Fresh air blower controls Options

[era vulgaris]

So after a year I've finally gotten around to troubleshooting why my fresh air blower fan doesn't work. Some deoxit and scraping away crud with a long screwdriver got the low and mid settings on the fan to work. It seems though that the little borders that create a detent in the slider movement between settings is preventing the contact arm from reaching the third setting. It's like the contact arm isn't long enough to make it over the last detent border. Anyone know if there's anything that can be done? Any adjustments?

You can (hopefully!) see how much bigger the last detent is in the pic. Not an easy shot to get through the ashtray hole!!!

On closer inspection I can see now that those "detents" are actually melted plastic and not supposed to be there. Yikes!
I was able to clean the contacts by reaching under the dash and up behind the controller with a q tip in one hand, and spraying contact cleaner from the front through the ashtray opening. A bit of the old reach around! (IMG:style_emoticons/default/shades.gif)
Went ahead and went through the entire car cleaning every contact I could find while I was at it.
I'm about a week away from permanent top off weather until fall, so not a huge issue that it's all working. I'll prob just leave it as is for now. The medium speed isn't bad if I need it, and I really don't feel like taking the air box off again to clean the fan. I spent almost 2 hours in the front trunk today getting the new seal in. I've got muscles in my arms and back that I didn't know I had that are sore from trying to push and hold the air box into place while getting the mounting screws in. In addition to a raging headache from gas fumes from being right above the gas tank. (IMG:style_emoticons/default/smoke.gif) (IMG:style_emoticons/default/icon8.gif)
