Page 1B-37 of my '91 camaro manual says:
"(Remove) Temperature control cable at the air conditioning module.

What's got me stuck here, is I'm not exactly sure what this kind of retainer is, and how to remove it. I've tried prying away at what I thought was it with a plier, but I didn't want to do break anything by misunderstanding.

Here's a walkthrough of pictures to where I'm stumped: (excuse the massive size of pics)
Starting from Passenger seat.





"Push nut retainer"
Again, I don't know what that is (what type of bolt?) in the above picture, nor do I know how to remove it.
Help would be appreciated!

- All I want to do is fix my stuck temperature cable D: -

 

That is a push nut. It simply pushes on, and the slits in it give enough way to go on, but the sharp edges bite into the pin. If the pin is plastic (I don't remember) be careful and pry it off - easiest to get a small flat-tip screwdriver that is sharpened, get up underneath it, and pry upwards enough to get enough of it's edge up all around to get your needlenose pliers on it and pull gently, kinda wiggling alog the way.

To replace it (assuming it didn't break), flatten it out (light tap with a hammer) and push it back on. If the push nut breaks, any auto parts store has an assortment in a box (HELP! section) for about $3.

JUST DON"T BREAK THE PIN IT"S PUSHED ON!

Good Luck.

 

Pry it?
If I'm thinking right, then any movement in the opposite direction it was push upon will cause the fins to -dig- into the pin its hugging. Right??

So then the force I apply to pry it off would make it more impossible to remove ...

 

Pry up the individual little tabs of the push nut, one at a time; NOT, under the outer edge of it.

 

You can practice on the dome light - same push nuts there holding it to the roof - I know those are metal pins that won't break. That's just how I've always done it - just pry up on the edges enough to get a grip with the needlenose pliers.

 

Sometimes you can gently pry the base down enough to get a pliers around the base. Then gently turning the nut while pulling down will often release it without breaking anything. Most important not to break the pin. As above, the push nut is easily replaced.

 

Alrighty, so I finally got the demon out, by prying/twisting/ and finally breaking it.


And so my repair goes on, and I see rust all over this lever. It's rock solid until i used the pliers and slowly inched it around, opening and closing the blower to the heater...with excessive force.




But before I make any conclusions...Is this a simple lubrication fix that I think it is? or does this problem extend deeper into the blower area.
I'm about to buy WD-40 later to lubricate, but I just want another's opinion before I do so.

 

I'd say just a bad rusting issue - I'd skip the WD40, get it loosened where it turns freely and apply a slightly goopy grease that won't evaporate (like white lithium) - then it should stay greased for several years (like door lock mechanisms do). Check the door and make sure it moves freely on it's other hinge as well.

 

Thanks to everyone, I can say now that I'm done fixing my stuck temperature cable
