Well, I realized the 50A fuse is really a fuse. To us "dumb guys" that have seen fusible links before, I guessed wrong. IMO, the engineer made a poor design because physical confirmation of failure requires the use of a continuity tester (which I have) or disassembly. (The window to the fuse is underneath and, therefore, not readily visible. That's about as dumb as shipping a b-load of cars with bad fans!) BTW... I used Chysler's website to confirm the supposedly replaced the fan within a year of sale -- per the TSB.

Yep, I'm a bit PO'd that it took too long to spot the "easy" problem. Of course, I had to have OReilly's send a replacement to the store nearby ($7). That's a bit high for a fuse too.

Next, I'll have to determine (or TRY to determine why the fuse blew). And, wonder if it will blow again. I'll Google the net and try to decide what target resistance is acceptable for a fan. (Yeah...it might be in the FSM which I spotted in this forum. Thanks for that whoever posted it!)

One thing I should clarify is there's NOT a fuse for the FCM in the DS fuse box. According to the FSM schematic, power to the FCM is supplied via that same 50A fuse used to power the fan. (I read some confusion on this.) Anyway, I guess the PTCM "sees" when the FCM isn't getting power and triggers theh low coolant warning light.

The fan will turn using short bursts of 12V via my battery charger. Then...after trying that, I saw the fan may actually have a 6V limit? At least the 5 stages of power peak under 6V. Hopefully, I didn't damage the fan coil (if not already failing). I only "tapped" the wires together to verify the fan would move. I didn't hold the wire together long enough to turn the fan more than a 1/4 turn with each tap. I only jarred movement. (That's because I didn't know what load my battery charger could handle! LOL At least I know my charger has an internal resetable circuit breaker.)

Tomorrow, I will measure fan coil resistance and, likely, install the replacement 50A terminal fuse....unless I determine can coil resistance is too low.
