You have to remove the wiper arms then the cowling. Remove the retaining nut that holds the arms to the back of the wiper motor. Disconnect the wire connector then remove the 3 bolts that hold the wiper motor to the fire wall. Reverse order to install new motor.

My wipers work when they want to don't always work when it's raining. Is there a recall on the windshield wiper motor for a 1997 Chevy Blazer?

I don't believe there is a recall but I've replaced a lot of the wiper control modules [glorified circuit board] on top of the wiper motor for similar problems. Something in the circuit board goes bad and causes the wipers to malfunction randomly. There are other things that can cause wipers not to work but I'd look there first

Wipers work intermittent

Hello bdsisselI.
I suspect the circuit board on your Pickup is at fault here. Very common problem with the solder joints cracking.
Two ways to repair it. If you are handy and if you or someone you know can use a solder gun you can often save the board. Otherwise buy a new one at your local auto supply.
On your wiper motor, just above where you put in brake fluid, on the firewall, there are 3 screws with torx head screws. Unplug the wire connector. Remove the screws and pull off the cover. You will see the back side of the circuit board. Gently pry the board out (it is retained by metal friction clips).
Inspect carefully the circuit board on the end where the plug is and you will find the cracked solder. Hit them with the solder iron and viola, no more problem.
Hope I helped you along with this.

I have replaced wiper motor 4 times last three years, wipers come on by them self run minute or 2 shut off, and it seems to start after I use touchless car wash. After I replace motor wipers work fine for...

This is really an easy fix. The wiper motor assembly is on the firewall, just right of center. The wiring can be unplugged before the circuit board is removed, or afterward. I found it easier to unplug it after the circuit board was removed. There is a flat cover that is held on with three torx screws (T20). Remove those screws and remove the cover.
The circuit board will now be visible. Remove the circuit board by grasping the wiring connecter and gently pulling it towards the front of the vehicle. When the circuit board has fallen free, unplug it from the wiring harness if you haven't already done so.
The solder joints that connect the wiring socket to the board go bad on the board.  Just resoldered those and re-installed the circuit board. 

Good luck and hope this helps. keep me posted, be glad to help.

Need wiring diagram

i dont think u need a wiring diagram. you should check your wiper motor circuit board first. on my 94 s10 the wipers either worked when they wanted to and now they dont work at all. just either replace the circuit board yourself ($19.95 on ebay) or replace the whole wiper motor ($60 on ebay) and your wipers should work. just give this a shot as its a good place to start. i myself am going to replace the wiper circuit board as its cheap, and really easy to access and replace. all you need is a screw driver. good luck. and no, im not a GM Technician. just owned my truck since day 1 and always try to check vehicle forums for answers first.
