How do you replace the turn signal switch located on a 1995 Chevy Lumina?
This is a nightmare, only try it if you are a very qualified auto mechanic.The Signal/High Beam Cluster housing-body plastic is usually defective/inferior and will stretch causing the points to arc, casuing heat and smoke/fire, needing replacement. I replaced mine successfully. Disconect the battery(big job on A Lemona). Remove the horn pad. Get a steering wheel puller and remove the wheel. Disassemble the steering column covers (carefull unscrew and pull apart the snap-together parts), and lower dash. remember how it goes back together and keep all parts or your self-cancelling signals feature wont work. The Switch is not a simple local wiring bus/plug and play affair. Its wiring loom leads down to the Main Harness Bus Connector which connects all the local bussworks to one connector. This main conncector is "self disconnecting" when the center bolt is loosened (but still needs a little pull apart). All the sub- busses' connectors must be sistered together paralell on re-assembly. The hard part is re-conncecting all the connectors simultaneously to the main connector(like 60+ delicate connector pins, one bends- and it will short out the whole harness)(more smoke and fire). It is supposed to be self-centering when the center bolt is re-fastened, but you have to be really carefull keeping things lined up straight. Also, If I remember Allen wrenches are needed as well as torx tools, and some are tamper-proof torx that require the center nub deleted with a small punch. I Advise you take it to a qualified mechanic, let them assume the risks, I WOULD NOT DO IT AGAIN MYSELF. Or move to Florida, no one there uses signals anyway.
