Chevy equinox. Location power door lock relays .i dp not see them

Did you hook up a professional grade scan tool an check BCM codes ,view live input data for power locks .
Door Lock System Components
The power door lock system consists of the following components:
• Driver door lock switch--Provides a switched voltage signal to the body control module (BCM) for both lock and unlock switch activations.
• Front passenger door lock switch--Provides a switched voltage signal to the BCM for both lock and unlock switch activations.
• Door lock relay--Located in the instrument panel (I/P) fuse block and controls the locking of all doors and liftgate.
• Door unlock relay--Located in the I/P fuse block and controls the unlocking of the passenger doors and liftgate.
• Driver door unlock relay--Located in the I/P fuse block and controls the unlocking of the driver door.
• BCM--Class 2 module which requires programming when replaced
• Reversible door lock actuators in each of the doors
• LOCK/MIRROR 10 A fuse--Located in the I/P fuse block, supplies power for the door lock switches and relays.
• DR LCK 20 A fuse--Located in the I/P fuse block, supplies power to the relays.

DTC B3150 00: Driver Lock Switch Circuit
DTC B3155 00: Right Front Lock Switch Circuit

The relays in the I/P fuse box are not listed because you can't change them so why show then . They are PCB - relays Printed circuit board relays , soldered directly to the circuit board inside the fuse box.

You best bet ,take it to a qualified repair shop. I would say the vehicle has a lose connection somewhere . Ground ,


My bet is that it is a relay or the body control module. ??? Then you would be wrong Take it to a professional before you start replacing parts it doesn't need .

Which door locks aren't working ? Driver an front passenger door locks are controlled by the BCM - body control module ,not a relay . Rear doors are controlled by a relay , door lock relay located in the underhood fuse / relay box . Should show location on the inside of the fuse box lid

As you can see, there is a lock and unlock relay, both.

Door Lock and Unlock Operation
When a door lock switch is activated in the lock or unlock position the BCM will receive a voltage signal on either the door lock switch lock or unlock signal circuits.
The BCM, upon receipt of a lock switch lock or unlock signal, will switch the appropriate lock relay control circuit(s) to battery positive voltage. This will energize the appropriate lock or unlock relay(s). The relay will supply voltage to the door lock actuator lock or unlock control circuits to one side of the lock actuator. Since the opposing side of the lock actuators are connected to ground through the other lock actuator control circuit and the normally closed contacts of the lock or unlock relay, the doors and liftgate will then lock or unlock appropriately.
Three relays are used to operate the lock. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked by itself using the keyless entry transmitter.
Your door locks are controlled by the BCM - body control module (a computer ) . An a scan tool is a must to diagnose system operation . Your best bet would be to take your vehicle to a qualified repair shop . The only way you could try to fix this is by changing parts ! Suppose you find an replace a door lock/ unlock relay an that doesn't fix it ? There could be DTC'S stored in the BCM . Do you know what a DTC is ?

Your

Under the hood in the fuse and relay center.

IT WOULD BE IN THE INTERIOR FUSE BOX INSIDE TRUCK DRIVERS SIDE

1) Your key fob could need a new battery.
2) Your fuses could need checking.

I've had the exact opposite issue with my 2005 Equinox.
My rear door is locked and will not unlock.

check fuse .if fuse good you got a bad ground.

Did you unlock doors and pull handles like to open, then try?
