How do I change the washer pump on my Toyota Corolla?

I have a 91 Toyota Corolla - 4 dr sedan. I have checked the nozzle for the windshield sprayer and they are not plugged but the water only sprays about 4 inches out of the nozzle. I am guessing that the washer pump needs to be changed. Any other ideas what the problem could be? Thank you.

double check the lines by spraying some compressed air through the lines....shop air lines will blow off a fitting but it will also clean out the lines....if it is the motor it is just a small grommit in the bottom of the tank and then a clip for the electrical connection....no worries won't cost more than 15 bux or hit a junk yard
