Awesome works, Robert! Volvo cars are some of the most serviceable, modular, and well built cars I’ve ever mechanic-ed on! On other makes, that motor would’ve been hardwired in. In the shop I help out at, whenever a car has some ridiculous, unfortunate or costly issue, I often retort “they should’ve bought a Volvo”. I love these cool little cars. They’re like clocks, but less tedious.

Worked a dream! Took less than an hour. I used a half inch wood chisel to remove the motor cover: popped off, undamaged, in seconds. On the driver's door lock I had to put the key in the lock to align the lock mechanism. Used a strand of wire from a battery cable in an 's' shape to replace the thermal switch - quick and easy and worked fine.

Hi Robert, Yep, my 99 V70 has this problem too. I was looking for an actuator at the salvage yard. Never would have imagined this may be the source of the problem. I do not have a remote key, but it may at one time. My passenger door button goes down when I hit the lock button, but you can actually still open it from outside. It won't pop back up when I hit the unlock button. Thanks again!!

[@RobertDIY]

Gypsy2Go I'm looking into a remote lock system that should cost less than $20 to install. Stay tuned.

[@mds2465]

Nice job Robert! I didn't realize it's something as simple as that keeping the doors from unlocking.

[@RobertDIY]

From what I understand the head light wiper motors have the same issue causing them not to park. Michael Sackstein

[@mds2465]

My Saab had those things. Fortunately the motors never had a problem but I did have to change the wipers and they cost $20 a piece. And the only place I could find them was at my local Saab dealer.

[@RobertDIY]

Dang. I think they are $7 a pair on some of the Volvo sites.

[@mds2465]

I'm sure I could've found them somewhere else for less. I didn't think to order them at the time. Honestly Saab parts are expensive pretty much anywhere, and now that they're bankrupt it's going to be almost impossible to find them.

[@mds2465]

You know the funny thing is my dad almost got a Volvo instead of the Saab, and now looking back on it I really wish he had.

[@hotchalupa]

Amazingly thorough video!! Thanks, Robert!!

[@RobertDIY]

hotchalupa Thanks for watching.

[@Baxtexx]

Thanks, this helped me fix this problem! Word of advice. Make sure you connect the cable harnesses to the lock in the correct way. I accidently switched them and burned through two fuses. 😊

[@RobertDIY]

That should not be possible because they are keyed.

[@Baxtexx]

@@RobertDIY not mine, they were identical but had different colors, black and Grey. Also I had some kind of aluminum plate between the lock and the door that you didn't have in your video. Would have been easier to access by removing it but then you would have to loosen the window engine etc so I ignored that. But again, I switched the cable harnesses back to the correct position and now everything works fine! My car is a 99 S70 so maybe they changed something on that model.

[@RobertDIY]

could be.

[@martyjohnston700]

I also burnt a fuse by reconnecting the 2 plugs the wrong sockets during a test before reinstalling on 1998 S70

As it turns out, the rotating lock actuator pin wasn't inserted into its receptable on the lock assembly. An easy fix after watching these instructiond.

Great video Robert. My driver latch functions properly electrically but latch part that grabs body holder to keep dooor shut has something internally sticking so door will not latch properly (latch does not engage. if I pull door handle and release from fully extended (so door handle kinda slams back) something in mechanism clicks and door will close shut as it should. Do you think this can be fixed with lubricating something in mechanism? Thank you for advice. All your videos helpful.

Nice mate! Love your vids, helped me so much! Thanks for that...

[@RobertDIY]

You are welcome.

[@GWBridge]

Hi, Robert. I enjoy your videos. I can see the thermal protection device becoming over-sensitive after years of use (circuit breakers can do that also), but is there any chance that the motors are heating up due to dried up lubricants or something. If the mechanism is no longer moving freely, the excessive current could heat the motors up. Just a thought.

[@RobertDIY]

Nope.

[@GWBridge]

Okay, I believe you, Robert. I used to work with x-ray machines in hospitals that have a lot of moving parts that were connected to motors. One machine had to transport a loaded film cassette quickly into the radiation field to take an x-ray. There were two circuit breakers, one for each direction. These would eventually become overly sensitive and trip when they shouldn't. You could spend all day trying to find a fault in the system that was blowing the breakers, but it was the breakers themselves that were bad. They also protected the circuit by sensing heat (due to current through a resistance). My locks are sticking in the V70 that I just bought, so I was wishfully thinking. I don't mind the mechanical stuff, but I hate dealing with door panels! ;-)

[@cmendoza1094]

Awesome detailed video. One word of caution , you can fit the electronic connectors to the door latch motor backwards if you aren't sure which way they go. I did and at first it simply didn't work on the one door. But now none of the door motors respond nor the trunk latch. And the car won't start either now. Go figure , anyone run into similar issues?

[@RobertDIY]

+C Mendoza nope. You probably triggered the alarm somehow.

[@cmendoza1094]

The SRS light would flash and no other light when the key was being turned. I reconnected the door latch and replaced the 20 amp fuse number 6 for the central locking/alarm unit . Works now, like new. Thanks for the speedy response too. Keep up the good work.

[@RobertDIY]

+C Mendoza good deal.

Thank you My problem is a bit different. The motor works and the lock button goes up and down but the door does not actually lock. Click button up then click button down but the door will always open from the outside. I'm stumped on that one.

[@RobertDIY]

Bad latch

[@subtracktmusic]

Hi Robert! I have a 94 850 that has a few door lock actuators on the fritz. I opened up on today and tested the motor and it seemed to be running OK, also tested with the 9v plugged in to the two wires in the wiring harness which was also OK. For some reason, the motor doesn't function when plugged into the vehicle. Windows work as does the trim light on the door, and no obvious damage to the harness. I pulled the #6 fuse which looked OK and my last bet Is the Door lock relay under the dash. Any chance that it could be busted even though 2/4 locks work?

[@RobertDIY]

Maybe it's weak and doesn't pull hard when the door latch is putting pressure on it.

Nice job! One question - I have a 2011 C70. The driver's door did all the weird stuff - like unlocking and opening itself while on the highway and then recently the driver's do inside handle stopped opening the door. The cable is still attached and is pulling so I assume that it is something in the latch. Should I just replace the latch or do you think I could repair it?

[@RobertDIY]

Not sure. It should only open mechanically so there may be something broken internally. You didn't wash the vehicle in cold weather where it could have gotten wet and froze up?

[@SonnieAdams]

Hello Robert. I have a Volvo 1998 S70 and need some advice on parts, I need a gear stick and that item is super expensive. I was thinking of pick and pulling some parts. My question is how can I find a savage yard that has my make and model? I live in Albany GA.

I usually open up my Google maps app and type in pool and pay salvage yard. Then I look at the results for the one that say Pick-n-Pull U-Pull pull and pay stuff like that. Then you can go to their website and look at their inventory.

Going to give this a shot on my 98 V70. Useful info! Have you ever tried QBond on something like the lock motor casing? Its basically super glue on steroids and fixes most materials. Cost me about $17 at the car parts place but one box had lasted all year. It's a must have for me as I work on older cars as well and some of the parts are getting hard to find.

[@wrybread]

I tried this repair but wasn't able to successfully put the motor back together after removing the thermal switch. I was admittedly a bit ham handed when opening the motor up. But it occurred to me: with the two S70's I've owned this issue has only ever been with the rear door locks, the front locks have always worked just fine. So I wonder if the front door locks don't have this annoying thermal switch? I pulled a couple of front door lock motors from the junkyard and installed them in the rear doors of my S70, so far they're working great. And it's a lot easier than the electric motor surgery method here. To me at least. Assuming you have a junkyard near you of course. I've been meaning to pull a couple more front door lock motors at the junkyard and pop them open and confirm my theory that they don't have thermal switches. Does anyone else know by chance?

[@RobertDIY]

They have them. I didn't realize that the front door latches will bolt into the rear doors. 🤔 You will loose your child safety locks but most people never use them.

[@wrybread]

@@RobertDIY I'm only talking about the little motor, which looks identical, and I don't think affects child safety locks? I don't know how those work though so maybe I'm wrong. But it looks like the exact same motor. I haven't opened one up to check for the themral switch. But odd that I've never seen a front door with the issue. Maybe people just replace those more often?

I believe it is against the law to destroy currency so I would not do that. LOL Copper or aluminum should work so you have a lot of material options. lineartechbd1600

[@ChEsperado]

Robert Diy, aluminium oxyde itself instant, and the oxyde is alumine, a very good isolant. Don't use aluminium for electrical contacts.

[@JuanHernandez-uw3ku]

is putting a penny for the electrico connection good to

[@RobertDIY]

+Juan Hernandez Probably to big. They are not copper so, not sure how good it will work.

[@JuanHernandez-uw3ku]

I cut the penny to size and put it in and now it works perfect thanks Robert for your help

[@RobertDIY]

+Juan Hernandez don't tell anyone. It is a violation of the law to destroy currency.

[@egria]

First thing is to mechanically rotate shaft with fingers before doing anything else.If it works both ways that operation would help. Otherwise will not, something else maybe plastic gears are broken.

😒

[@robtheknob7791]

I did everything in the video and the motor just won't work, is there a replacement for the motor I could order?

[@RobertDIY]

Is it the same for trunk lock on V70??

[@RobertDIY]

No, you likely have a broken wire somewhere or a bad actuator in the trunk.

[@Vikleph]

@@RobertDIY I am able to open the trunk by key. But with remote it only makes clicking sound and doesn't open..

[@cswoup5498]

HELP!! Just did all of this and now the 1998 s70 wont start. All interior electronics come on but nothing from motor, not even an attempt to turn over. What happened??. I did not disconnect from battery prior to doing work. Car now dead in driveway......

[@RobertDIY]

Yikes!

[@RobertDIY]

glad you found the bad fuse.

[@cardocontheisland8395]

is there an updated motor number? I see 27340-394935 but can't find a match. Thanks for a great video.

[@RobertDIY]

I have no idea.

[@alexanderschonfeld5879]

Hello Robert, it is absurd that Volvo would use a motor where a simple solenoid (or pair of solenoids working push pull) would work far more reliably. I have a 2000 S70 where both rear door lock motors got lazy. To top off that stupidity Volvo placed the finger stems at the back so to reach the stems from the front you have to stretch far to reach. These motors are just low priority on a long nuisance fix it list on a car that's hanging in by a thread after 254000 miles. The most annoying is that everything (entire body) squeaks and crackles even on a smooth road

[@RobertDIY]

they are getting old. the good thing is that they can be fixed.

[@jayberry6397]

I used a penny and a grinder. Just make sure the penny is pre 1982. Lay the old waffer on the penny, and trace it with a pencil.

[@RobertDIY]

Yikes! I think that may be against the law.

[@jiggyjc5587]

I fixed my driver rear door and it’s working fine except the door is unlocking when I push lock and locking when I push unlock. How did I manage that?😂 The motor only seats one way.

[@RobertDIY]

Somehow got the polarity reversed. 🤔🤦🏾‍♂️🤷🏾‍♂️

[@danwilliams9155]

My front passenger door looks like it locks but really doesn't. Any ideas?

[@danwilliams9155]

Sorry 99 s70

[@RobertDIY]

+Dan Williams Bad latch assembly.

[@danwilliams9155]

First of all thanks for getting back to me. I think I Have the opportunity to get a used one at the junk yard. A simpler fix I guess?

[@RobertDIY]

+Dan Williams Should be.

[@dchampion5576]

Why doesn’t just cleaning the metal wafer or chip work?

[@RobertDIY]

I have no idea.

[@Anonsage3]

I think ill just reach over and unlock the doors manually from inside lol. this does not look fun.

[@RobertDIY]

LOL

[@iamenough6958]

Just want to use my key to open the car door 👁️

[@RobertDIY]

what does that mean? Your key doesn't work?
