I cannot speak for all models, but my 1989 Buick Century has a drainage valve located near the bottom of the radiator on the driver side of the car, and can sometimes require pliers to open. It's usually easiest to look for it from under the car....Thanks

The radio in my 1996 Buick century had a clock light that did not go off when the car was shut off, so the battery would go dead after 2 days. Disconnected the radio and all was well. Getting ready for a new radio now.

There is a bulletin for this fix.The bulletin number is 05-01-39-001A.This pertains to the blower motor staying on after key is shut off.What you will have to do is replace the blower motor resistor module and install a capacitor in the wiring.Part number is 25073556 for the capacitor.The blower motor is on the right side under the dash.Just remove the insulator panel and you should be able to see it if you look up into the dash.Or turn it on and listen for the blower motor.Disconnect the connector to the blower motor control module.Find cavity a and c.Cavity a is negative and cavity c is positive.C is red and A is black.Splice the positive lead of the capacitor to the red wire and the negative to the black wire.You should use splice sleeves and solder the wire on.Hope this helps.Good luck.
