Occasionally we hear clicking under the passenger side dash. It will stop when you press the brake though. Anyone know what components causes this behavior???

Thanks,
Mike

 

Is it a rapid clicking? Does it just start/stop randomly?

If either of the above I'm betting that you have a bad ground somewhere inside that feeds these relays.

And please put your year, make, model, engine/drivetrain in your signature and attach it to your posts to help us better help you.

 

It's a 1998 Jimmy with the 4.3 engine, 4wd, and automatic trans.

The clicking will start at random.

I hate to tell you this, but I had the same thing happen. I had to replace the entire turn signal/hazard switch. Luckily i found an AC Delco on ebay for $105. Which is about half price. Let me know I will give you the contact info.

 

I have the exact same problem. hazard-blinker relay is clicking but stops once I step on the brakes.

mdhokenson-

You say you had to replace the entire turn signal hazard switch?

Do you have the GM part number for this?

GM Part # 26100853 should be the correct application for any '96+ truck. RockAuto.com has it for $118 and GMPartsDirect.com has it for $126 (but their shipping is way overpriced and takes forever). I could probably get it locally at my AC Delco retail store for at or better than the GMPD.com price.

 

Yeah, I had to replace the entire turn signal switch. My flasher would click at random and I tried to replace just the flasher unit in the glove box, but that did not fix the problem. They normally run about $200-250, but I found a guy selling new Ac Delco turn signals for $105 on Ebay. I was very happy with the part and cost. I'm at work, but will post his name when I get home.

 

Do you know what part internal to the switch failed?

This is the turn signal switch or the hazard switch?

Look forward to your reply.

Best Regards, Brent.....

 

I believe that it was a relay switch within the turn signal/hazard assembly that was to blame. The name of the seller on ebay was conquestautomotive, just do a search for that seller. Let me know if you need anymore info!

 

Thank you much.

Looks like a pretty easy replacement for this switch assembly. I see it now that the turn signal and hazard assembly is 1 piece. I have the 1998 S/T Truck GM service manual (3 volumes of it) and is shows pretty well how this is done. Easy as pie -at least on paper...
