No 12v and REAR windows do not roll down

[Indian_Joe23]

So thins began when purchased MeLe Battery mount for my 16 FiST. It's a great product, awesome on engine bay space (+ weight reduction). So after installation I realize that my master window switch is half-lit and the rear windows wont go down; same with rear switches. Then connecting my dash cam to the cig. lighter I also realized my 12v was out to (same with the rear) I double checked the fuses in the engine bay and in the glove box, and they were ok. So I did the bright decision to think meh its probably the cons of down-sizing the battery (lol) and if I go back to stock it'll all go back to normal... WRONG SON. Now I'm back to having a cow in my engine bay and no 12v and rear windows . Any help will be great, and yeah ill be honest I procrastinated the trouble shoot and kinda stuck looking at schematics on pro-demand lol. PS the battery mount is sick! Highly recommend it; just don't bagel it like I did lool, I'm thinking of sticking it back on once I fix my bb.

What is the battery voltage? if it isn't where it needs to be that can upset things in a CAN bus system. Remove the MELE battery mount. see what happens. Also check the battery ground while you are at it! Good luck. Keep us update.

It's probably your master window switch.

Terribly sorry for the late reply bruv, it turns out I tripped a (15 - glove box) fuse and had to re-learn ALL 4 windows. shes been working since last year Jan 18 lol, many many thanks!
