So, after a nice 16 hour day at work, upon finally getting back in my car after a brisk walk through beautiful downtown Hartford at 11pm, my cabin fan refused to spin. Like a boss, I replaced the speed controller about 2 years ago...with a used one. That logic sure does seem flawed to me now.

Anyway, I already ordered a new one (ride to work at -3 this morning was awesome), but is there a chance this could've also been the cabin fan going out? I know the contacts can get corroded and/or the fan itself can go. Symptoms seemed textbook speed controller to me though, cabin fan just stopped after running for a minute, wont run on any speed.

Hooray Friday

Could be either, but probably the resistor if the fan quit all at once and wasn't noisy beforehand.

If it's the fan, sometimes the seized fan cooks the old resistor anyway.
