1999 GMC C1500 V8 Four Wheel Drive Automatic 183500 miles
My sons ATC fuse under the hood keeps blowing. It is usually a 20 amp fuse. I put a 30 amp fuse in it as that is all I had handy, it worked a few days and then that one blew too. I unhooked the actuator and the push button 4 wheel drive selector and tried to put a 20 amp fuse in it and it blew that right away. I did this with about 5 more 20 amp fuses and it did it to every single one of them. If I put a 30 amp fuse in it it won't blow it right away, but I am thinking it will blow it in the next few days as we have to use 4 wheel drive everyday to get out of our driveway.
I unhooked the actuator and the push button selector to go thru the process of elimination but since it blew the fuse with them both unplugged I am stumped.
Any help would be appreciated. I really don't want to go chasing wires, but if I have to I will.
have the same problem?
