drivers power seat not working?

[greenbeast]

Considering a 93 80 series but the current owner has front seat unplugged. He says it just wouldn't run so seat is set where his wife would ride. As you can prob. guess we dont have same bodies. Is it easier to find old seat or purchase new motors and replace them?
Is there a common problem with these where I could start? The owner has no idea why it didn't work and has had it unplugged for several months!

The exact same thing happened when I bought mine - seat unplugged.

I would bet $100 it is not the motors at all, there is a nylon worm gear in there that gets stripped, so only one side of the seat adjusts, and the seat torques at an angle as a result. The part is like $80 from toyota a very easy to fix yourself if you remove the seat. Very first fix I ever did on my 80.

I think I did a thread on it a while back, but here is one I searched and found.

Yhatzi! The gear on that page is what goes bad.
Original poster, easy check:

Plug in the seat, and try to adjust. if it moves, but at an angle, then those gears are what you need.

I have a similar issue or maybe the same.

Neither driver or passenger seat go forward or back. They do however recline and go up and down. There is no noise coming from the motor when trying to adjust forward or back. They are plugged in. Drivers side is missing cap, passenger is not.

Does this sounds like a cap/gear issue that can be resolved by the Gamiviti parts? Looks like there is 1 cap and 1 gear per seat so for $30 I could fix both?

Thanks,
Eric

Most likely, sometimes they are stuck good...that motor can not move....start with the passenger, make sure that the front of the seat is raised to its highest before you remove the seat. There is a plastic cover with two screws that you need to access, and can only be done with the front part of the seat raised to its highest. Once you see the working mechanism, check out this link... https://forum.ih8mud.com/80-series-...wap-broken-seat-missing-cap-issue-pt-2-a.html

had problems with mine, it would go forward but not back, I took it apart and the issue was the electronic switch module, got a used one and replaced and now works fine.

 

[AustinFJ]

Thanks for the input. I emailed the guy at Gamiviti and have the parts on order. Fingers crossed $30 fixes both my seats.

Let me know about the fix? I passed on the 93, instead bought a 96 whose seat goes at an angle and is stuck all the way back. Not good for the wife to drive it but than don't want her driving it anyway!!!!

Will do, I hope to get around to it next week.

When doing the gear swap do I need to replace both gears on the seat? I have replaced the one shown in the instructions, but there is no mention of the other gear. Tried to press it off and it did not budge. Don't want to break anything, so figured I would ask.

Thanks

I had the same problem. This is a really expensive part for what you are getting but a fairly easy fix.

I have the same issue with the passenger seat. The inboard gear stripped. The seat will not move except when I am under it with a 12mm wrench.
The leather on the driver's seat bottom area gave up at the same time. It is torn now.
I am thinking about a pair of Celica or Camry seats from the salvage yard. I did it for my wife's Toyo wagon. I took a pair of seats from a new Celica, and welded the old mounts on. The car is so much more comfortable! I may do the same for the LC80.
This opens up a whole new set of options.
There are a whole slew of man-types. I an all of 160 lbs. A light, wiry Irish guy with a lower back concern. Some of you may be 225 lbs. and a lot taller than I am. There is a chair for every driver.
It is a simple matter to weld the original mounts onto any Japanese seat, and fit it into the truck. It's not that hard!
In the second row seating area of Jill's 4wd Toyota van, I have a pair of Mazda Protege front reclining seats mounted on Mitsubishi Montero shock-mounted bases, in the back seat area. Re-mounting seats is not high rocket science. It is not that hard to do.
The only catch in the 80 is the seat belt attachment on the inboard side of the seat. Any replacement seat has to have that seat belt location on the inboard side. Other than that, a replacement seat could come from any Toyota, Honda, Nissan, Subaru, or other Japanese car or truck. I am thinking first of the Celica, Camry, or Cressida lines.
The original leather seats in the 80 are very hard and uncomfortable. I have often seen this singular complaint on this site. I will see what I can do. If any of you can come up with a suitable seat before I do, post up.

I'm about the same build as you Brian and replacing the bottom seat cushion made a world of difference. I have the same back concerns as you and I'm very content with this seat. Just got home after a 5,050 mile road trip w/o any back issues.

What I'm curious about is that the car seats are typically shallower than our 80 seats so I'm guessing you'll need to build up the frame a bit.

using search this may be the most recent and appropriate thread to ask my question. sorry for the re-vive if that's not the case.

my new (to me) '93 showed up. drivers seat only moves forward (ugh) passengers neither forward or back (both thigh areas move up+down and seat backs recline and raise). on the driver's seat, again, slide forward works. But when pressing slide back:

1) with the head-lights off, the "A/T oil temp" lights up, and the "low oil" lights up, and the "discharge" lights up (all dash lights are normally, well, normal) and the dome light/head lights dim slightly while 'under load'. all go back to normal when not trying to power the seat back.

2) with the head-lights on, only the "discharge" lights up, and the dome+headlight dimming.

so, does this sound like a gear issue (that will sadly only go one way) or the electronics (like guppie mentioned) causing these symptoms?

also, any tips on where i could manually turn a bolt and move the seat back? it's scary close to the steering wheel at this point.

thanks.

look for the white plastic cap that often comes/falls out and affects the fore/aft movement of the seat. A cursory search should reveal some pics of this little bugger.

 

[hakalugi]

thanks. i'm finding pics of the spare parts / cap kit. should it be here where there is a hole showing an off centered shaft?

also, can i manually move the seat back somehow? (taking the seat out/unbolting and turning the shart/mechanism somehow?)

yes, but if you're going to take the seat out, might as well fix it since you're 75% done just by taking the seat out.

jlg - 10-4, just incase it takes a while to source the parts i might have to do it, i can barely fit...

I don't know if this will work or not, but the white cap simply keeps the shaft pushed in while it's rotating. Could you simply push the shaft in with your finger while you operate the switch to move the seat fore/aft? Just a temp measure but it may move the seat back to your desired location. Just a thought. Report back with what you find out.
