I just recieved the set of UPR temp control knobs right before lunch. So I run out to my car to make the switch. They look good and fit well until I started turning the temp knob and the fan location selection know (middle and right). They just spin all the way around. I don't like it at all. The factory knobs have a raised area on the back of the knob that contacts an inner ring on each dial to provide a positive stop in both directions. I just wrote UPR and asked them is this is by design and if so I don't like it. Anyone else have UPR knobs and notice this or is it just mine? I know Rygen just got some of these if I remember right. I got the pure round ones that match the shape of the radio button. Part number 1003-05-5 :sosad:
