Have been having problems with my A/C blower motor in my International work truck.
The motor will go off for a few seconds than go back on.
Has been in the shop several times. With the intermittent problem they were having trouble finding the cause.
They have replaced the blower motor; heat exchanger; wiring harness; trying to fix the problem.
Friday it quit all together while I was out on the road.
Since it was 80 degrees I looked around and wiggled some wires to see if I could get it to come back on.
Sorry about the picture quality but this is what I found.
At first I was stumped because I thought this is why you have a fuse.
To prevent this.
The fuse is half melted but it is not blown.
Then I realized the side that is burned is the hot wire side.
I assume it had a bad connection and melted the metal prong right off the fuse from the heat.
Luckily there was no fire.
So back to the shop it goes.
I'm guessing they will replace to whole fuse box to fix any bad connection problems.
