How do I change the blower motor in my car so i can have some heat it is a 1990 chevy corsica

annette, get a month of alldatadiy.com and get step by step instructions - or if you have a manual to use thats great.

it's under passanger side of dash. remove a few screws from the under side panle and remove it. next the motor will look like a cylinder hangging down. it is part of a dish like plate. remove the screws holding the plate to the heater housing. the motor will start falling out with the removel of the last screw. lower it down disconnect the electrical connector. reverse to install. good luck and let us know how you make out.
