You may be able to get a direct replacement at the auto parts store, but actually separating the pieces of the exhaust is quite a chore, as they tend to bond together with corrosion/rust. Cutting and welding is often necessary. Taking it to a reputable shop may be a good idea.
The starter is located under the motor on the drivers side...if you're looking at it from under the car (which is where you'll need to be) it will be to the right and back of the catalytic converter. There are two silver pipes that run right by it...
If your check engine light is blinking that means an engine cylinder misfire has been detected . You can drive it in for repair , just avoid any rapid aceleration or deceleration because you can damage the catalytic converter
I have a 1999 blazer. The heater core clogs up about once a year from the Dexcool. Try having it (heater core) flushed and use Prestone (Extended life) instead of Texaco.

No, not if it is not defective. If the ignition switch is defective then that is all you need to replace.
How much does it cost to replace the catalytic converter on a 1999 Toyota Tacoma
Replace it
It is possible to replace the catalytic converter with a straight-through section of exhaust pipe, but understand that doing so puts you in violation of pollution laws in most states and definitely Federal pollution laws.
A shop can cut the bad converter out and weld a new one in.
Replace
In exhaust pipe before catalytic converter unscrew to replace
best if you take it to a shop unless you have a welder.
there are 3 O2 sensors on the 4.3 Vortec V6 Blazer ( I have a 99 as well) 1 is on each exhaust downpipe forward of the catalytic converter, the 3rd is just aft of the converter.
The oxygen sensor on a 1999 Honda Civic is located on top of the catalytic converter. The catalytic converter is under the car.
