HOW DO YOU ADJUST THE WIPER ARM TENSION HAD WINDSHEILD REPLACE AND NO WIPER IS BLOWING AROUND NOT CLEANING OF WINDSHEILD WHEN DRIVING OVER 45 MPH EVERYTIME A TRUCK GOES BY THE WIPER FLOPS

Where is the blade when switch is off? Some of the GM cars in the 2000 years had problems with the post where the wiper arm attaches. The post will strip the groves when trying to move heavy snow. You will have to remove the arm, and reinstall it when the wiper switch is off.

pull the arms off the shafts and cycle the wiper motor to the stop position . Replace the arms and tension the nuts.

your best bet would be to put shorter wiper blades on car, if the arms are not out of adjustment. you can tell if the arms need readjusting. by watching and make sure they go all the way down and stop ok without hitting trim on windsheild bottom. hope this helps ! good-day !

remove black plastic cap at base of wiper arm,tighten 14mm nut underneath cap while wipers are off and arm is in normally parked position ,replace balck plastic cap and you should be good to go!you might want to snug up the nut on the other one too!

first remove wiper arm again and ignition on then switch on wiper without arm, let it run few second and switch off wiper wait few second and switch off ignition, now it has come to the rest position so you have to install wiper arm at rest position. don't let it to move when you tight it hold it by hand, I think this information be help you if you think right way what i mean. is this information helped you?

Try this:

With ignition on, turn on wiper switch. When wiper arm gets to point where blade does not touch screen, turn off ignition switch so that wipers do not return to park position. It may take a few goes to stop arm in the right position so repeat process until it is in the best position.

Check main wiper arm and bend slightly towards windscreen so that blade touches screen and there is some spring pressure from the arm to keep blade on screen. Also check that there is no interference between main arm and the section which supports the rubber blade. If you get blade chatter as the arm sweeps, twist the end of the main arm slightly in the opposite direction to the movement that produces the chatter. It may take a bit of trial and error to get it all right.

Lift up wiper arm
Release small tab on side of wiper, where it goes over the drive post
There is a tool for hooking onto the wiper arm,to hold off spring tension,and makes it easier to position,when replacing

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 !!

there is no tension adjustment if the arm is too loose and dosen't put enough pressure on the windshield you need to replace the arm you can bend the center of the arm very slightly and get a little more tension BUT the arms are over 15 years old and teh springs are probably weak
