The one thing that has cropped up after my AC system upgrade is the fan switch will not stay on high. It runs there, but let go of it and it drops down to the highest variable speed setting.
Anyone seen this and have you come up with a fix besides replacement? I have not begun to look into this yet, just thinking I am not the first to see this. My transistor still sits here waiting for its failure.
AC fan switch detent?

Hey Ross, not sure about your issue, but I'm gonna move your thread to the "Interior" forum, which I think is more proper for this type of issue
Good luck

Re: AC fan switch detent?
It looks like I have answered my own question.
Removed and inspected the switch this evening. It is basically four parts. A mount, operator, adapter housing and the board and connector. The operator consists of a housing that supports the shaft and max speed switch. There is a small piece of spring steel that creates the detent. The bit of plastic holding the detent spring broke preventing any spring.
Unfortunately while testing before removing the blower switch I got a whiff of the tell tail smell of smoke escaping an electrical component. No variable speed anymore.
There's nothing I can see that I could have shorted. I suspect the board took this opportunity to spank me for thinking I'd finished the AC upgrade project.
I am now on the hunt for another discontinued part.
