Column shifter not working

Under the shifter you'll see a small plastic plug. pop it off and insert a screwdriver and push up on the switch. This will release the shifter. Check to see if you have brake lights, if you do that switch needs replaced. If not replace the brake switch.

I have a 1998 gmc yukon and i need to replace the brake booster but i dont know how what do i do?

Can you provide me with additional information? Such as, does the brake pedal go to the floor when applying the brakes, are the brakes spongy, non responsive? Is there anything leading up to this issue, such as a minor accident?

1999 GMC Yukon, Do I need to replace the stop light switch if my brake lights only come on when I push the pedal real hard to the floor. I have already replaced the brakes and did a new brake booster. Is...

Sounds like you are on the right road with the switch. Before I bought a new switch I would locate the switch, it will come in direct contact with the brake pedal arm, and see if there is an adjustment or if it has moved for some odd reason. Sometimes things just happen.

How do I replace the brake light switch in a 1999 GMC Yukon?

Hi there,

Well go to the brake pedal and it is mounted under there then unplug the connector and screw out the part then screw the new one in and replug the connector in.
The switch is usually made of plastic and has a 2 or 4 wire connection and what looks like a threaded rod with a button on the end.
The switch is removed by pushing the button end of the switch with enough pressure as to cause the threaded portion of the switch to push out of the metal collar that supports it. 
Installation is just to push the threaded end of the switch back into the metal bracket until the button touches the brake pedal arm. Post further comments for more help or information.......

Good Luck!!

Brake lights for 2005 gmc yukon does not work.

If your fuses and bulbs are all good, then look above your brake pedal and you will see your brake switch up along your brake pedal arm. It will either be between the brake arm and the firewall so when you brake it pushes the switch in. Or it will be between the dash and the brake arm so when you brake it pulls the switch out. Most likely this switch needs to be replaced

While in stop and go traffic my brake pedal went

check the brake fluid level, if its low, there may be a leak, if the level is good, the master cylinder is bad.

Brake lights stay on till the pedal is pulled back not the switch I replaced it

Two things come to mind:

1) Pivot bushing on the pedal swing arm might be bad.

2) It could be the brake master cylinder is sticking/binding and not allowing it to return all the way. The MC connecting rod may need adjusting, too.

Brake Light Switch clip on 94 GMC Pickup

My 1996 Brake light clip needed to spread open with a screw driver(some what like a round spring) and with another screw driver push the switch up the pin. The switch will push the clip off the Pin. The pin has a head that needs to clear clip while the spring clip is spread open. It took me a while to figure out.
