Re: dimmer switch replacement on 85 k5 blazer
85 is dir lever actuated, not floor mount, correct? If so, pretty easy, drop the dash filler under the column, then loosen the 2 mounting bolts that hold the column up against bottom of the dash. The dimmer switch is on top of the column, piggy backed on top of the ign switch, and actuated by a steel rod. If you work the dimmer switch lever with one hand while feeling on top of the column with the other, you should feel the rod moving. Follow the rod down the column and it will take you to the dimmer switch. Held on by 2 small bolts, you might luck out and just need to adjust it by loosening the bolts and sliding it up or down as required. Good luck, Jim.
