purge solenoid is on the intake on the passenger side with a plastic line going to it
SOURCE: purge solenoid location
which vehicle are you actually looking for the purge solenoid on? you have 2 vehicles listed in your question. i'll answer both, lol
the locations are described as if you are looking at the engine from the front of the car with hood open.
on the blazer:
it is located on the left side of the intake manifold just under and behind the throttlebody. it is a canister looking device.
on the silverado:
it is located on the intake manifold on the left side in about the same spot as the blazer. providing the silverado has the 5.3 or 5.7 liter engine. if it also has the 4.3 then obviously it will be the same.
hope this helps!
SOURCE: where is the purge valve located on a 2004 honda LX?
It is with a 2 wire Black connect located next to the throttle body. Locate the green cap on the evap hose and follow it to the throttle body and that is the purge valve.

PCV . Positive Crankcase Ventalation Valves are always located in the valve cover pans with a hose attached usually leading to the air cleaner, or some other vacuum source..

There is a purge solenoid for the EVAP system and it is item no.# 1 shown in the diagram below. You have to follow the purge valve vacumn hose to find the charcoal cannister if you need to inspect.
I have included a description of the EVAP system for your understanding.
EVAPORATIVE EMISSION (EVAP) CONTROL SYSTEM
The EVAP and on-board refueling vapor recovery (ORVR) system consists of a fill vent valve, fuel shut-off valve, fuel cut (roll-over) valve, fuel liquid/vapor separator, EVAP canister, EVAP canister purge solenoid valve, EVAP canister close valve, vacuum relief filler cap, and connecting lines and hoses. ORVR system is designed to prevent the release of fuel vapors during refueling. During refueling, as fuel enters the fuel tank, a vacuum is created in filler pipe, drawing air into the filler pipe and tank. Fuel vapor in fuel tank is then forced to the EVAP canister via the fill vent valve and the fuel liquid/vapor separator. A fuel tank pressure sensor is used for detecting EVAP system leaks by comparing pressures inside and outside of fuel tank.
EVAP Canister Purge Solenoid Valve
Fuel vapors are vented into the EVAP canister during refueling and when ignition is off. When engine is at normal operating temperature and engine speed is greater than idle, a thermovalve opens and allows vacuum to open the purge control valve. Canister vapors are then drawn into the intake manifold for burning during combustion. The purge control valve is kept closed during idle and engine warm-up to reduce HC and CO emissions.
