faulty wiring or too low of a fuse, shorting out because the wire is touching metal or another wire
You have a ground wire that isn't grounded causing a shortage therefore blowing the fuse....I would start with the ground wire that is connected directly to the starter itself
If it blows when trying to crank, the starter has failed.
could the pcm fuse be blowing because of a short in the air conditioning switch I have seen the starter be the cause of a blown pcm fuse.
A fuse blows when the current in the circuit passes what the fuse is rated at. If you are blowing the ECM/starter fuse, the starter is probably bad.
If it blows when cranking the starter has failed.
I believe the starter solenoid is on the same circuit. A failed starter is most likely the problem.
It is very common for the starter to be the cause of that fuse blowing.
Unhook the wires on the starter, replace the fuse, turn the ingnition key on as if you were going to start the car. If the fuse does not blow, it is your starter. I just had this problem with a 1996 Dodge Stratus. I replaced the stater and it now works.
The starter has failed.
Short in the wiring or the starter is defective.
I have a 2001 Dodge Stratus 2.7 and had the same problem. I ended up replacing the fuel pump in the gas tank.
There is no starter fuse on the New Beetle.
