The XJ6 thankfully retains the classic triangular front ventilator windows inherited from the Mark II and earlier saloons. The early 1960-style windows were opened by simply undoing the latch and pushing or pulling them open or shut. For the XJ series, Jaguar elected to “upgrade” the ventilators with an open\/shut twist knob that eliminated the fastening latch entirely. The only apparent advantage is that the XJ window can be opened to all angles; previously the ventilator moved in incremental “clicks” that prevented wind resistance from changing the glass position.<\/p>\n

Drawing of large vent twist knob<\/p><\/div>\n

The disadvantage is that a large twist knob must be placed on the door panel, and Jaguar didn’t give this much design thought. <\/p>\n

The black plastic knobs — Jaguar part numbers BD35943 (knob) and BD35953 (metal cover) — remain available in the aftermarket for about $20<\/a>.<\/p>\n

But instead of replicating Jaguar’s original plastic faux pas<\/em>, there is an alternative opportunity to re-imagine the door and upgrade the decidedly cheap looking black blob.<\/p>\n

\"\"<\/a>

New knob design (left) displays a Jaguar logo<\/p><\/div>\n

The original knob (see right panel above) has a thin metal cap that snaps in to cover the fastening bolt underneath. It looks quite plain and undistinguished compared to the chrome fittings elsewhere on the door panel.<\/p>\n

Our new knob design starts with a more robust “Jaguar” cap but it still must be removable so that the hidden bolt that attaches to the ventilator turning mechanism can be tightened down. The cap has a very small gap just visible along the side that allows a small screwdriver to lever it up if necessary.<\/p>\n

\"\"<\/a>

Revised knob with embossed Jaguar cap<\/p><\/div>\n

The knob hollow shaft — a bolt passes through it — contains a slot that fits into the turning mechanism. The shaft must be a precise length so that the knob’s position is correct in relation to the door panel. <\/p>\n

The new Jaguar cap is fabricated from XJ6 aluminum wheel logo caps. A wooden plug was fitted into the plastic knob body that was affixed to the cap with epoxy putty.<\/p>\n
