    I had both problems to contend with and had to replace fuse and then 2-door actuators. I did locate the relay directly under the steering column where 2 banks of relays are attached in a major cluster of connectors. 1 bank has 2 larger relays(these are not for door locks) the other bank has 3 smaller relays of which only one is for the door locking operation.
    Thanks a bunch for leading to a solution, it should also be noted that 2 different types of relays were shown depending on mid-year production changes so check yours before replacing!

If your door locks are not working and your cigarette lighter is also not working the fuse is burned out. On my 2001 astro van it is #13 in the fuse box under the steering wheel. I have replaced mine and so far no problems. Good Luck.

There are two relays for the power locks: one for lock, one for unlock.They are located in the central circuit/fuse junction box. If ANY of the power locks are working properly, the relays are NOT the problem.
To troubleshoot...check voltage at each actuator that's not working properly. Disconnect the actuator and connect a voltmeter between the two wires in the vehicle harness. While operating the switch in both lock and unlock positions, the voltmeter should indicate battery voltage in both positions. If it does, the actuator needs replacement.
Good luck...I hope this helps.

Need to know where the windshield wipers relay is located on 2002 chevy astro

A Chilton/Haynes manual for your make/model/year will give you the exact location. They can be purchased at parts stores. My best, off the top of my head guess, would be in the fuse/relay panel under the hood on either the firewall or inner fender well.

Dear fellow Elantranians,
I am an original owner of a 2002 Elantra (w/anti-theft module/ETACS), and have wrestled with the same problem for months: remote will unlock, but not lock doors.
The answer to the problem, at least in my case, was a door lock relay (Part #95250-2D000) located behind the center dash, to the right and below the radio and heater/AC controls (removal and replacement reasonably easy). A simple removal of one bolt and a wire connector, and the little devil is exorcised. It's been working without a hitch for more than two weeks, and expect it to continue for eleven years as the original relay did. I purchased this relay from a local salvage yard for $14.00, but a Hyundai dealership (, will sell it to you for $36.00.

Looking for location of bcm on 97 astro van dash

The BCM is located immediately above the heater controls inside the dash on my 2004 Astro. I know it controls the headlights and locks but not gauges. Haynes says the gauge fuse supplies it power....but I'm not going to bank on that one.

My 2002 astro van door locks will not fully operate. I replaced the door actuator on the passenger side, but now the driver's door won't work, the hatch is stuck shut on one side, the headlights will...

On repairing door locks first check the cigarette lighter and see if it works, the door locks gets it power on the same fuse. If good,you then need to check if 12VDC is at each of the actuators when pressing the switches for the locks. If no power is not at the actuator you should suspect the power lock relay to be defective. This relay is located beneath the steering column within a major cluster of connectors and is located within a bank of 3 relays located within a covered housing. These 3 relays are identical and you can temporaly reverse them to see if this will solve the problem. If it does, GM's part # is RY-232. Can't help you on the rest.......sorry!
