Thrift air switch help

[bonehead]

I am having an issue with my thrift air fan switch. The switch and cable unit is new. It pulls in and out just fine, but when I try to turn the switch on for fan speed it only goes to the first speed. The second and third speed positions just spring back. I've made sure the cable is not kinked. I even removed it completely and it worked ok out of the dash. What do I need to do to this thing to make it stay in the speed where I want it.

Help? Anyone know how to solve this one?

I’m not familiar with that specific switch/cable, but assuming the switch is operating a cable, it sounds like there’s an adjustment problem between the far end of the cable (the core wire) and the end of the cable jacket where it anchors, much like on a choke cable. If the end of the jacket is too close or too far away from the tip of the cable wire, (depending on the setup) the first position may be extending to maximum travel and any movement beyond that just bends flex into the cable assembly which wants to spring back. Depending on what’s wrong, additional jacket may need to be removed to allow more travel from the jacket anchor to the lever being operated.

It is not the in and out of the cable that is bouncing back, it is the twisting of the knob to activate the fan. when I twist it, it springs back. Maybe it is a bad repro switch.

It seems to me there should be a ball type connection between the switch and the cable to allow the switch to twist independent of the cable pull. Has anyone had a stock switch apart?

Prior to installing the new cable and switch, did you test it out? If not, uninstall it and test to see if it springs back. If it's springing back, it's a problem with the switch. If it doesn't spring back, sounds like it has to be reinstalled anyway. If you didn't, get the switch in place and tightened 1st, then attach the other end beneath the dash.

I tested the switch out of the dash and all three speeds worked. But when installed it binds and springs back. I have routed the cable as straight as is possible. Any other ideas?

Sorry, I'm stumped. I took mine out last week for lubing and had no issues like this after reinstalling. It's such a simple piece that I can't fathom why it would do this, so I'm leaning towards it being defective.
