I have a very basic understanding of electronics, and I had an issue with the "blower motor resistor" in my vehicle. I bought a new one to replace the unit and it fixed my issue. I'd like to repair the old one that's in there and keep it as a backup. I've checked everything I can think of but still haven't found out what's causing my issue. I've included a photo of the circuit and what results I got using my multimeter.
When I tested the transistor Drain to source on my diode setting, it would flash a reading (around 1.5) then go to OL. I'm not sure if this is normal or not?
Unfortunately I have no way of testing the cap, but it looks to be in good shape at least.
