You have a short! You have a wire going to ground somewhere. Start with the ATC circuit.
Do not use a larger fuse then rated. If I am correct, and I feel I am, you could start a fire.
Get an electrical tester, unplug the fuse and check for continuity to ground. The battery side of a clean metal surface should give you no continuity (open). But should give you about 13 V DC.
The line side should not give you continuity or V. If it does you must trace the circuit, look for wire splices, tape, broken wire casing that kind of thing.
Or go to a shop that does car electrical work.

IF the fuse blows immediately, you've got a dead short. Trace the wiring harness backwards from the transfer case and shift motor, looking for chaffing or rub through.

SOURCE: Chevy truck running rough 150,000 miles

Find out why the engine light is coming on, it is the info u probably need to fix the running rough problem. Most auto parts stores will read the codes stored in your trucks computer for free, write them down, and ask what they mean and how to correct the problem. If u need more info, return to this site w/ codes for further help.

I have a 1996 chevy chyenne 305 vortec 4x4 and my ECM fuse keeps blowing. After the first time it blew I replaced it the truck started, ran for 10min and died, the second time I did put a 30amp fuse in...

start chasing wires. Sounds like something is shorted or worse, a hot wire may be grounded out.
Good place to start is all wires headed to the started as that is a common place for a power wire to melt against hot exhaust.
(that was the case for my 99 chevy)
Check all other fuses and make sure none are blown.

My atc fuse would keep blowing I put a bigger fuse it didn't blow that but I herd a zap noise from my TCCM now my 4x4 won't work 1999 jimmy

What you have done? You Just damage the TCCM and that's why you will not manage to shift 4x4. Why this happened? Because you had shortage somewhere and you receive blown ATC fuse.You put a bigger fuse in capacity where the was stronger to blown and the fault moved to the tccm system which was not protected and blown.Ask for an expert to check and see whether the fault is easy to get fixed.

EMC1 fuse keeps blowing immediately in 02 chevy express 3500LS 5.7L engine

That fuse powers the pink wire that runs to the coil, injectors, and pcm.
If the short isn't obvious, I disconnect everything I can from the wire and then put in a fresh fuse. I turn the key on and check the fuse. If it blows, I know it's something I haven't disconnected or the wire itself. If it doesn't blow, I start reconnecting things one at a time untl the fuse blows again.

Chevy silverado keeps blowing fuses

Your 20 amp fuse will not blow if glowplug wire shorts. each plug draws 15 amps which is 120 amps total.I think there are in line fuses for them. Try to wring out where each output from the fuse goes, disconnect all and reconnect one at a time till it blows.That should point to your problem process of illumination! Good Luck!!

Fuse #12 for 2000 lincoln towncar keeps blowing

fuses are a safety device. they are made to blower when to much load is drawn over them. some component on the circuit is shorting out. if possible unplug all the items on that circuit. put in a new fuse, then reconnect component one at a time until the fuse blows again. a process of elimantion. it may take some time, but it will be expensive to take it to a dealership.
