Replace The Wiper Blades on a Sonoma, Jimmy, S-10 and Blazer

This article is visible to only you.

Here's all the parts, tools, and instructions you'll need to change wiper blades on any 1st generation S-Series truck.

This includes 1982–1993:

  • GMC Sonoma
  • GMC Jimmy
  • GMC Syclone
  • GMC Typhoon
  • Chevrolet S-10
  • Chevrolet Blazer
  • Oldsmobile Bravada

These trucks use a side-pin style mount that is usually available in just about any aftermarket wiper blade.

I suggest using the modern beam style wiper blades (like the Bosch 16-CA Wiper Blades I bought), though there's nothing wrong with the older frame style.

Grab A Soft Rag or Towel

1

The wiper arms will just slap against the windshield, so grab a soft, cushiony towel to make sure you don't scratch or crack the windshield accidentally.

Remove the Old Wiper Blades

2

Every brand of wiper blade has a different mounting system. Figure out what tabs you have to press or release to remove them.

The Anco brand blades I was removing had this flat tab that needs to be pressed down.

With your towel in place, pull the wiper blade away from the arm.

Make sure to supporting the wiper arm itself so your not just yanking it around.

The side-pin mount has a big tip, skinny middle, and big base.

This design allows the wiper blade to lock into place in the center recess. As long as the clip is unlocked, it will pull off. I had to fight with mine a bit to get the large tip all the way out of the wiper blade.

Install the New Wiper Blade

4

If your wiper blade has a locking mechanism, open it for installation.

The Bosch Clear Advantage blades have a hinged locking cover that simple opens like shown below.

Slide the new wiper blade onto the wiper arm. It should simple slide on, make sure it's seated all the way in.

Finally, make sure the wiper blade's locking mechanism is engaged.

All done, I really like the newer beam style wipers!
