heater blower FUSE

[jeremy5780]

1985 CJ7 I upgraded the blower motor to the one for the blazer. Works great I had a 30 amp fuse in the fuse panel, today I noticed the fuse was melted (looked like a melting ice cream cone). However the fuse did not blow and the motor was still working. I replaced the fuse with a 20 amp and turned it on for a few minutes and it worked fine and did not blow. It calls for a 25. The fuses I was using were the cheap kind from a dollar store. Anyone ever have a problem like this? Does the blazer motor require a higher amp fuse?

Right off hand I would suggest the recommended fuse, 25 amp, but avoid the cheap stuff.

Go to NAPA, and get some 25 amp fuses.

My upgraded blower motor's driven by 14 gauge wire and a 30 amp fuse.

is your set up different?
