Ok, so this is a direct re-ask of a question I just read on the forum, but in following the request that we not re-hash old threads, here it is for my own clarification....

I have pulled out the actuator, and even though I can't get it all the way apart, I can see into it well enough that I can tell that the gear is broken, much like the picture posted by HotZ28. Hopefully, if I replace this, I will get air out of the middle vents... Ya Hoo...

Here is the re-ask:

What I pulled out looks like the Rock Auto picture for part #1612492, with the arm, and all, but it also looks like the picture for #16141822, but it shows it from the other side. Presumeably, they are both similar, and the one for the CJ2 option also has that arm on the top side, right? That would be the one I need, according to HotZ28's response in an older thread, but I just want to make sure, since they are different enough to be $10 different in price.

Thanks, and I appreciate all of the help from this board.

Hello i got mine out and try to take it completly apart but was unable to do so but what i saw the gear was not broke. What would be a another step i could take or try to get my air coming from the center vents again almost forgot 96 park ave.

The actuator referenced in the previous post, is used for hot/cold blend between the heater core & A/C evaporator and has nothing to do with air flow direction. You must have a vacuum problem @ the programmer, or feeding the programmer.

Hello were can i find the programmer and what does it look like, and how to find a vaccum leak.

The best way to find a vauucm leak is to use a hand vacuum pump (brake bleeder). Remove the vacuum line @ the manifold and hook it up to the pump & pull 20 in hg on the system. Wait to see how long it will hold vacuum. The programmer is under the passenger side dash, mounted in a vertical position next to the heater core box. Occasionally, the vacuum line connector at the programmer will restrict vacuum to the vacuum actuators. We have some threads discussing this problem & a fix in the archives, do a search for them.
