanks.

I have a 99 2.2 Sonoma and I can drop the starter with out removing the down pipe.
Can't remember the exact procedure but it was easy. I think both support braces and the cross bracket.

Yesterday while backing out of driveway my AC/Fans quite working. In addition the radio/clock stopped. Clock/radio came back. Then fuel gauge/temp gauge went out. Back on this morning. yesterday the wipers/wash would not work. Still don't. Lights for what gear you are in are out. Come on briefly on start. Wipers/wash out. If radio is on and I swith on AC to see if it works radio goes out. What is going on?

My 98 S-10 (2.2L w/135K miles) also has a wandering dash voltmeter. I have cleaned, inspected, and replaced every ground connection, both visible and hidden. New battery, starter, and alternator haven't made any difference. The problem is unpredictable, has once put the battery light on, and even caused stalling under load. I have just purchased a $600 scanning tool and discovered that no codes are stored. The voltage data taken, while parked and driven, is what the ECM sees. The dash voltmeter is showing the actual reading, going into the computer, regardless of the battery terminal voltage. I am reading, at the ECM, 13.5V to 14.2V under normal conditions, then the slow decline begins and can drop to 11.9V. Then , without warning, go back up to the 13V+ range. My next step is to install a new ignition switch which I've just received. It is a scary looking 22 inch mass of 13 wires and four connectors. I'm still looking for a decent reference for installing it. Also, I just ordered, from the dealer, a full set of pos. and neg. battery cables for $216, including the 175 amp fuse for the cable junction block under the battery tray. Oh, and I have a good SW ammeter going into the circuit to compare to the voltage readings. I will report on the results after all the new stuff is installed. I'm convinced that this is an age/resistance/temperature problem that is affecting the charging system. Voltage doesn't just change unless current and/or resistance changes, too (Ohm's Law). I think we're all chasing symptoms, when the problem is an inadequate primary system that overwhelms the alternator and battery. I'm thinking a FOR SALE sign might be added to my list.

Your on the right track with the ignition switch, common problem on high time trucks. $216 for battery cables, oh my gosh, I would have bought aftermarket.
