I have a '99 Suburban 4x4 with 454 engine. What I think you are looking at is an electrically actuated switch with a vacuum source that when actuated by the A/C system allows the vacuum to operate a servo in the heater hose to the front heater core(probably rear as well), bypassing the heater core for more efficient A/C operation. Hope this helps! Mike www.thebltband.com www.myspace.com/nekansasdrummer
Usually a brown wire located at the firewall next to the power steering booster. To the left of the booster looking from the front of the vehicle.
If you open the hood and stand in front of your vehicle and look straight to the "back wall" of the engine compartment, you are looking at the fire wall. The firewall is the engine side of the front passenger compartment.
You need to be more specific. as in what solenoid are you looking for?
If you are looking for the starter solenoid, it is attached to the starter.
looking at the motor from the passenger side fender..number 1 cylinder is closest to you on the left..firewall side
Under the hood, passenger side of firewall, down low. It may not be visible looking from above.
On the chevy solenoid, you may be looking for the shift solenoid, and wondering where it is. The shift solenoid on this car is located inside the motor.
Looking at the engine, passenger side on your left, drivers side on your right, the cylinders are numbered 1-2-3 front to rear on the passenger side and 4-5-6 on the drivers side. Cylinder number 3 would be closest to the firewall on the passenger side.
THAT'S THE HORN RELAY
Never really looked at one that new but in the two trucks I have they are located on the firewall all the way to the left (passenger side). Its a round looking thing.
Im not sure what solenoid you are looking for but there are a set of them located behind the trans pan.
All I've been able to find is the description, "engine compartment, passenger side firewall", but it's not there on my (Canadian edition?) 92 Accord. Still looking.
On a Prelude 91 Si, you can find the MAP sensor by looking at the black box which is mounted on the passenger side firewall. You should see vacuum lines that run to it.
What kind of "diagram" are you looking for?If you are only looking for its location - - it is located above oil filter on passenger side of block at the rear close to the firewall.
Looking at the motor it is right behind the Exhaust. The Exhaust is above and below the starter and solenoid.
If you are looking to active your firewall on a router, go into your router administration panel. Find the routers firewall tab and make sure it is enabled.
Under the dash board on the passenger side. You can find it easily by looking for two hoses (under the hood) that connect to the heater core right at the firewall.
when looking under the hood from directly in front of the car, it is on your left hand side toward the back. there is a plastic mold over it, but it is right against the firewall on the passenger side.
The firewall is the partition between the engine compartment and the cabin, you are looking for the side of the engine that faces the firewall or windshield.
passenger side on the firewall underneath the black plastic wiring cover, aluminum cylinder and low pressure valve. takes lots of looking and if amateur then have a pro do it
looking into at the engine from straight ahead, it will be to the right and lower inside the housing. it will have a grey pigtail on it.. about 3" away from the motor.. passenger side firewall.
It is located on the passenger side near the fire wall on the big canister looking thing. Mine has a black cap on it. Just follow the line to the firewall and you will find it.
The powertrain control module passes through the passenger side of the firewall. Looking in the engine compartment, you can see where the wiring harness is bolted to the end of the PCM. The body of it is inside behind the glove compartment.
Standing in front of the grille and looking underhood from the grille area - it's located on the firewall just about directly below the hub on which the passenger's windhsield wiper turns.
To the right of the battery, when looking at engine.
