Factory A/C in 1967-1972 Darts

I've rebuilt a couple of the slider switches by melting off those pins on the back (or filing them so they allow the rear cover with the nipples to come off. I agree about being extremely careful with those nipples. Then separating the "wafers", being sure to keep them in the proper order, and oriented correctly. I believe I used locksmith graphite to lubricate them, then put them back together and either re-melted the pins or tapped, threaded and machine screws.

They came out great and easy to operate.
