Remove and replace wiper blade assebly 89 chevy silverado

Replace the wiper motor assembly. I would guess that you have destroyed the logic in the control assembly. Electronics do not like being reversed on polarity.

Possible wiper linkage has broken/seperated from wiper motor. The wiper cowling covering the linkage assembly will need to be removed to inspect/repair

there should be plasic clips in the pakage the wipers came in one of the clips will fit aqnd the other wont when you find the right one snap it into the new blade and clip it on to your wiper arm. if you dont have the right blades the correct clip may not be in the pakage.

Lift it up and pull the retainer ring off, then pull the whole assebly off. They sell the whole assembly as a replacement, not just the blade.

Hello, my name is Ben and I can help you with this problem. This is a very common problem with Chevy. You need what is known in most vehicles as a "pulse board". The pulse board is located inside the wiper motor control module. On many vehicles the pulse board is replaceable, unfortunately on your Silverado you must replace the entire Wiper Motor Control Module which is bolted onto the top of the wiper motor. To get to the wiper motor, first remove those little nut covers on the big end of the windshield wiper arms, if you slip a small screwdriver or your fingernail they just pop off. Now unbolt the windsheild wiper arms, before removing the wiper arms, mark their location on the windsheild with a grease pencil or magic marker. The arms are hard to remove, you need to kinda wiggle and pull at the same time, now that long plastic cowl needs to come off, those clips at the front edge just slide forward, then at each end lift up that rubber flap and remove those TORX screws. Remove the cowl and set it somewhere SAFE, it's easy to break. You will now see the control module mounted on the wiper motor, unplug the electrical connections and remove the TORX screws holding it to the motor. Assembly is the reverse of dis-assembly. If you have any trouble or questions, feel free to ask, Ben.

Sounds as though you have a short lift hood and and giggle wires going to wiper mot-er while wiper switch is on if it starts that means you have a short. If not replace wiper motor.

With the pin style blades, if you look into the top of the blade at the point were the pin goes through, you will see what looks like a spring or a coil on its side. Use a small screwdriver and push down on that coil at the same time that you try to push the wiper off the pin. I have changed more of these than you can think of, and they are never easy, you have to get things in just the right possition before it will come all the way off. Once you do one the other will come off easier. One word of caution,don't let the wiper arm slip out of your hand and smack the windsheild, it can break it.

i believe that this wiper is actually a hook type where you remove the whole blade assebly by pushing in the sides at the connection where the blade meets and then pulling down the whole wiper blade from the rod it connects to(in other words if you pull the wiper blade upright and away from the window you actually pull the whole blade assembly doown towArds the hood)

The plastic bracket that holds it in has either a 10mm or 8mm holding onto underneath but if you need to replace bulb you dont have to remove the entire assembly

I replaced mines not too long ago. I have a BMW 3281 -1999. I am not sure if the 2000 is much different. But hwat I did is as follows.

1. Remove the plastic covers.
2. Remove the nuts holding the wipers
3. To remove the assebly DO NOT pull straight up, but rather start pushing the wiper down against the spring loaded mechanism. Do it several times and you see that the assembly starts coming off. (this is the trick a learned, otherwise is it almost imposible to remove them).
4. Once replaced, put back together the assembly, nut and plactic cover. The whole job should take you like one hour.
