okay guys so i just bought this 40th anniv. ruby and now the blower wont shut off for the ac. i had it running the other day and then once i shut the car off the blower stayed on. i had it on the face setting and after taking the key out of the ignition it switched to floor and defrost setting. also i cannot adjust the speed of the blower when it is running. i have to unplug the motor under the hood to keep from killing my battery. any help would be appreciated!!
