I have an 87 GT with power locks, but I must lock/unlock manually or hit the button 7-8 times to get them to lock or unlock completely (moves a little with each push, takes multiple times to get them in position).

Any way to fix without pulling the door apart?

Thanks,

Tim

You need to pull the door panels and clean and lube the mechanism and rods.

For most Fiero owners your problem is considered "Normal". To get them to function properly you will have to do a complete clean and lube on the lock system.

Doesn't Rodney offer something that helps the power locks work better?

No, that is for faster power windows.

Mine did that too.
I was wondering if there are any connectors in the power line to the lock solenoids that could possibly be building up carbon or corrosion. Maybe if they were cut out and soldered?
Has anyone inspected the wire harness to the solenoids themselves?

I've some success with just spraying some WD 40 down into the locking mechanism. I don't remove the door panel . Spray the WD using the straw thingie down by the rear edge of the window. You can see the levers there.

Exactly! That's how I do it.

Use a small LED flashlight inserted into the dew strip, keeps it seperated so you can see the lever and aim, douse it with your favorite PB blaster while manually moving the lever. You'll see that lever, no doubt, spray it down good, might take a couple of dousings to get penetration. I also get the stray thingy up into the latch as well as the door lock followed up by lock-eaz, have a towel handy.

Oh I love the smell of PB Blaster in the morning,,,,

I doubt it's wiring related. Lube is the way to go. I used white lithium grease while working the lock mechanism. I also lubed all moving points. Both locks work perfectly now with a quick poke of the button.

i used the previous mentions PB blaster to clean them used the white lithium to lubricate. 2 years now and i only ever have to hit the button once. unless its super cold then maybe 2-3

Thanks for all the great info! I'll be hitting the locks with PB Blaster and then lube this weekend. I greatly appreciate the suggestions!

I need to do the same with the locks on my truck... which you may note trivet, I bought a few years back from Al Serra in Grand Blanc (just east of the I-475/Hill Rd. exit)

Doober,

I used to work in Flint, and spent a lot of time (and money) at Assenmachers bike shop in Swartz Creek back in my 'yute'...

Now I spend all my time and money on my 87 GT

Ha! My cousin worked there in the '90s, it's where I got my Schwinn that I still own (rear wheel needs truing/replacing). My dad still works at the metal fab plant in Flint.

mine did the same thing and when i took the iner door panels off, i found that the rod that slided forward and backward was rubbing on the metal frame (both doors). i just clearanced them by bending the metal a little bit. then i cleaned and lubed them with a little white lube. wd 40 and others will dry up eventually.

Isn't there a write up on this? I swear I saw one a few years ago. I can't find it now.

EDIT: This is what I was looking for. I thought this was on the forum somewhere, but apparently not.

That's a great article, and it's something I need to address with me '88 GT. I hope to go at it while also replacing the dew wipes, all at the same time...

I also did mine last fall without removing the door panel. I removed the top screw on the weather stripping at the top of the door and shot PB blaster in through there and into the latch mechanism while repeatedly operating the lock manually. When it loosened up I lubed it with Fluid Film.

Now the doors locks are one hit wonders... unless it's pretty cold out lol. I was happy this spring when I put the battery back in and hit the buttons and they worked right away.

You might try using Tri-Flow lubricant. Sorta like silicone, oil, and WD40 all mixed together. Will last a long time, also works well on bike chains. Be sure to shake the can well before spraying!

I take it this is being done with the locks still mounted to the door and juat the panel off?
