Against my better judgment, I purchased a budget-priced heater blower fan for my 1990 Jaguar XJ6 Sovereign. The owner told me they usually test them before selling. I should have stopped there but didn’t. The end result was a partial refund and the possibility of rebuilding the thing myself. That idea surfaced when I checked on the price of a rebuilt one — $550! And that’s only for one side. Jaguar for some odd reason put one under either side of the dashboard. This evening, my son and I took apart the non-working fan and found it quite interesting. Watch the video below to see what we found.
