After installing the heater casing, the next step was wiring up the motor and electronic control module. The electronic control box, potentially sensitive to heat, was tucked away under the passenger dash. A Molex connector joined the harness to the fan motor, which passes through the dip switch firewall hole,......
See air distributor box restoration post. Now that the heater and fan are temporarily installed, we can test the air flow into the plenum and out through the air distributor box and demisters. Bruce Murray, who installed his new heater a few weeks ago, was the first to discover that......
When this blog was started back in June of last year, not much thought was given to the “tags” which can be applied to each post for classification purposes. So a year later, all the old tags have been deleted and replaced with ones that describe process steps rather than......

Never easy to read, especially at night without illumination, these labels were mostly reminders to the owner about what the levers did. As previously discussed, the......
The Mk2 antenna, located just outside the A-post (door/window pillar), came in a variety of configurations since many were installed aftermarket by Jaguar dealers. In our case, the surviving radio turned out to be a 1970s Sanyo replacement for the original Radiomobile radio while the antenna, a simple manual extended......
The Smiths small gauges — oil pressure, coolant temperature, fuel level, and voltage (which replaced the original Lucas ammeter) — have face plates tailored specifically for Jaguar models, but share innards with other Smiths gauges installed in most vintage British cars. All use either transmitted resistance value to modify current......
