I saw a vid about the issue regarding bad FSR and bad blower motors. Either one can cause numerous issues, but which if either can cancel out currents through the fuses. There is no current top or bottom on the aforementioned fuses. Still getting to checking the beastly 200 amp in the trunk area. Thanks,

This is bizarre. I plug up the ebay unit CCM and nothing works because the fuses are dead on both sides. NO power. I check the rear F200amp fuse n board and they are all whole, at least the side that is showing/black plate/is whole.
When the unit is unplugged the rear blower motor runs when the X is on #2position or running. Turn it off and the blower goes off. Plug in the unit and the rear blower fan no longer works. MY guess: FSR. It controls current flow in the circle from the blower motors to the control unit/modules and back. SO I can't figure out what else it could be other than the $28. FSR Behr part. Last time it was changed/10years ago. Feel free to offer more advice and counsel about what else I can look for. Thanks all.

Continuous Terminal 30 voltage supply can't go down unless the wire or fuse is broken. Are you really measuring voltage against ground (not current) on the fuse rail connector?

Clavurion: First , thank you so much for those amazing diagrams. They are so helpful in understanding more about this and other issues I have. One thing, are the fuses in a system used to control the amount of 12volt energy flowing to a given location and that items amperage needs? It makes more sense now, but I still have to find the reason those fuses aren't lighting up. First chance I get, voltmeter test the fuses location. Is it safe to remove the fuse and test the fuse openings? Thanks.

Yes, there is no danger measuring the voltage on fuse connector. The rail side of the fuse connector should have battery voltage. On terminal 30 fuses there should be continuous voltage regardless of ignition switch position. Terminal R is ignition switch pos. 1 (radio position) and terminal 15 is ignition switch position 2. You can see the supply terminal mentioned on the diagrams.

I am checking volts with voltmeter today. But I did check current using a grounded test lamp. I checked all the fuses, included the 50amps and they all lit up with current on both sides. I checked the F200 in the rear, I noticed the top fuse had a large black center core and it was in one piece. I checked fuses in the rear hatch and they all looked fine. I am pulling the FSR today and hoping to find the resistance settings so I can check if it's good. Not sure how to test the blower motor as it's under the dash. Thanks C.

Clavurion: It works, kinda. Found the faulty fuse, 7.5/34. Hairline fracture, continuity test. New fuse, IHKA lights up, works perfectly except issues with fan function. Then, poof, fuse blows. New fuse, same thing. SO, I removed the FSR. Last guy to put the replacement in messed it up a bit. Broke the securing clips. Anyway, I am trying to learn more about resistance. Is there a diagram that shows each pin and the resistance rating? I am able to get readings but I am not sure how bad they are. Just figure they're bad because it blows the fuse. Thanks again.

BAFFLED, removed the FSR. Replaced the blown fuse. IHKA turned on and didn't notice a fan blowing, but I did adjust the temperature and it blew the fuse within a minute. 34/7.5, how is this possible? It maybe that the FSR is fine and it's another issue? I am going to keep testing the IHKA n replacing fuses until I can figure out if it's AC related. I didn't notice if the fan kicked on in cabin, but the fan light bar was working with the switches.

Does it happen if A/C (snow flake) is not turned on?
