After reading the article in TDR magazine on heatere control knob, I went to the local Dodge dealer to purchase a knob. The article said he paid $7. ?? for one. My local dealer wanted $14 fo one. So, I went to Autozone & found 2 for $7 that were for a Honda but fit like a charm. Neat thing about them is the glowing indicator is a close match to the orange colored needles on our gauges. Just a little FYI
