interior door handle hard to operate

67 Camaro

It has always taken more effort than normal to open the door from inside (passenger side is fine). Using the outside handle (button)it is fine. I did adjust the striker to make the outside operation easy. Door closes easily without having to slam it

?, what adjustment inside the door would ease the interior door handle effort. It can take quite a pull, not all the time, to open. Seems like it hangs on a latch or some part of the mechanism

or is this indicative of a part wearing out and if so what?

I am going to pull door panel but wanted to know what to look for.

Window crank effort is also more than other side so will grease up track & rollers to see if that is all that needs for that

Re: interior door handle hard to operate

The same type of thing happened to my drivers door on my 68. All I did was take two pairs of vise grips and tweaked the rod from the handle to the mechanism.

Re: interior door handle hard to operate

i had that issue with my 67 and found that it was the interior door handle it self. pull the handle and inspect the spines. i found a hair line crack that would cause the female portion of the handle splines to spread slightly when pulling on it. also, the retaining spring wire on the handles in is prone to wearing out. a new repro handle and spring wire fixed it like new.

Yes indeed, this.

I had to do this with my P/S door when I put things back together after paint.

I can't complain, but sometimes I still do.

Thanks for the tip. IDK what the rod "should" look like but will look to see if it appears to be angled/twisted in some way.

I have had the "door" handle off before...will look closer for any signs of cracks around the spline. It is held on with a screw. The "window" handles are spline and have the "U" type holding clip. Those have been replaced

P.O. did not install the large backing springs or plastic panel protector washers on any of the handles when he replaced the door cards so I put those in on all 4

Re: interior door handle hard to operate

Your handles must have been replaced. My 67 doesn't have screws in any of the handles.

Re: interior door handle hard to operate

Al, IDK if my interior "door" handle is original or not. It has a small bolt that screws into the threaded spline post of the door mechanism. It does not attach with a clip like the window cranks

The window cranks are held on with the U type clips. All of those have been replaced with re-pop's

It is time I ask this question as I've tried logic with no success. How did you post the multiple quotes in this post? I have tried the "Multi-Quote, but I must not be doing the procedure correctly. sorry for the temporary hijack, but if I can take a moment to learn it real quick I'll be good to go.

Thanks,

yes, i just replaced originals with repops. both were held with clip, no screw. like i said, the crack was barely visible until i took the handle off, then i could see how it was spreading when pressure was applied. i would have to give it a hard yank to get it to pop open. thought the rod was bent or failing until body shop took door apart for paint and realized it was just the handle itself. i replaced the mechanism too just to be safe but after inspection the body guys said the handle was all that was really causing the issue.

Well Al, IDK if my handles are original (doubt it) but the "door" handle is held on with a small screw/bolt that threads into the spline of the door release mechanism. I will take it off and see if it is cracked as you describe

My interior was "Deluxe" so the interior door handle has a screw holding it on (link)



I did pull the handle and there is no cracking or stripped splines on it and the spline stud it attaches to is in very good shape

Going to pull panel to look inside and see if something looks "off" and grease what I can see and also grease the window rollers

Got it! For some reason that just made me look pretty geeko. Oh well, at least now I really know how to do it, haha! Thanks,

Re: interior door handle hard to operate

I had the same problem on my 67 and a 68 that were driven quite a bit so the door handles got used frequently. Turned out the design of the mechanism that the interior door handle attaches to is pretty wimpy with just a metal to metal contact surface and spot welded together sections of stamped sheet metal holding the splined shaft in place. Not a very long term design.

The return springs were broken in both so the handles did not return back all the way to the level position and may not have been allowing the latch to operate properly from the interior handle because of this.

The metal to metal bearing contact problem resulted in the sheet metal housing wearing a once round hole into a slotted shape that allowed the handle to move around quite a bit making it sloppy and causing the linkage to no longer travel the distance it was designed to. This also probably contributed to the door latch not not working well from the inside door handle.

I ended up experimenting on the worn out parts to see if I could fix them. I separated the halves of the housing and welded a thicker gauge washer over the worn out back side using the conical shape of the stamped housing to center it. The tolerances between the housing and splined shaft were pretty tight when the spring was in place but when the spring broke then the shaft moved around a bunch. This is probably what caused all the housing wear. I made new springs from spare spring steel I had that was the same gauge as the original parts using the broken pieces and some good parts as a guide to the correct shapes. Greased everything with white lithium and reassembled with stainless steel rivets in place of the original spot welds.

They worked fantastic. I have since done this to over a dozen of them for friends and family. Same mechanism is on the 67-71 Chevy trucks too.
