Why does my 2001 silverado overheats only when i turn on the A/C ?
The only way that could be possible is if a/c is some how switching the fan off at the radiator/condenser, so first question is with the engine running and a/c off see if the cooling fan kicks in, if it does and at the exact same time when it does, switch the a/c on and see if the fans turn off! The fans should be on or switching on and off when air con is on, hope this puts you in the right direction

Will not start will only turn over
Check that your spark plugs wires are properly connected.
Check your spark plugs and see if they look good.
Check your gas input and gas filter. Take your gas hose off at the fuel injection port and see if gas is coming out of the hose.
If not, it could be your gas filter.

02 SILVERADO. AIR ONLY BLOWS OUT DEFROST VENTS.
I had a similar issue on an 05 silverado. Air would only blow out of defrost vents. But this worked for me:
1) Unplug HVAC fuse for 10-30 seconds
2) Start truck
3) A/C comes out defrost - wait about 10 to 15 secs
4) A/C then starts coming out the floor vents for about 5 seconds
5) A/C then starts coming out the dash vents.
6) While the A/C is coming out the dash vents, turn A/C OFF (otherwise it cycles back to defrost for good).
7) Turn truck OFF
8) Restart truck and it should work fine

Replacing ignition switch in 2001 chevy silverado
Not the igniton switch, its the ingition cylinder and or the housing. The switch is not part of what you are really turning. It's connected to it via gears. The common problem is the key gets worn out and the tumblers wear also. Eventualy they do not line up right and will not make the "bar" drop in the cylinder to allow it to turn from the off positon. If you have the title in your name and the key has never been rekeyed or the code has been changed you can go down to a dealership with all of the info for the truck and they can cut you a key from the vin number. You can try that first before you put a cylinder and housing in it.

Brake pedal is intermittent spongey on my 2005 silver ado Z71
One of two issues are typical. Either a bad wheel cylinder(s), or a bad Master Cylinder. The sponginess is caused by air or some other contaminant in the hydraulic fluid. It's intermittent because the more often you use the brakes, the hydraulic pressure is built up. If you pump the brakes before stopping, the sponginess will be less. Check all brake cylinders, and Master Cylinder, and possibly a complete Brake system fluid flush.
