I am having the same thing. I talked to a guy tonight said take the fuse block under the hood, and flip it. Look at the right side section, bottom left corner a thin red wire was burnt up inside the connectors. His friend works for the dealership told him where to look. Said so many of thesetrucks have this issue but Chevrolet wont do the recall. He also said check them all just in case. It wont cost you anything but a little bit of time. I'mchecking mine tomorrow. I had my transfer case rebuilt, new pushbuttons, new tccm, new transfer case motor, and still nothing. My next step was a auto electrical shop. I truly hope this helps because I know your pain. And stress.....oh the stress

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: 01 Chevy Silverado 4 X 4 not working. 4WD light

Having the same exact problem but with my 1999 escalade. Thought it was the actuator bought a new one installed it transfer case would engage but front end wouldnt lock. Took it out of housing left it plugged in got a friend to go through all the 4wd for me and the plunger never moved out the actuator. Checked my wiring harness which is a four prong ann it had one hot prong like it is suppose to. Traced wires even replaced dash switch same problem. Taking it to local dealership tom to have it checked for codes. I was told it could be the transfercase actuator even though its workin that actuator is what sends power to the front to engage the actuator to lock the differential.

SOURCE: the 4wd in my 1996 chevy silverado 1500 wont work

On the full size, the front actuator is electric, not vacuum.

When in 4wd mode, a switch on top of the transfer case conducts 12 volts out to the actuator. Wire #50 (brown) is the 12v feed, and it conducts to the light blue wire (#900) to the actuator.
When shifted out of 4wd, the switch opens up and no voltage goes to the actuator.

Check voltage at the connector for the front actuator (at the front differential - it looks like a large bullet that threads into the front diff.) If it has 12 volts, the actuator is the problem. If it does not have 12 volts, check the transfer case switch and the power feed to the transfer case.

I'll assume it is the actuator, if the plug to the actuator is getting 12 volts when in 4wd.
The way this actuator works, is it is a sealed chamber that gets heated by voltage. When it heats, the pin in the end swells and pushes a shift fork in the front differential. The shift fork engages a spline on the passenger side of the differential, and boom! you have 4WD.

GM offered an upgrade to this actuator that is a motor instead of a heated device. However, it requires a small harness addition, a spacer, and a new actuator. It is about a $150 to $200 option.

If I were you, I would buy a new heated actuator. They are available at most auto parts stores, and are about $90. They are also on eBay for about $55 plus shipping. These are very easy to change - just thread out the old one, and thread in a new one.

Good luck. The actuator is usually the problem 90% of time but recheck all of the wire harness just to maker sure there is no short before replacing any parts.

SOURCE: What do we do when

P0446 could be a bad purge valve, bad ecm, or wiring between. the only way to know is to have a mechanic diagnose it. It needs to be repaired if you want the engine light off. If you let it go, the ecm cannot tell you if other problems are happening because the light is already/still on.

check that your map sensor has direct (unregulated) vacuum. I don't believe that the purge solenoid can create that kind of problem.

Check engine light code p1676 Chevy lumina Ltz


Trouble Code: P1676 (3.8L V6 VIN K Auto)
Evaporative Emission (EVAP) Purge Solenoid

Number of Trips to Set Code: 1
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
Conditions for Setting the DTC.
  • The ignition is on.
  • An improper voltage level has been detected on the output circuit which controls the EVAP purge solenoid.
  • The above conditions are present for at least 30 seconds.

Possible Causes:
  • Poor connection at the PCM. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.
  • Damaged harness.
  • Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the PCM, turn the ignition on and observe a voltmeter connected between the EVAP purge solenoid control circuit and ground at the PCM harness connector while moving connectors and wiring harnesses related to the EVAP purge solenoid. A change in voltage will indicate the location of the malfunction.

My service 4wd scan comes on. any idea what that


It is called the solenoid sensor, it can keep the truck in a different gear than is shown on transfer case switch. This happened on my chev as well but it wasn't the sensor just a corroded ground cable for the solenoid sensor.
