Hi Mike and thanks. I have the M37 fuse pop issue on my 08 rubicon. it occurs when the brake pedal is released and engages the stop switch. I replaced the switch and still it pops when the pedal raises to engage the switch.
Additional info: This fuse is 10 amp and has the brake switch circuit, ABS, Electronic Stability Program, and fuel pump on it.
Sorry to take long to get back with you. I have rated your service and hope all is well.
The problem ended up being a brake controller for operation of trailer brakes installed by a previous owner was connected with, what I have always heard called, suit case connectors. I completely uninstalled this, put in a fresh 10 amp fuse and we are good. Took her up to the mountains today. Was a good day.
I appreciate the help and service.
