Heater fan motor will not cut off after turning car off?

Where is the ground on a 1993 Lincoln Town Car if causing lights to dim and blow headlights and blower motor control on heater to cut in and out?
the heater box is located on the passenger side of the car under the hood. To access the blower motor it may benecessary to cut the outline of the blower motor from the housing, there is a "cut here to service" printed on the outline. also you have to remove the control module and the radiator reservoir for working room. I recommend leaving the wires to the control module hooked up. allow one good hour…
The heater blower/motor seems to be incased in a plastic housing on the passenger side firewall , right behind the on-board computer. There are 3 screws holding the computer in place and need to be removed, to access the heater/blower motor behind it. The plastic casing needs to be cut with a utility knife to access the blower itself.
