Electrical problem
2001 Chevy Blazer 6 cyl Four Wheel Drive Automatic 190km miles

Okay, just to start i had used 4x4 on dry pavement a few times over the course of a couple weeks leading up to this( i know it wassnt the smartest thing but i was silencing another problem i had at the time but have since fixed) So everytime i put in a new 10amp fuse into slot #15, everything appears to work fine until i put it into drive, remove my foot from the brake and roll, even an inch. The fuse blows again, ive tried everything i can think of, taken apart the in-dash switch and the TCCM and both circuit boards looks fine. some of the wires on the TCCM harness are a lil corroded but i stripped them and i have them in there temporarily working. Any help would be much appriciated. Thanks.

you guys cause yourself more toruble than you need. that circuit feeds three things , transfer case shift control switch but it also feeds interior lights.,front axle indicator switch on the right side of the diff case, and front axle vacuum switch by the wiper motor. unplug one of these at a time and see if the fuse still blows. if it does with all of them disconnected then it's a wire touching someplaceand shorting out. it is a brown wire in the harness.
