I have a 2003 Yukon Denali. I believe that the ignition switch is bad. How hard is it to change the switch

I have the exact some problem 01 Yukon 5.3 – Sometimes my security light also comes on for no reason? Wonder if this has something to do with the remote starter? When this does happen all I have to do is wait for 15 minutes and it fires up just fine. Pisses me off though…

make sure the wheels are straight.. if you park them with them turned to one side the steering column is under a bind.... if they are turned all the way to the right you will for example have to turn it a little to the left to release pressure as you turn the key...

SOURCE: 03 Yukon denali park brake warning wont turn off

hi for info the brakes warning light on dash is also an indication that brake fluid level is low? or there may be a leak resulting in fluid level drop ? also considering age of car you may need to inspect brake pads wear ? if your car has low brake pads wear indicators attached to pads ? or the hand brake switch req's checking to ensure it is being pushed to off position when h/brak is down ? so fluid level low is the obviouse 1st check as fluid will displace from reservoir as pads wear low hence the level indicator on fill cap trips on may i suggest if it is low level b4 you top up? check your b/pads if you have not done so recently? or replaced since new ? hope this helps you locate problem best wishes from the uk

Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.
