Talking Re: Greg Smith Power door locks writeup

Just wanted to send a HUGE thanks to Greg Smith! I've been goin' out of my mind for the longest time trying to pinpoint the problem with the power locks in my '87 XJ...until finding his writeup. I actually bought three lock actuators off eBay before finally finding this thread, but they made no difference. Even taking out all 4 door latch mechanisms and cleaning them didn't help (although they did kind of need cleaning and re-greasing).

I think I may have woken up my neighbors with my celebratory shouts after finishing the 20 minute job, but oh well!! That first "chunk" sound of all 5 locks slamming from locked to unlocked was just.......sweet. I was totally amazed that all it took was about $7.00 in parts and a little time!

Greg - YOU ROCK!!

To anyone having problems with this fix, just read Greg's article carefully (maybe a couple of times) and maybe print it out for reference. My install went without a hitch. No problems at all! Worked the first time!! Just be sure to find a good +12V wire and a good ground.

Thanks again, Greg!

Pyro

Re: Greg Smith Power door locks writeup

Pyro, Glad it worked for you. It is amazing how annoying those reluctant locks can be. Yes I danced around and screemed out loud when I finally fixed them after yrs frustration. With so many happy door lock fixers maybe we should start a new club -- the dancing door lock fixers!

Re: Greg Smith Power door locks writeup

I have all of the parts together, harness made/labeled and will be installing Saturday in my '89. I'll be using a new ground point and will pull a fused 12 volts from the battery.

I'll let you know how I make out with the upgrade.

Re: Greg Smith Power door locks writeup

Well Greg,

You're fix worked great. Thanks a million. I hoisted a few Buds to you yesterday afternoon.

I bought the parts from PartsExpress last year on your recommendation and they were great. I used the dual relay connector/harness. I think the problem I had last year might have been that one of the white wires was pushing out of the new connector/harness. I pried the tab out a bit and that locked it in better. It was also too hot at the time and had sweat dripping into my eyes.

If anyone else is considering doing this just use the diagram, follow Greg's instructions exactly and you'll have no problem.

A couple of things I will add that might help someone:

1. The original relays stay in the circuit so don't remove them. I was unclear on this when I tried the install last year.

2. Cut the light green and tan wires on both sides of the connector (close to the connector) in the passenger side kick panel. This will give a little more wire to work with.

3. Use butt connectors to make your connections. Don't bother soldering them (as I tried last year). Too much hassle and not really necessary.

4. Make sure if you are using the 12 volts that is supplied by the red wire in the kick panel that you are getting 14+ volts with the engine running and battery voltage of 12+ when not running. Measure across the battery for comparisons.

5. For the ground I used the 1/4" hex head screw that clamps the wire harness to the floor pan area. Remove the screw, scuff the area up good so that you have a clean metal area, place a star washer between the ground wire connector and the body. Then attach the plastic harness clamp over the connector and washer.

6. I would recommend making the assembly prior to install and labeling the tan and light green wires as to which side of the original connector they will be installed on. Then all you will have to be concerned with is the four lock/unlock connections and the 1 power and 1 ground connection. I installed mine with wire nuts first to make sure it worked then connected it permanently with butt connectors.

I wish I got to this earlier. My 17 year old daughter is a bit lax about checking the doors for being locked and she got her CD player ripped off at school....that's another story. She bought a CD player that was very deep with wire/heat sinks/large external components etc that it wouldn't install into that shallow XJ dash.

Greg I wanted to ask you....are you into electronics etc or are you just naturally proficient with this type of thing?

Thanks again Greg,
Jay in MA

Re: Greg Smith Power door locks writeup

Jay I am happy that you got the fix to work. Those stinking annoying locks can really burn you up . No I am far from an electronic wiz. Just a Govt Atty who needs an outlet from the dailey paper pushing and adversarial battles. So tinkering w. the house and cars is my way to do something to see more immediate value added for my efforts. The locks drove me crazy for yrs. I was determined to figure them out. So after many hours of studying the wiring diragrams and testing the components per the fsm testing procedures I learned alot and came up with a solution that any electronics person probably would have come up with alot sooner. First order of business when I retire this summer and move to the new house w. a 3 car garage (13 ft ceiling) w. lift (!!!) is to take an auto electronics course at the local community college to get more proficient in all the other auto electronics stuff. Enjoy your now working power locks. Greg

Re: Greg Smith Power door locks writeup

So what do you do with the relays on a 93? My rear passenger door doesn't like to unlock very well and I've already cleaned it. The drivers rear door is almost as bad, but the rear hatch works great. What do you do with a 93?
Thanks,
Mike Harris

Mike, Sorry but they changed the power lock wiring starting in 1991 and my only experience and thus the relay (additional relays) fix I suggest is for the pre 91s. However, I know a little about the rewire (they changed the wire colors also)they did and I suggest you test the system by checking the input and output output voltage of your stock relays in the kick panel on the lock and unlock circuits. Then check the voltage your are receiving at the actual lock motors in question. You will lose some voltage through the system to the lock motors but the questions is do you lose too muck to work the lock motor. Generally in my experience the lock motors should work well w. at least 8 - 9 volts. If your have less than that and have good volts coming out of the relays then suspect a bad wire splice or wire somewhere between the relay and the lock motor. Since more than one lock motor is involved I would suspect the relay, connectors, splices or input voltage. Good Luck. Greg

Re: Greg Smith Power door locks writeup

I did the now infamous 'Greg Smith door lock mod' on my 87 well over a year ago and have been very happy with it but only recently did I come to realize that now my remote rear hatch lock now works again too. .
..and all this time I've been using my key in the rear hatch not knowing that the door lock button was triggering it unlock/locked.

Your a celebrity Greg!

Re: Greg Smith Power door locks writeup

quick question for greg or any other electrical guru...

in my quest to find the problem with my headlights, taillights, brakelights not coming on (another post) i've been tearing into the area near the fuse block at the drivers side on my 89 xj. seems like the previous owner tried to do the door lock mod on the *drivers side*, not passenger side, however, did it completely wrong (well, it didn't work and it was wired up differently). here's how they did it:

the green and white wires were spliced at the drivers side. there were 2 relays, which i will refer to as relay A and B.

relay A-
30-white wire to switch
85-daisy chained to power, 87, 87 from relay B, AND 86 from relay B
86-ground
87-see 85
87A-white wire to lock

relay B-
30-green wire to switch
85-ground
86-see 85 for relay A
87-see 85 for relay A
87A-green wire to lock

needless to say, it wasn't working, but im wondering if there is any logic in this? would there be a benefit to trying this out, wired "correctly", of course, at the drivers side?

i plan on removing it and reusing the relays at the passneger side this weekend.

thanks!

Re: Greg Smith Power door locks writeup

I wonder if anything has been changed on the passenger side wiring

Me...I would try to first put the driver's side back to its original configuration. Try the locks at each switch to see that it at least tries to trigger each door lock when asked. Once it has been confirmed that they do indeed try to fire as asked I would install the relays and sockets into the passenger side wiring.

Good luck,
Jay in MA

Re: Greg Smith Power door locks writeup

I just finished this fix yesterday, now all the locks work.

Thanks Greg.

The hardest part was getting the screw for the kick panel back in.
