How to rpl 98 GMC K1500 PU ignition lock

You'll need to pull the steering wheel. Might want to do a search for a youtube video. 1988 to 2000 models are similar I think.

My 98 gmc 1500 V8 5.0l won't start. Has good spark

Spray starting fluid into the air intake of the engine, if it starts and you have fuel pressure you have no injection or injector pulse as we call it. Check ECM fuse one and two for continuity if it starts with fluid..

The heater / ac in my 2006 GMC Sierra 2500HD has gone out several times. It has always been corrected by replacing the resistor. Replacing the resistor did not work this time. I have checked the fuses...

You have replaced the resistor and the blowwer is good and the fuses are good then i would say its in the switch or power to the switch, maybe at the ignition switch there a bad wire . sometimes the power wire going from ignition switch heats up and causes a bad connection, if you pull connector off the switch make sure the connector to ignition switch is not melted or burnt and also check blower control for the same, i would say that your blower is bad and drawing to much current if you have replaced a few resistors, i think maybe theres a fuse under the hood in the fuse /relay box that may be out or the connection at the switch or ignition is melted. hope this helps.

2004 gmc sierra acts like the key is in the ignition when its not, the warning bell goes off+the doors wont lock ,like the key is in the ignition

sounds like either key in cylinder contacts are bad or the 2 wires going up column to the switch are pinched together.

How to remove an ignition on a 1997 gmc sierra but without a key

The lock pin that's keeping you from removing the switch normally won't push up but some do, try that first. Next is to drill out the core of the lock cylinder without going past the edges of what's being replaced. You'll need some needle nose pliers to pull out the internal parts once you drill a large enough hole & you'll be able to turn the cylinder to where the pin will release & let you extract the remaing part.

good luck

Air bag light won't go off

It likely is a bad passenger air bag. Did you try switching it back to off on the switch,and unhooking the battery for 5 minutes.

98 Sierra 3/4ton 4x4 turbo wont start

When you turn the key to on, the dashlights have to come on and go off when you turn it to the starting position. Make sure you have a good battery first. No dash lights indicate a bad ignition switch. Check all fuses and relays. But I am pretty sure it is the ignition switch.
