Where is the door lock relay on my 1991 gmc vandura?

Power locks stopped working recently - pushing the lock button down makes a clicking sound similar to a turn signal noise- making me think that it is the relay. the 30A fuse is good and when testing, actually popped of all the locks up (to unlocked). Bought a relay and replaced the one at the bottom of the fuse panel by the brake. No fix... any help would be great!!

The relay makes a clicking noise when you press the lock button it's not the relay that's the problem. You may have a bad lock motor or what it's called a solenoid. When it's energized it moves. The problem is the get wet or dirty they jam up and stop working. So if you know for sure it's getting power or not getting power. Could be the lock switch could be the issue also. Removing the door panel and test the solenoid first to make sure that works then can test wires or fuses.

SOURCE: Ford F150 Pickup 2005 power doors unlock but will not lock

I had almost the identical problem on my 2005 F150 FX4 Extended cab last weekend. The power door locks would not lock using the keypad, remotes, or door buttons. Almost all other functions worked correctly. The doors unlocked, the radio delay functioned, and the interior lights dimmed. When I used the remote the horn would beep twice indicating that a door was open even there was no message on the message center that a door was open. When I used the keypad or remote, I could hear a soft click from behind the seat. I think it was coming from the body security module or body security module - whatever Ford is calling it this year. I pulled the fuse for the Power Door Locks(BSM). As I removed it, I heard a soft click - sort of like a relay resetting. It may have come from the VSM/BSM. It may have possibly been a stuck actuator releasing. I don't think so. It wasn't that load. In any case, everything is functioning correctly now.

SOURCE: Turn signal continues to make the clicking sound

I had the same problem, I found the post quoted below and fixed the problem in about 1 hour without having to replace any parts. Hope this helps!

(I can't seem to get back into the link but had copied the answer - the original link is: http://www.allaboutauto.us/2007/04/07/1999_chevrolet_blazer_turn_signal_clicking_noise.html)

"I had this same problem and fixed it myself. The problem is caused by the contacts rubbing and releasing small particles which conduct small amounts of electricity and cause the flasher relay to click. From a GM Goodwrench mechanic.

Disconnect Battery Before doing this.

You need to remove the turn signal arm from the steering column. This may seem difficult but it really isn't. Separate the top and bottom covers. Find the screws and remove the switch. One is located behind the column and requires some dexterity to get out. I used a Torx bit on a 1/4 box wrench.

The difficult part is separating the switch to clean the contacts. Take your time and you can figure out how to separate the switch. If I remember right, the switch separates and then the emergency signal switch slides out. Also, pay special attention to the way the rotary wiper delay switch is set into the switch.

Once you can see the contacts, clean them off of all lubricant and metal pieces. I would hesitate to use Isopropyl Alcohol for this because off the plastics involved. I just used lots of Q-Tips and a lot of patience.

Finally, get a good Dielectric (non-conducting) lubricant from auto store and cover all contacts with a thin layer. Put the switch back together, reinstall and test.

This took me about four hours to repair. Because I took my time and did not force anything. Once I figured it out it wasn't that hard. The hard part was the rotary delay switch and how it was set into the switch.

I figured if this didn't work, I was going to have to replace the switch anyway, so what the hell. Just make sure your local auto parts store has one of these available if you screw this one up.

Did this about four years ago and problem has not returned since."

SOURCE: 2006 BMW 323i Passnger Door lock will not lock / unlock w/ remote

Replace fuse 57 (15 amp) then disconnect battery and wait 30 to 45 minutes before reconnecting the battery.

My 2006 BMW 325I had the same problem with the door locks not responding. I checked all related fuses and found #57 (15 amp) was the only related fuse blown. I put in a new fuse and it still would not work. I then disconnected the battery for a while then once I reconnected the battery everything worked fine.

I believe I blew the fuse while repeatedly pushing the unlock button rapidly while walking across the parking lock to the car. I suggest only pushing the unlock button only once or twice.

12 Acadia. Power door locks and heated seats stopped working. Doors switches and remote don't work. Pushing unlock you can hear the relay click. When you push it to lock there is no sound.

Door Lock System Components
The power door lock system consists of the following components:
• Driver door module (DDM)
• Passenger door module (PDM)
• Door lock relay--Located in the instrument panel (I/P) fuse block and controls the locking of the rear doors.
• Door unlock relay--Located in the I/P fuse block and controls the unlocking of the rear doors
• Body control module (BCM)
• IP BEC
• Reversible door lock actuators in each door

Driver and Passenger Lock System Operation
The front power door lock switches are integral components of the driver door module (DDM) and passenger door module (PDM). The switches are two-position normally open rocker switches. When placed in either the lock or unlock positions, the switches provide a direct input to the DDM or PDM. The DDM or PDM monitor these inputs and send a LAN message indicating a change in the switch position. Modules, that activate the power door lock motors, receive the LAN message and activate the motor in the appropriate direction to lock or unlock the vehicle doors. The body control module (BCM) upon receipt of a lock or unlock signal will control the rear door lock or unlock relays and also send a LAN message to the DDM and PDM to perform the commanded function.
The modules that activate the power door lock motors are:
• DDM (driver door lock actuator)
• PDM (passenger front door lock actuator)
• BCM (both rear door lock actuators)
The DDM and PDM are directly connected to the respective door lock actuator through the door lock motor lock and unlock circuits. Once a door lock or unlock request has been received, the module will supply battery voltage to one side of the actuator and ground the other, causing the doors to lock or unlock.
The rear passenger doors are controlled by the BCM through the rear door lock/unlock relay which is incorporated onto the printed circuit board in the LH BEC. The BCM controls the unlock relay by providing ground to energize the coil and controls the lock relay by providing battery voltage to energize the relay coil. This energizes the relay and allows voltage to be applied to either the door lock motor lock or unlock circuits. Since the other side of the door lock actuator is connected to the normally closed contacts of the opposing relay to ground, the doors lock or unlock.

Saturn ion door

on the far right is where the location of the door lock relay.
this could be the problem however there is also in the same area a door lock controler.
could be one or the other ,most relays are the same in a car.some times you can switch places with one relay with another relay in the same general area.you might have to drop down the glove box to access these relays or controler.
because of the clicking sound my bet is on the relay, most cost about ten bucks at any auto parts shop.
good luck,Gary
