Change windshield wiper blades on a 2001 blazer

I don't know if your trying to get the wiper arm off or just the refill? If your trying to wiper arm off, there usually a small clip that you pry out to remove arm.
If you just talking about refill blade, I don't know w/o looking at it? Your local auto store might replace the refill blade for you, where applicable?

20 inch and all the auto parts store will install them for free after you buy them, so let them do it!

I have the same problem with a 2001 Legacy wagon. The problem is not as simple as the solutions above. Mine are adjusted to park as low as possible when off. Even so, the blade on the drivers side goes all the way off the windshield. The Subaru dealer wants to replace the whole wiper blade transmission for about $450. Looking online it seems to be interconnecting arms and pivot points that connect the motor to the wiper blade arms.

Open the cap at the end of the windshield wiper arm at the cowl of the Blazer.This will reveal the bolt that secures the wiper arm to the wiper linkage.unbolt the wiper arm using a 3/8-inch ratchet and socket. Place the bolt to the side, as you will reuse it later. Pull the wiper arm up at the blade so that the blade of the wiper is pointing into the air. Then pull at the base of the arm, wiggling it slightly. It's a keyed gear, so it may take a little bit of work to break it free, but with the right amount of wiggling, it will disengage. goodluck

Hi,
Open the cap at the end of the windshield wiper arm at the cowl of the Blazer. This will reveal the bolt that secures the wiper arm to the wiper linkage. Unbolt the wiper arm using a 3/8-inch ratchet and socket. Place the bolt to the side, as you will reuse it later. Pull the wiper arm up at the blade so that the blade of the wiper is pointing into the air. Then pull at the base of the arm, wiggling it slightly. It's a keyed gear, so it may take a little bit of work to break it free, but with the right amount of wiggling, it will disengage. Then you can replace the new windsheild wiper arms to it.

Thank you !!

Try a new set of blades. Sometimes the cheaper ones dont flex properly

try loosening negative battery clamp,w/ key on acc.& wipers on,remove cable when wipers are up.

How to Replace Wiper Blades Guide (Typical):
Potential tools needed to replace wiper blades:

• Flat blade screwdriver (small)
• Small nosed pliers
• Latex or vinyl gloves
• Safety goggles

To replace wiper blades theactual action of replacing the blade is no big deal, it's the locationof the blade down below the hood that can make it difficult though.Sometimes it helps to open the hood to gain access to the wiper blades.Other times it is helpful if the wiper blade is somewhere in the motionline of wiper action. The trick is to get the wiper to stop somewherein the wiper arc. Turn the wipers to the on position and allow thewipers to start, and then shut the key off when the wiper has arrivedin a desirable position on the windshield. To replace your wiper bladesplease follow the step by step instruction below. Also, watch the How to replace wiper blades video below to gain additional information. The method in which the wiper blades are attached will vary slightly.

• Step 1: With the hood closed, turn the wiperson, when the wipers are in the middle of their arc turn the key to theoff position. (Note: if this can't be done because of wiper conditionand you want to avoid scratching the windshield please open your hoodto gain access)
• Step 2: Locate the mounting clips at the top pivot on the wiper blade
• Step 3: Release the clip and remove the wiper arm
• Step 4: Match the size of the old blade against the new blade to ensure proper fit and operation
• Step 5: Reinstall the new wiper blade and recheck wiper operation

Common Problems:

• Make sure the wiper blades are the same size as the original blades.
• When replacing wiper blades not getting the blade onthe mounting pin completely allowing the wiper arm to become dislodgedand possibly causing damage to the windshield.
• Using wiper blades after the blade has failed permanently damaging the windshield by craving scratches in the wiper arc.
• Wiper blade can create a chattering noise when theblade is not properly balanced allowing the blade to "flop" back andforth as the wiper direction changes.

I hope help you with this (remember rated this help) Good luck.
