when I lock the door on my 89lx with a key it turns stiff, BUT when i unlock it with a key it turns easy, should i worry about it yet?

I just hate to tear off the door pannell and maybe never get it back right

thanks, 89llx
 
when it stops working :D

a word of caution tho, on a hatch that i flipped(not like rolled, bought cheap and sold), the actuator was junk and you could not lock or unlock the door period, i took the junk one out and just left it with no actuator, but if you were stuck for a few days without being able to lock the car it would definitly suck

sometimes when it stops working the door will not open,,,that makes it hard to get the door pannell off
 
What is the concern with removing the door panel? I'd replace it now since you seem to like using the key to lock the door.
 
I might be hesitant if the door panel has never been off ever. The vapor barrier would be pristine, etc. Otherwise if someone else has been in there before, I'd go for it. It's not tough but sometimes the trees are old and break.
 
I could not lock the DSide door when I got my car but the pass side worked fine. I got a replacement cheap actuator (they didn't even send me a new rivet). I discovered I had to shear the aluminum rivet holding the motor on with a chisel (no problem) on the outside of the door. Removed the actuator easily then. Tested the new one and it worked twice and quit. Good thing I didn't buy a separate rivet!! I just left it off since I can lock my door just by pushing the button down and closing it and the passenger side still works off the power switch.

My 84 and 86 both have to be key opened anyhow so I never feel the need to fix it now. The passenger side would drive me nuts tho' and being convertibles I rarely lock them anyhow.

**Later I found a guy in our yellow pages who will come to my house and repair/replace any window or lock mechanizm for a modest price. He knows how to carefully remove all panels, water barriers and has the correct tools and parts to finish the job which he guarantees for 12 months. I won't be doing any of those inside door jobs again so long as he's still around.

yes that is the problem the car has 60xxx miles and they have never been off
, so like i was saying when i lock it with a key its stiff, but when i unlock it with the key it unlocks easy, is it geting ready to screw up, or should i just leave the virgin panel alone?

thanks

Don't waste your money on door lock actuators from some expensive Mustang specialty store. There is a better way...


Follow this link to fix your door lock actuator problems: Mustang Door Lock Actuator Retrofit

Lots of pictures and instuctions on how to do it...

Stuck with door lock actuators that don't work and don't want to pay the $50+ for a new one? Tried the junkyard ones and found that they last six months and freeze up?

A new actuator for less than $5. Fix one side for $18, do both sides for only $25. I don't sell parts, I don’t make any money off of the upgrade, I just tell you how to do it cheaply and easily.

Here’s a picture of the new actuator installed:
