What is the cost of replacement of a turn signal switch in a 2001 Chevrolet Lumina?

Question edited for a lot more clarity.
Question moved to model category.

It might be the flasher relay and it might be the horn relay although horns tend to seize up through lack of use. the flasher relay is is separate to the Hazards relay which is often part of the switch.

stop light not work turn went out at same time

Check the turn signal switch. especially if the center brake is the only brake light that comes on when you step on the brake pedal. Sometimes wiggling the switch will get the brake lights to work momentarily.

could be the signal switch, signal goes from the brake switch to the signal lever then to the brake lights

YEP TO FIX BRAKE LIGHTS YOU HAVE TO REPLACE TURN SIGNAL SWITCH BECAUSE MY 98 LUMINA DID THE SAME THING.YOUR BRAKE LIGHT SWITCH AND TURN SIGNAL SWITCH SHARE THE SAME ELECTRICAL CIRCUIT.

Yes your going to get stopped. Do you think they'll look the other way. I've this be as simple as the connection at the bulb is bad and bent some metal to make the conntact.
Not sure what under the steering wheel has to do with brake lights????

yes,you will need to replace the multi function switch,

It is the turn signal switch all together. I have owned that same care for about 5 years now and every two years it goes bad. It is just a glitch in them. Cost is around 80 for the part plus labor.

test and replace the brake light switch, it is located at the top of the arm the brake pedal is attached to.

does it have a coded key?
