You didn't say what kind of car this is but there's a metal actuator on the end of the switch that broke. You need to disassemble the steering column, this operation requires special tools starting with a steering wheel puller after that there may be a lock plate if not remove the turn switch to access the pin you push to release the switch.

Did you try replacing the headlamp bulbs ?
Low Beam Headlamp Operation
The low beam headlamps may be turned ON in 3 different ways:
• When the headlamp switch in the HEAD position for normal operations
• When the headlamp switch is in the AUTO position, for automatic lamp control (ALC)
• When the headlamp switch is placed in the AUTO position, with the windshield wipers ON in daylight conditions, after a 6 second delay
When the headlamp switch is placed in the HEAD position, ground from G304 is applied through headlamps ON switch signal circuit to the body control module (BCM), signaling the headlamps ON request. In response to this signal, the BCM applies ground through the headlamp low beam relay control circuit energizing the LO BEAM PCB Relay. With the relay energized, battery voltage is applied through the switch side of the relay, the left and right low beam fuses, and the low beam supply voltage circuits illuminating the low beam headlamps. Ground for both headlamps is provided at G104.


Do you know how to test automotive electrical circuit's using a DVOM - digital volt ohmmeter ? Also ,do you know what a PCB relay is ? PCB - printed circuit board relay , which means it's soldered onto the circuit board inside the under hood fuse box . Using a wiring diagram check input from headlamp switch to the BCM ( you could do this with a scan tool if you had a professional type ) And check for control of PCB relay . at connector 2 pin 10 underside of under hood fuse box . You would need print out of connectors for under hood fuse box to determine which one you need to check . Your best bet mite be to have a qualified repair shop check it out .

This can occur if there is a blockage in the heater rad, or the blend door actuator that regulates air temperature into the cabin is malfunctioning, or the cooling system thermostat is malfunctioning. You can check by carefully feeling both heater hoses under the hood after the car has been run for a while - if one is hot and the other is cold, it's a blockage. If both are cold, check the thermostat. If both are relatively hot, it's usually the actuator.

May physically fit but different fitting placement. Two different part numbers are listed for those vehicles

Check your battery cables Buicks were noted to have two positive cables. One primarily for the starter and the other for systems.

No turn signals, then check the fuses in the fuse box. Check your owners manual for the location and fuse size. As to get the radio code, take it to your auto shop and they can call the dealership and get it for you. If they will not do that favor, you need to find another shop to do business with.

The 800 number and process on YouTube no longer work. Unfortunately, it must be done by a dealer. Also, be sure that the part number on the new radio is the same as the old radio. Many look the same but have different part numbers and are specific to a particular GM vehicle and frequently different year.

Jennifer on most all older GM vehicles lift the hood and the relay boxes are on top the inner fender well ( or real close by) on the drivers side. A black box with a lid. Unhook the lid and if not on the outside once you take the lid off turn it over and there should be a diagram showing which relay is which. If you can't find it look behind the grill and unplug the actual horn or horns until you do. Smack the horn button hard a time or two also. The horn button could be stuck in the on position. Hope this helps you.

Those are transmission codes, you may hav ed as bad TCM. (Transmission Control Module) I would take it to a transmission shop and they can tell you exactly what they mean.

Did you check to make sure your fans are coming on? I believe you have two, the one on the drivers side is the radiator fan while the one on the passenger side is only for A/C. Do you have a bleeder valve on the thermostat housing? If it does you need to bleed the air out. Easily done, let it idle, open valve and leave it open until a steady stream of antifreeze comes out.
I really think you'll find your fans not coming on. Hope this helps you.

Could be a lot of things, depending on whether the car is moving or not. For example, it could be a relay chattering. Figuring this out will need you to look behind the dash to locate it (take off the knee bolsters underneath the dash on the side the noise seems to be coming from).
