Question about Chevrolet Chevy

Fried wire to my ignition switch

My '56 chevy has (I think) the original ignition switch, and the key cylinder is very "loose and sloppy." While movin' on down the highway smoke started billowing from the under the dash. I shut everything down and disconnected the battery. After towing it home, I found that the main wire from the battery to the BAT terminal on the switch was fried to a crisp. The wire looked to be about 14 gauge. Should this wire have had a fuse (it didn't). The insulation on the wire had melted and fused itself to the adjacent wire coming out of the switch, but I don't know if this was the cause or the result. I cannot locate the source of this problem. Did the ignition switch just give up the ghost? Would a worn key cylinder have anything to do with it? Obviously I don't want this to repeat so I need to find the cause. Thanks for your help.

Most likely the wires rubbed together or wire grounded out. You could put an inline fuse in wire for safe precaution Replace switch and run new wire and should be good to go.

Bi pass passlock 1 on a 97 chevy cavalier z24 manual clutch security light stays on after 25+ min do not have original key .

Replacing the lock cylinder won't do solve your Passlock problem. It's the lock cylinder CASE that's the problem most often. First, do you have the right transponder key? If so, then get the trouble codes read to find out whether the problem is the tranceiver or the lock cylinder case. Then replace the broken parts and get it reprogrammed. This isn't rocket science. But you do have to know how the system works.

I am wondering why when the key and probably the cylinder is worn you changed the ignition switch?

Your car is young enough to have an immobiliser as standard, probably a passive type with a coded transponder in the key. Perhaps it is that causing the trouble.

Coincidence is possible so verify the starter is still functioning by energising the solenoid at the starter if it is accessible. If the engine cranks and starts all is well. If it cranks and doesn't start then the immobiliser is a possible cause. If it doesn't crank the starter could be faulty.

If it cranks and starts I advise going back to the ignition switch and energising the starter from there by bridging a live wire to the starter wire. If it doesn't crank it is either a wiring fault or the immobliser if it has one. If it does crank and start the fault is likely wear in the part of the steering lock that drives the ignition switch.

Good luck!

As long as the ignition key cylinder has never been changed, dealers will have records of factory key cuts going back some years. I think the cut off is 10 years but I could be wrong.

Something to do with the PASSLOCK system - anti-theft . Loose passlock sensor or key . Thing's do wear out after time . The passlock sensor is part of the ignition lock cylinder housing .There is also a magnet in the lock cylinder an when you turn the key the magnet rotates past the sensor causing a voltage signal that the module in charge (BCM) reads ,worn or sloppy fitting parts are probably the problem . Your vehicle is 14 years old , just think of how many times the key was stuck into the ignition switch an turned . Don't know of any by-pass fixes for this , look on line . Or you probably would have to replace the whole lock an lock cylinder .

Ignition lock cylinder keeps blowing

I don't think the key and tumbler is your problem at all. The switch is down on your steering column. It's either loose and sliding around when the rod pulls, or it's wrecked. They can cause all kinds of problems. Just drop your steering column and take a look.

Ignition key switch

You have to use a pin or paper lip to insert in hole in igmition switch to release the lock cylinder. The key has to be in "on" position I think.

  1. Disconnect battery ground cable (14301) .
  1. Turn lock cylinder key to RUN position.
  1. Place a 3.17mm (1/8-inch) diameter wire pin or small drift punch in hole in upper steering column shroud (3530) under ignition switch . Press retaining pin while pulling out on ignition switch to remove it from lock cylinder housing (22074) .
  1. Install ignition switch by turning it to RUN position and pressing retaining pin. Insert ignition switch into lock cylinder housing . Ensure ignition switch is fully seated and aligned in interlocking washer before turning key to OFF position. This will permit cylinder retaining pin to extend into lock cylinder housing hole.
  1. Rotate ignition switch, using lock cylinder key, to ensure correct mechanical operation in all positions.
  1. Connect battery ground cable.
