These are actually the bulbs that have went bad. It would be quite expensive. I have a 2004 that has done the same thing. No lights behind any buttons any more except the ac heater controls I replaced last year.

Could be a bad cable. If it is broken into, you'll get swings like this. If you are handy, you can replace it yourself. If not, most garages can do it for you.

take the wiper arm off, look at the spline for the arm and the car and see if either is stripped

1234 down the right side 5678 down the left. this is veiwed from the rear of the engine as if you were sitting on the transmission.

Changing front, right turn signal on 2005 Buick Terraza: Open hood; when facing the front of vehicle, the right turn signal is on the passenger side (left). The headlight assembly needs to be removed to easily reach the turn signal. On my vehicle, there is a 10 mm screw on the left side. Remove it. There is L-shaped pin on the right side of the headlight assembly. Swing the pin counter-clockwise (to the left). Pull the pin straight up to remove. The headlight assembly is now loose, but there is a pin snapped in a socket on the back of the assembly that still holds the assembly. Pull the headlight assembly hard and straight to the front of the vehicle. When it snaps loose, the assembly is now held just by the rubber gasket surrounding the assembly. You need to gently work the right side of the gasket out of the grill cowling. The assembly should pull straight out. The wires are long enough to lay the headlight assembly in the engine compartment. Finally, the turn signal is now accessible. Twist the light holder counter-clockwise and pull out the light holder. Change the bulb. Do not punch your man-card for credit until you have successfully reinstalled the headlight assembly. It goes back in a little easier the second time. Once you have put the L-pin in place, the screw back, and successfully tested the lights, you can now punch your man-card.

I give the mechanical engineers and designers a D-minus instead of an F only because I was successful on the first try. No light bulb on anything commonly used by people should be this hard to figure out.

If I'm not mistaken they run across the engine cradle from left to right and down the passenger side.

If this is the 3 button HomeLink Transmitter usually centered overhead above the rear-view mirror, this should work:

While the engine is turned off follow these steps to program up to three channels:
1. Decide which one of the 3 channels (one of the 3 HomeLink buttons) you want to program.
2. Press & hold the desired button through step 3.
3. When the HomeLink indicator light begins to blink slowly(this may take up to 30 seconds), hold your hand-held garage door remote about 1 to 3 inches away from the buttons & then press and hold the button on your garage door remote. Continue to hold both buttons until the indicator light on the HomeLink begins to flash rapidly(this may take up to 90 seconds).

If it still doesn't work, make sure the batteries in your garage remote are not weak, and try again moving the remote back & forth and left & right or turning it upside down while programming.

Also note HomeLink will not work with older garage door openers, especially not with ones manufactured before April 1st 1982.

If your tt is equipped w/ power mirrors the switch is on the driver door panel behind the master window switch.  Just twist knob either left or right.  then move knob up or down, or side to side.  Do this with the vehicle on or running.  If switch is in middle it will not do anything.
