Power lock fuse/circuit breaker (87)

Okay, so my power locks went out the other day, took the power seats with it. I determined it was the fuse. I look in the manual and it turns out that its not just a fuse its a curcuit breaker (I think, its larger than a fuse, metal and has two prongs on the bottom just like a fuse). Anyway removing it and putting it back fixed the problem, temporarly (it does every time temporarily). After resetting it the second time I went to take it out when it failed again and it was so hot it literally burned me. Is it that I need a new circuit breaker, or is it likely there is a bigger problem. I should probably note that when it happened the first time my idiot friend and I were entering tons of random numbers on the keypad cause we're idoits and looking for cheap comedic effect. Thanks.

Sounds like you have a short, you may want to check the wiring.
