I just replaced a shopping list of electronics. The list included a Darlington transistor and a shitload of other resistors and transistors. All this shit on some control board attached to one A/C fan blower in the Jaguar I mentioned before. Why they felt the need to put all that shit- half on one control panel in the fascia and then two quarters divided between the two fans I cannot understand. It was beyond my capability to test each component and much cheaper for me to just order replacements and resolder them all into the control board. I think it cost less than 20 bucks and now the fan works and I have a spare set of everything for when, not if, the other fan goes out.
